A numerical value indicating the relative position of the fader operator 51 with respect to the first end TC1 is acquired.

The mode switching unit 64 switches the operating mode of the acoustic control device 1 between normal mode and assist mode in response to an input operation on the mode selector switch 4. Although details will be described later, the normal mode is a mode in which the audio control device 1 does not assist when mixing the first music and the second music. The assist mode is a mode in which the sound control device 1 assists in mixing the first music and the second music without causing any discomfort.

[Volume control function]
The volume adjustment unit 65 adjusts the volume of the first music piece to be output from the first channel and the volume to be output from the second channel based on the positions of the fader operator 51 and each operator 33A1, 33B1 acquired by the position acquisition unit 63. In addition to adjusting the volume of the second song played, the balance between the volume of the first song and the volume of the second song is adjusted. Specifically, the volume adjustment section 65 adjusts the balance between the volume of the first song and the volume of the second song according to the position of the fader operator 51. Further, the volume adjustment section 65 adjusts the volume of the first music according to the position of the first operator 33A1 of the first channel fader 33A, and adjusts the volume of the first music according to the position of the second operator 33B1 of the second channel fader 33B. 2 Adjust the volume of the songs.

[Processing when operating the crossfader]
FIG. 4 is a diagram showing changes in the volume of the entire first song and changes in the volume of the entire second song when the crossfader 5 is operated. In FIG. 4, a numerical value indicating the relative position of the fader operator 51 acquired by the position acquisition unit 63 is set on the horizontal axis of the graph.
The volume adjustment section 65 adjusts the balance between the volume of the entire first music piece and the volume of the entire second music piece based on the position of the fader operator 51 of the crossfader 5 within the operable range. Note that the volume of the entire first song refers to all the volumes of the first song, including the volume of the high frequency band, the volume of the medium frequency band, and the volume of the low frequency band. The maximum value of the volume of the entire first music piece is the first set volume V1st set by the first operator 33A1. The balance between the high frequency band, medium frequency band, and low frequency band in the first song corresponds to the ratio of the set level H1lv of the high frequency band, the set level M1lv of the middle frequency band, and the set level L1lv of the low frequency band. are doing. The same applies to the volume of the entire second music piece, and the maximum value of the volume of the entire second music piece is the second set volume V2st set by the second operator 33B1. The balance between the high frequency band, medium frequency band, and low frequency band in the second song corresponds to the ratio of the set level H2lv of the high frequency band, the set level M2lv of the middle frequency band, and the set level L2lv of the low frequency band. are doing.
Note that the direction from the first end TC1 to the second end TC2 is the +DC direction, and the direction from the second end TC2 to the first end TC1 is the -DC direction.

When the fader operator 51 is arranged at the first end TC1, the volume adjustment section 65 sets the volume of the entire first song to the above-mentioned first set volume V1st, as shown in FIG. The overall volume is set to the second minimum volume V2min.
The volume adjustment section 65 decreases the volume of the entire first music piece and increases the volume of the entire second music piece as the fader operator 51 is operated in the +DC direction from the first end TC1. In other words, the volume adjustment section 65 increases the volume of the entire first song and decreases the volume of the entire second song as the fader operator 51 is operated from the second end TC2 in the −DC direction.
That is, as the fader operator 51 is operated in the +DC direction, the ratio of the second music piece to the volume output from the audio control device 1 increases. As the fader operator 51 is operated in the −DC direction, the ratio of the first music piece to the volume output from the audio control device 1 increases.

When the fader operator 51 is disposed at the second end TC2, the volume adjustment section 65 sets the volume of the entire first music piece to a first minimum volume V1min, and sets the volume of the entire second music piece to the second setting as described above. The volume is set to V2st.
In this way, the volume of the entire first music piece and the volume of the entire second music piece are adjusted according to the position of the fader operator 51 in the operable range RC. Then, by operating the fader operator 51 from the first end TC1 to the second end TC2, the output music is switched from the first music to the second music. By operating the fader operator 51 from the second end TC2 to the first end TC1, the output music is switched from the second music to the first music.

Here, the volume level of each frequency band of each song when the crossfader 5 is operated will be explained.
As mentioned above, the volume of the entire song is determined by a high frequency band signal with a strength corresponding to the preset level of the high frequency band, a medium frequency band signal with a strength corresponding to the preset level of the medium frequency band, and a low frequency band signal with a strength corresponding to the preset level of the medium frequency band. It is determined by amplifying a signal in a low frequency band whose intensity corresponds to the preset level of , with an amplification factor corresponding to the position of the fader operator 331 . In other words, if the position of the fader operator 331 is not changed, by changing the volume level of each frequency band with the set level as the upper limit, the overall volume of each song, and by extension the volume balance of each song, is adjusted. Ru.

FIG. 5 is a diagram showing changes in the volume level of each frequency band of the first song and changes in the volume level of each frequency band of the second song when the crossfader 5 is operated. To be more specific, the first row from the top of FIG. 5 shows the position of the fader operator 51, and the second row shows the volume level of each high frequency band of the first song and the second song. There is. The third row from the top of FIG. 5 shows the volume level of the medium frequency band of each song, and the fourth row shows the volume level of the low frequency band of each song. Note that on the horizontal axes of the graphs shown in the second, third, and fourth rows of FIG. 5, numerical values indicating the relative positions of the fader operators 51 described above are set. Note that although the set level H1lv and the set level H2lv are shown as the same value in FIG. 5, the set level H1lv and the set level H2lv do not necessarily have to be the same value. The same goes for the set levels M1lv and M2lv, and the same goes for the set levels L1lv and L2lv.
As shown in FIG. 5, the volume adjustment section 65 adjusts the overall volume of each song as shown in FIG. 4 by changing the volume level of each frequency band of each song according to the position of the fader operator 51. Adjust.

Specifically, as shown in the first and second rows in FIG. The volume level of the high frequency band of the second music piece is varied within the range of the minimum level H1min to above the preset level H1lv, and the volume level of the high frequency band of the second song is varied within the range of the minimum level H2min to below the preset level H2lv. That is, as the fader operator 51 is operated in the +DC direction from the first end TC1, the volume adjustment section 65 increases the volume level of the high frequency band of the first music piece from the minimum level H1min to the preset level H1lv as the upper limit. At the same time, the volume level of the high frequency band of the second music is lowered from the set level H2lv to the minimum level H2min as the lower limit.

Similarly, as shown in the third and fourth rows of FIG. The volume level of the low frequency band of the first song is varied within the range of the minimum level L1min or more and the preset level L1lv or less, and the volume level of the low frequency band of the first song is changed within the range of the minimum level L1min or more and the preset level L1lv or less. The volume level of the frequency band is changed in the range of the minimum level M2min or more and the preset level M2lv or less, and the volume level of the low frequency band of the second song is changed in the range of the minimum level L2min or more and the preset level L2lv or less. . That is, as the fader operator 51 is operated in the +DC direction from the first end TC1, the volume adjustment section 65 increases the volume level of the medium frequency band of the first song from the minimum level M1min to the preset level M1lv as the upper limit. At the same time, the volume level of the middle frequency band of the second song is lowered from the set level M2lv to the minimum level M2min as the lower limit. In addition, as the fader operator 51 is operated in the +DC direction from the first end TC1, the volume adjustment section 65 increases the volume level of the low frequency band of the first song from the minimum level L1min to the preset level L1lv as the upper limit. At the same time, the volume level of the low frequency band of the second music piece is lowered from the set level L2lv to the minimum level L2min as the lower limit.
In this way, the volume adjustment section 65 adjusts the volume level of each frequency band of each song between the minimum level and the preset level according to the position of the fader operator 51, thereby adjusting the volume of the first song. and the volume of the second song are adjusted, and the volume balance of each song is adjusted.

FIG. 6 is a diagram illustrating an example of a change in BPM during reproduction of the first music piece and the second music piece in the assist mode. Specifically, FIG. 6 shows the results of the first and second songs when the crossfader 5 is operated in assist mode when the BPM of the first song is 100 and the BPM of the second song is 120. It is a figure which shows the change of BPM at the time of each reproduction|regeneration. Note that on the horizontal axis of the graph shown in FIG. 6, a numerical value indicating the relative position of the fader operator 51 described above is set.
The BPM setting section 66 sets the BPM of each song during playback according to the position of the fader operator 51, as shown in FIG. 6, when the operation mode of the audio control device 1 is the assist mode. Hereinafter, the setting of BPM during playback by the BPM setting section 66 in the assist mode will be explained.

As the fader operator 51 is operated in the +DC direction from the first end TC1 to the second end TC2, the BPM setting section 66 changes the BPM of each song so that the BPM of the first song approaches the BPM of the second song. Set the BPM when playing.
Then, when the fader operator 51 is placed at the second end TC2, the BPM setting section 66 sets the BPM of the second song as the BPM during playback of each song. In the example of FIG. 6, the BPM during playback of each song is set to 120.
As the fader operator 51 is operated in the -DC direction from the second end TC2 to the first end TC1, the BPM setting section 66 changes the BPM of each song so that the BPM of the second song approaches the BPM of the first song. Set the BPM when playing music.
Then, when the fader operator 51 is placed at the first end TC1, the BPM setting section 66 sets the BPM of each song during playback to the BPM of the first song. In the example of FIG. 6, the playback BPM of each song is set to 100, which is the BPM of the first song.

When the fader operator 51 is placed in the middle position of the operable range RC, the BPM setting unit 66 sets the BPM of each song during playback to an intermediate value between the BPM of the first song and the BPM of the second song. do.
Although the rate of change in BPM during reproduction when the fader operator 51 is operated in the ±DC direction is constant in the example of FIG. 6, it may not be constant. For example, the rate of change may change as the fader operator 51 is operated in the ±DC direction.
In this way, depending on the operation of the fader operator 51, it is possible to easily align the BPM of each piece of music to be mixed during playback. Therefore, each song can be mixed naturally without any discomfort.

[Processing when operating the channel fader]
FIG. 7 is a diagram showing changes in the volume of the entire first song when the first channel fader 33A is operated, and changes in the volume of the entire second song when the second channel fader 33B is operated. In FIG. 7, numerical values indicating the relative positions of the respective operators 33A1 and 33B1 are set on the vertical axis of the left graph.
As shown in FIG. 7, the volume adjustment section 65 adjusts the volume of the entire first music piece based on the position of the first operator 33A1 of the first channel fader 33A, and adjusts the volume of the entire first music piece based on the position of the first operator 33A1 of the first channel fader 33A. Based on the position of 33B1, the volume of the entire second music piece is adjusted. That is, the volume adjustment unit 65 sets the first set volume V1st, which is the volume of the entire first music piece, between the first minimum volume V1min and the first maximum volume V1max based on the position of the first controller 33A1. do. The volume adjustment unit 65 sets a second set volume V2st, which is the volume of the entire second music piece, between the second minimum volume V2min and the second maximum volume V2max based on the position of the second operator 33B1. Note that the first maximum volume V1max is the maximum volume of the entire first song that can be output from the audio control device 1, and the second maximum volume V2max is the maximum volume of the entire second song that can be output from the audio control device 1. be.

Hereinafter, among both ends of the operable range RA of the first operator 33A1, one end will be referred to as a first end TA1, and the other end will be referred to as a second end TA2. The direction from the first end TA1 to the second end TA2 is the +DA direction, and the direction from the second end TA2 to the first end TA1 is the -DA direction. Furthermore, one end of the operable range RB of the second operator 33B1 is defined as a first end TB1, and the other end is defined as a second end TB2. The direction from the first end TB1 to the second end TB2 is the +DB direction, and the direction from the second end TB2 to the first end TB1 is the -DB direction.
In this embodiment, since the +DA direction and the +DB direction are along the upward direction, the first ends TA1 and TB1 are the lower ends of the operable ranges RA and RB, and the second ends TA2 and TB2 are the lower ends of the operable ranges RA and RB. This is the upper end of RA and RB.

Specifically, when the first operator 33A1 is placed at the first end TA1, the volume adjustment section 65 sets the first set volume V1st to the first minimum volume V1min, as shown in FIG. As a result, the volume of the entire first music piece becomes the first minimum volume V1min.

When the first operator 33A1 is operated, the volume adjustment section 65 changes the first set volume V1st. That is, when the first operator 33A1 is operated in the +DA direction, the volume adjustment unit 65 increases the first set volume V1st, and when the first operator 33A1 is operated in the -DA direction, the volume adjustment unit 65 increases the first set volume V1st. The completed volume V1st is decreased.
In the example of FIG. 7, the rate of change in the overall volume of the first song is constant, and the amount of movement of the first controller 33A1, the amount of change in the first set volume V1st, and the amount of change in the overall volume of the first song are is directly proportional. However, the present invention is not limited to this, and the rate of change of the first preset volume V1st and the rate of change of the volume of the entire first music piece may not be constant; for example, the first controller 33A1 may move in the +DA direction or -DA direction. It may change as it is operated.
When the first operator 33A1 is placed at the second end TA2, the volume adjustment section 65 sets the first set volume V1st to the first maximum volume V1max. As a result, the volume of the entire first music piece becomes the first maximum volume V1max.

On the other hand, when the second operator 33B1 is placed at the first end TB1, the volume adjustment section 65 sets the second set volume V2st to the second minimum volume V2min. As a result, the volume of the entire second music piece becomes the second minimum volume V2min.
The volume adjustment section 65 changes the second set volume V2st when the second operator 33B1 is operated. That is, when the second operator 33B1 is operated in the +DB direction, the volume adjustment section 65 increases the second set volume V2st according to the position of the second operator 33B1, thereby increasing the volume of the entire second music piece. Increase volume. Further, when the second operator 33B1 is operated in the -DB direction, the volume adjustment section 65 lowers the second set volume according to the position of the second operator 33B1, thereby controlling the entire second music piece. Decrease volume. At this time, although the rate of change of the second set volume V2st and the rate of change of the volume of the entire second music piece are constant in the example shown in FIG. 7, they do not need to be constant. For example, the rate of change of the second set volume V2st and the rate of change of the volume of the second music as a whole may be different, and change as the second operator 33B1 is operated in the +DA direction or -DA direction. You can.
When the second operator 33B1 is placed at the second end TB2, the volume adjustment section 65 sets the second set volume V2st to the second maximum volume V2max. As a result, the volume of the entire second music piece becomes the second maximum volume V2max.
Therefore, for example, from a state in which the first operator 33A1 is arranged at the second end TA2 and the second operator 33B1 is arranged at the first end TB1, the first operator 33A1 is operated in the -DA direction, By operating the second operator 33B1 in the +DB direction, the music output from the audio control device 1 can be replaced from the first music to the second music.

FIG. 8 is a diagram illustrating an example of a change in BPM during playback of each of the first song and the second song in the assist mode. Specifically, FIG. 8 shows a state in which the first music piece is played when the first operator 33A1 is operated in assist mode when the BPM of the first music piece is 100 and the BPM of the second music piece is 120. It is a figure explaining the change of BPM, and the change of BPM at the time of reproduction|regeneration of the 2nd music when 2nd operator 33B1 is operated.
When the operation mode of the acoustic control device 1 is the assist mode, the BPM setting unit 66 sets the BPM during playback of the first music according to the position of the first operator 33A1, as shown in FIG. The BPM at the time of reproduction of the second music piece is set according to the position of the operator 33B1. To be more specific, the BPM setting unit 66 sets the BPM of the first music piece and the second music piece according to the division result obtained by dividing the numerical value indicating the position of the first operator 33A1 by the numerical value indicating the position of the second operator 33B1. Set the BPM for each playback.

Here, the storage unit (not shown) stores the graph shown in FIG. 8 in advance. That is, the storage unit stores BPM change information indicating the BPM corresponding to the numerical value of the division result. Specifically, the storage unit stores, as BPM change information, a function that approaches the BPM of the second song as the numerical value of the division result becomes smaller, and approaches the BPM of the first song as the numerical value of the division result increases. . Note that the function stored in the storage unit as BPM change information may be a linear function as shown in FIG. 8, or may be a high-order function such as a quadratic function.
The volume adjustment section 65 adjusts the volume of the entire first music piece based on the position of the first controller 33A1, and adjusts the volume of the entire second music piece based on the position of the second controller 33B1. ing. Therefore, instead of the BPM change information, the storage unit (not shown) stores BPM change information indicating the BPM corresponding to the numerical value of the division result obtained by dividing the volume of the entire first song by the volume of the entire second song. You can.

Based on such BPM change information, the BPM setting unit 66 acquires the BPM corresponding to the above-mentioned division result, and sets the acquired BPM as the BPM of each song.
Therefore, for example, if the first operator 33A1 is arranged at the first end TA1 and the second operator 33B1 is arranged at the second end TB2, the BPM setting section 66 Let the BPM at the time of each reproduction be the BPM of the second music piece. In the example of FIG. 8, the playback BPM of each song is set to 120, which is the BPM of the second song.
On the other hand, for example, when the first operator 33A1 is arranged at the second end TA2 and the second operator 33B1 is arranged at the first end TB1, the BPM setting section 66 sets the first music piece and the second music piece. Let the BPM of each playback be the BPM of the first music piece. In the example of FIG. 8, the playback BPM of each song is set to 100, which is the BPM of the first song.

Then, as the first operator 33A1 is operated in the +DA direction or as the second operator 33B1 is operated in the -DB direction, the BPM of each song approaches the BPM of the first song. Furthermore, as the first operator 33A1 is operated in the -DA direction or as the second operator 33B1 is operated in the +DB direction, the BPM of each song approaches the BPM of the second song.

[Usefulness of assist mode]
Normally, when DJing, people select songs with relatively similar BPMs and mix them together to connect the songs. However, inexperienced users such as beginners who do not know the concept of BPM tend to select and mix their favorite songs, and may end up mixing songs with relatively different BPMs. In such a case, the BPM difference between the previous song and the next song tends to create a sense of discomfort.
On the other hand, by switching the operation mode of the audio control device 1 to the assist mode and operating the fader operator 51 or the operators 33A1 and 33B1, the BPM of each song can be made the same during reproduction. Therefore, it is possible to select and mix a favorite song without worrying about the BPM of the song, and the above-mentioned inexperienced user can immediately enjoy DJ play.

Furthermore, it is difficult for beginners to operate operators such as the tempo slider 34 to adjust the BPM of each song while performing the operation of mixing two songs using the fader operator 51 or the operators 33A1 and 33B1. The level of difficulty is high even for experienced users.
On the other hand, when the operation mode of the audio control device 1 is switched to the assist mode, music mixing and BPM adjustment can be performed simultaneously by simply operating the fader operator 51 or the operators 33A1 and 33B1. Therefore, the assist mode is useful not only for the above-mentioned inexperienced users but also for experienced users.

[Effects of the first embodiment]
The sound control device 1 according to the present embodiment described above has the following effects.
The sound control device 1 mixes the first music and the second music. The sound control device 1 includes a volume adjustment section 65 and a BPM setting section 66.
The volume adjustment unit 65 adjusts the volume of the first music piece and the volume of the second music piece according to the position of at least one of the fader operator 51, the first operator 33A1, and the second operator 33B1 operated by the user. Adjust the balance with the volume.
The BPM setting unit 66 sets the BPM when playing the first music and the BPM when playing the second music according to the position of the operator.
According to such a configuration, it is possible to simultaneously adjust the volume of each song and set the BPM during playback according to the user's operation on the operator. That is, by operating the controls, the user can not only adjust the volume of each song, but also adjust the BPM during playback. Therefore, the first music piece and the second music piece can be easily mixed without any discomfort.

In the sound control device 1, the volume control unit 65 adjusts the volume control unit 65 to the first level as the fader operator 51 is operated in the +DC direction from the first end TC1 to the second end TC2 in the operable range RC of the fader operator 51. The volume of the song is decreased and the volume of the second song is increased. The BPM setting unit 66 sets the BPM and the second BPM during playback of the first music piece as the fader operator 51 is operated in the direction from the first end TC1 to the second end TC2 in the operable range of the fader operator 51. To bring the BPM of a first piece of music closer to the BPM of a second piece of music when playing music.
According to such a configuration, when changing the music output from the audio control device 1 from the first music to the second music, the volume of the first music can be decreased by operating the fader operator 51 in the +DC direction. By increasing the volume of the second song, the BPM of the first song and the BPM of the second song can be brought closer to the BPM of the second song whose volume increases. Therefore, the first music and the second music can be easily mixed without any discomfort.

In the sound control device 1, when the fader operator 51 is placed at the second end TC2, the volume adjustment unit 65 sets the volume of the entire first song to the minimum volume V1min, and sets the volume of the entire second song to the second setting. The completed volume is set to V2st. The second set volume V2st is the maximum volume of the entire second music piece set by the second operator 33B1. When the fader operator 51 is placed at the second end TC2, the BPM setting unit 66 sets the BPM of the first music piece and the BPM of the second music piece to the BPM of the second music piece.
According to such a configuration, when the fader operator 51 is disposed at the second end TC2, the BPM of the second song is set as the BPM when the second song is played at which the volume becomes the second preset volume V2st. Can be set. Therefore, when replacing the first song with the second song, the second song can be played back at the BPM of the second song.

In the sound control device 1, when the fader operator 51 is placed at an intermediate position in the operable range RC, the BPM setting unit 66 sets each of the BPM during playback of the first music piece and the BPM during playback of the second music piece. Set to an intermediate value between the BPM of the first song and the BPM of the second song.
According to such a configuration, it is possible for the user to easily grasp the position where the playback BPM of the first music piece and the playback BPM of the second music piece are the intermediate value in the operable range of the fader operator 51. . Therefore, the operator can be easily operated when adjusting the BPM during playback.

In the audio control device 1, the operator operated by the user is the crossfader 5 having a slideable fader operator 51.
According to such a configuration, by operating the fader operator 51, the first music and the second music can be mixed without any discomfort. Therefore, the mixing operation between the first and second songs is easier than when operating the operator that adjusts the BPM when playing the first song and the operator that adjusts the BPM when playing the second song. can be implemented.

The sound control program executed by the arithmetic processing unit, which is a computer constituting the control unit 6, is recorded in a computer-readable manner, and causes the computer to function as the sound control device 1 described above.
By executing such a sound control program by the arithmetic processing unit of the sound control device 1, the above-described effects can be achieved.

[Second embodiment]
Next, a second embodiment of the present invention will be described.

Configured with 1 processor. That is, the arithmetic processing circuit is a computer.
The control section 6A has the same configuration as the control section 6 except that it includes a volume adjustment section 65A instead of the volume adjustment section 65 according to the first embodiment. That is, the control section 6A includes a first playback section 61, a second playback section 62, a position acquisition section 63, a mode switching section 64, a volume adjustment section 65A, and a BPM setting section 66.

[Configuration of volume control section]
When the operation mode of the sound control device is the normal mode, the volume adjustment section 65A functions similarly to the volume adjustment section 65 according to the first embodiment.
When the operation mode of the sound control device is the assist mode, unlike the volume adjustment unit 65 according to the first embodiment, the volume adjustment unit 65A adjusts the volume of each of the high frequency band and the medium frequency band of the first music, and the volume of the first music. The volume of the low frequency band of one song is individually adjusted, and the volume of each of the high frequency band and medium frequency band of the second song, and the volume of the low frequency band of the second song are individually adjusted. To be more specific, the volume adjustment section 65A adjusts the volume level of the high frequency band and medium frequency band of the first song, and the volume level of the low frequency band of the first song, thereby adjusting the volume level of the first song. Adjust the volume of each frequency band individually. The volume adjustment unit 65A adjusts the volume level of each frequency band of the second music by individually adjusting the volume level of each of the high frequency band and medium frequency band of the second music and the volume level of the low frequency band of the second music. Adjust the volume individually.

[Volume adjustment when operating the crossfader in assist mode]
FIG. 10 is a diagram showing changes in the volume level of each frequency band of the first song and changes in the volume level of each frequency band of the second song when the crossfader 5 is operated in the assist mode. On the horizontal axis of the graph shown in FIG. 10, numerical values indicating the relative positions of the fader operators 51 described above are set. Further, in FIG. 10, the set level H1lv and the set level H2lv are shown as the same value, but the set level H1lv and the set level H2lv do not necessarily have to be the same value. The same goes for the set levels M1lv and M2lv, and the same goes for the set levels L1lv and L2lv.
In the assist mode, the operable range RC of the fader operator 51 includes a first range RC1, a second range RC2, and a third range RC3, as shown in FIG.
The first range RC1 is a range between the first position PC1 and the second position PC2. The second position PC2 is set in the +DC direction with respect to the first position PC1.
The second range RC2 is a range between the second position PC2 and the third position PC3. The third position PC3 is set in the +DC direction with respect to the second position PC2.
The third range RC3 is a range between the third position PC3 and the fourth position PC4. The fourth position PC4 is set in the +DC direction with respect to the third position PC3.
In this embodiment, the first position PC1 is set at the first end TC1, and the fourth position PC4 is set at the second end TC2. The first range RC1 is 1/3 of the operable range RC from the first end TC1, and the second range RC2 is 1/3 of the operable range RC from the second position PC2. The third range RC3 is 1/3 of the operable range RC from the third position PC3.

When the operation mode is the assist mode and the fader operator 51 is arranged at the first end TC1, the volume adjustment section 65A adjusts the volume level of each wavelength band of the first music, as shown in FIG. Let the set levels of each frequency band of the first song be H1lv, M1lv, L1lv, and the volume level of each wavelength band of the second song be the minimum level of each frequency band of the second song H2min, M2min, L2min. As a result, the volume of the entire first music piece becomes the first set volume V1st, and the volume of the entire second music piece becomes the second minimum volume V2min.

When the operation mode is the assist mode and the fader operator 51 is arranged in the first range RC1, the volume adjustment section 65A sets the volume level of each wavelength band of the first music to the set levels H1lv, M1lv, L1lv, and while keeping the volume level of the low frequency band of the second song at the minimum level L2min, as the fader operator 51 is operated in the +DC direction, the volume level of each of the high frequency band and medium frequency band of the second song is adjusted. increase. That is, the volume level that changes in the first range RC1 is the volume level of the high frequency band and the volume level of the middle frequency band of the second music piece.
In the first range RC1, the volume level of the high frequency band of the second song is changed in the range from the minimum level H2min of the high frequency band of the second song to the preset level H2lv.
In the first range RC1, the volume level of the intermediate frequency band of the second song is changed in the range from the minimum level M2min of the intermediate frequency band of the second song to the preset level M2lv.

When the fader operator 51 is disposed at the second position PC2, the volume adjustment section 65A sets the volume level of each frequency band of the first music to the set levels H1lv, M1lv, L1lv, and sets the volume level of each frequency band of the first music to the low frequency band of the second music. While keeping the volume level of the second song at the minimum level L2min, the volume level of the high frequency band of the second song is set to a preset level H2lv, and the volume level of the middle frequency band of the second song is set to a preset level M2lv.

When the operation mode is the assist mode and the fader operator 51 is arranged in the second range RC2, the volume adjustment section 65A sets the volume level of the high frequency band of the first music to the preset level H1lv, The volume level of the middle frequency band of the song is set to the set level M1lv, the volume level of the high frequency band of the second song is set to the set level H2lv, and the volume level of the middle frequency band of the second song is set to the set level M2lv, As the fader operator 51 is operated in the +DC direction, the volume level of the low frequency band of the first song is decreased from the set level L1lv, and the volume level of the low frequency band of the second song is increased from the minimum level L2min. . That is, the volume level that changes in the second range RC2 is the volume level of the low frequency band of the first song and the volume level of the low frequency band of the second song.
In the second range RC2, the volume level of the low frequency band of the first song is changed in the range from the minimum level L1min of the low frequency band of the first song to the preset level L1lv.
In the second range RC2, the volume level of the low frequency band of the second song is changed in the range from the minimum level L2min of the low frequency band of the second song to the preset level L2lv.

The set level L1lv of the low frequency band of the first music and the set level L2lv of the low frequency band of the second music are the same, and the minimum level L1min of the low frequency band of the first music and the low frequency of the second music When the minimum band level L2min is the same, when the fader operator 51 is placed at the center position of the second range RC2, the volume adjustment section 65A adjusts the volume level of the low frequency band of the first song and the second song. Match the volume level of the low frequency band.
Therefore, depending on whether the fader operator 51 is operated in the +DC direction or -DC direction with respect to the center position of the second range RC2, the volume level of the low frequency band of the first song and the The magnitude relationships between the volume levels of the low frequency bands of the two songs are swapped, and in turn, the magnitude relationships between the volume levels of the low frequency bands of each song are swapped. That is, when the fader operator 51 is operated in the +DC direction with respect to the center position of the second range RC2, the volume of the low frequency band of the second song becomes larger than the volume of the low frequency band of the first song. On the other hand, when the fader operator 51 is operated in the -DC direction with respect to the center position of the second range RC2, the volume of the low frequency band of the first song becomes larger than the volume of the low frequency band of the second song. .
Note that the center position in the second range RC2 coincides with the center position in the operable range RC.

In the present embodiment, the volume level change rate of the low frequency band of the first song and the volume level change rate of the low frequency band of the second song in the second range RC2 are constant. Therefore, when the fader operator 51 is operated from the second position PC2 in the +DC direction, the volume level of the low frequency band of the first song decreases at a constant rate, and the volume level of the low frequency band of the second song decreases at a constant rate. Levels increase at a constant rate. Furthermore, when the fader operator 51 is operated from the third position PC3 in the -DC direction, the volume level of the low frequency band of the first song increases at a constant rate, and the volume level of the low frequency band of the second song increases. The level decreases at a constant rate.
However, the present invention is not limited to this, and the volume level change rate of the low frequency band of the first song and the volume level change rate of the low frequency band of the second song in the second range RC2 may not be constant. For example, when the fader operator 51 is operated in the +DC direction in the second range RC2, the volume level of the low frequency band of the first song may be lowered in a predetermined curve shape, and the low frequency band of the second song The volume level of the band may be increased in a predetermined curve. That is, the rate of change in the volume level of the low frequency band of each song may change according to the operation of the fader operator 51.

When the fader operator 51 is arranged at the third position PC3, the volume adjustment section 65A sets the volume level of the high frequency band of the first song to the set level H1lv, and sets the volume level of the middle frequency band of the first song. The volume level of the high frequency band of the second song is set to the set level H2lv, the volume level of the middle frequency band of the second song is set to the set level M2lv, and the volume level of the low frequency band of the first song is set to the set level M1lv. is set as the minimum level L1min, and the volume level of the low frequency band of the second music piece is set as the set level L2lv.

When the operation mode is the assist mode and the fader operator 51 is arranged in the third range RC3, the volume adjustment section 65A sets the volume level of the low frequency band of the first song to the minimum level L1min, and sets the volume level of the low frequency band of the first song to the minimum level L1min, With the volume levels of the high frequency band, medium frequency band, and low frequency band set at the preset levels H2lv, M2lv, and L2lv, as the fader operator 51 is operated in the +DC direction, the volume level of the high frequency band of the first song increases. is lowered from the set level H1lv, and the volume level of the middle frequency band of the first song is lowered from the set level M1lv. That is, the volume level that changes in the third range RC3 is the volume level of the high frequency band and the volume level of the middle frequency band of the first song.
In the third range RC3, the volume level of the high frequency band of the first song is changed in the range from the minimum level H1min of the high frequency band of the first song to the preset level H1lv.
In the third range RC3, the volume level of the intermediate frequency band of the first song is changed in a range from the minimum level M1min of the intermediate frequency band of the first song to the preset level M1lv.

When the fader operator 51 is placed at the fourth position PC4, that is, when the fader operator 51 is placed at the second end TC2, the volume adjustment section 65A adjusts the high frequency band and medium frequency of the first song. The respective volume levels of the band and low frequency band are set to minimum levels H1min, M1min, and L1min, and the respective volume levels of the high frequency band, medium frequency band, and low frequency band of the second song are set levels H2lv, M2lv, L2lv. . As a result, the volume of the entire first song becomes the first minimum volume V1min, the volume of the entire second song becomes the second set volume V2st, and the mixing from the first song to the second song is completed.

[Minimum level setting]
In the above description, the minimum levels H1min, M1min, L1min, H2min, M2min, and L2min of each wavelength band are set to 0 for convenience. However, the present invention is not limited to this, and at least one of the minimum levels H1min, M1min, L1min, H2min, M2min, and L2min may not be 0.
For example, the minimum levels H1min, M1min, L1min, H2min, M2min, and L2min may be set according to the values of the set levels H1lv, M1lv, L1lv, H2lv, M2lv, and L2lv.
In a more detailed example, if the set level H1lv of the high frequency band of the first song is 0 or more and 0.5 or less, the minimum level H1min is set to 0, and the set level H1lv exceeds 0.5 and is 1 or less. In this case, the minimum level H1min may be a value obtained by subtracting 0.5 from the set level H1lv. When the set levels M1lv, L1lv, H2lv, M2lv, L2lv are 0 or more and less than 0.5, the minimum levels M1min, L1min, H2min, M2min, L2min are similarly set.

FIG. 11 shows each frequency band of the first music when the set level L1lv of the low frequency band of the first music is 0.6 and the set level L2lv of the low frequency band of the second music is 0.5. FIG. 4 is a diagram showing changes in the volume level of the second song and changes in the volume level of each frequency band of the second song.
For example, when the low frequency band adjustment section 324 sets the preset level L1lv of the low frequency band of the first song to 0.6, as shown in FIG. The level may be set to 0.1.
Even in such a case, by operating the fader operator 51, the volume of the first music piece and the volume of the second music piece can be switched. In particular, by operating the fader operator 51 in the second range RC2, the volume of the low frequency band of the first song and the low frequency band of the second song can be adjusted regardless of the volume of the high frequency band and medium frequency band of each song. You can change the volume.
Note that the difference between the set level and the minimum level is not limited to 0.5, and can be changed as appropriate.

FIG. 12 is a diagram illustrating another example of a change in BPM during playback of each of the first music piece and the second music piece in the assist mode. Specifically, FIG. 13 shows the change in BPM during playback of each song when the crossfader 5 is operated in assist mode when the BPM of the first song is 100 and the BPM of the second song is 120. It is a figure which shows another example. Note that on the horizontal axis of the graph shown in FIG. 12, a numerical value indicating the relative position of the fader operator 51 described above is set.
As described in the first embodiment, the BPM setting unit 66 changes the BPM of each song during playback in the same way throughout the operable range RC in accordance with the operation of the fader operator 51. However, the present invention is not limited thereto; for example, as shown in FIG. Accordingly, the BPM during playback of each of the first music piece and the second music piece may be adjusted.

In this case, when the fader operator 51 is arranged at the first end TC1 (first position PC1), the BPM setting section 66 sets the BPM of the first music and the second music at the time of playback of each of the first music and the second music. The BPM of In the example of FIG. 12, the playback BPM of each song is set to 100, which is the BPM of the first song.
When the fader operator 51 is arranged in the first range RC1, the BPM setting unit 66 sets the BPM in the range between the BPM of the first song and the intermediate value between the BPM of the first song and the BPM of the second song. Depending on the position of the fader operator 51, the BPM of each piece of music is set. In the example of FIG. 12, the BPM of the first song is 100, and the intermediate value between the BPM of the first song and the BPM of the second song is 110, so the fader operator 51 is arranged in the first range RC1. If so, the BPM during playback of each song is set to a value greater than 100 and less than 110.

When the fader operator 51 is arranged at the second position PC2, the second range RC2, and the third position PC3, the BPM setting section 66 sets the BPM during playback of each of the first music piece and the second music piece to the above-mentioned intermediate value. Set to . In the example of FIG. 12, the BPM during playback of each song is set to 110.
When the fader operator 51 is arranged in the third range RC3, the BPM setting unit 66 sets the BPM of the first song according to the position of the fader operator 51 in the range between the above-mentioned intermediate value and the BPM of the second song. and the BPM at the time of reproduction of each of the second songs. In the example of FIG. 12, the BPM of the second song is 120, so the BPM of each song during playback is set to a value greater than 110 and less than 120.

When the fader operator 51 is arranged at the second end TC2 (fourth position PC4), the BPM setting unit 66 sets the BPM of each of the first music and the second music at the time of playback to the BPM of the second music. do. In the example of FIG. 12, the BPM during playback of each song is set to 120.
Note that although the rate of change in BPM during reproduction in the first range RC1 and the third range RC3 is constant in the example of FIG. 12, it does not have to be constant. For example, the rate of change may change as the fader operator 51 is operated in the ±DC direction.
In this way, when the BPM changes during playback of each song, the BPM setting section 66 adjusts the volume level of the high frequency band and medium frequency band according to the operation of the fader operator 51 by the volume adjustment section 65. You can adjust the BPM when playing music. Therefore, each song can be mixed naturally without any discomfort.

[Volume adjustment when operating the channel fader in assist mode]
Hereinafter, the volume adjustment of each song by the volume adjustment section 65A when the operation mode of the audio control device is the assist mode and the operators 33A1 and 33B1 of the respective channel faders 33A and 33B are operated will be described. Note that the content of the BPM settings at the time of playback by the BPM setting unit 66 of each song when operating each of the operators 33A1 and 33B1 in the assist mode is the same as that at the time of playback of each song by the BPM setting unit 66 described in the first embodiment. The settings are the same as those for BPM.

Further, when the operation mode of the sound control device 1 is the assist mode, the volume adjustment unit 65A adjusts the volume level of each frequency band of the second music according to the range in which the second operator 33B1 is located in the operable range RB. to adjust the volume of the second song.
As shown in FIG. 13, a predetermined position between the first end TA1 and the second end TA2 in the operable range RA of the first operator 33A1 is defined as a position PA1. The position PA1 can be set at ⅓ of the operable range RA from the second end TA2. The range from the first end TA1 to the position PA1 is defined as a first range RA1, and the range from the position PA1 to the second end TA2 is defined as a second range RA2.
Further, in the operable range RB of the second operator 33B1, a predetermined position between the first end TB1 and the second end TB2 is defined as a position PB1. The position PB1 can be set to ⅓ of the operable range RB from the second end TB2. The range from the first end TB1 to the position PB1 is defined as a first range RB1, and the range from the position PB1 to the second end TB2 is defined as a second range RB2.

[Volume adjustment in the first range of the channel fader]
As shown in FIG. 13, the volume adjustment unit 65A adjusts the volume level of each of the high frequency band and medium frequency band of the first music according to the position of the first operator 33A1 in the first range RA1, and Depending on the position of the second operator 33B1 in the range RB1, the volume level of each of the high frequency band and medium frequency band of the second music is adjusted.
Note that the first set volume V1st is set in advance based on the position of the first controller 33A1, and the second set volume V2st is set in advance based on the position of the second controller 33B1. shall be. For example, the first set volume V1st can be set to a volume corresponding to the position of the first operator 33A1 when the mode changeover switch 4 is pressed and the mode changeover section 64 switches the operation mode to the assist mode. . The second set volume V2st can be set to a volume corresponding to the position of the second operator 33B1 when the mode changeover switch 4 is pressed and the mode changeover section 64 switches the operation mode to the assist mode. However, the present invention is not limited to this, and the first set volume V1st may be set in advance by other methods or other operators. The same applies to the second set volume V2st.

When the first operator 33A1 is placed at the first end TA1 in the assist mode, the volume adjustment section 65A sets the volume level of each of the high frequency band, medium frequency band, and low frequency band of the first music to the minimum level H1min, M1min and L1min are set, and the volume of the entire first music piece is set to the first minimum volume V1min.
When the first operator 33A1 is arranged in the first range RA1, when the first operator 33A1 is operated, the volume adjustment section 65A adjusts the low frequency band of the first music, although not shown in FIG. As shown in FIG. 13, the volume level of the high frequency band of the first song is changed between the minimum level H1min and the preset level H1lv according to the position of the first controller 33A1, while keeping the volume level of the first music piece at the minimum level L1min. At the same time, the volume level of the middle frequency band of the first music piece is adjusted between the minimum level M1min and the preset level M1lv. That is, when the first operator 33A1 is operated in the +DA direction in the first range RA1, the volume adjustment section 65A increases the volume level of each of the high frequency band and the medium frequency band of the first song, and increases the volume level in the -DA direction. When operated, the volume level of each of the high frequency band and medium frequency band of the first song is reduced. As a result, the volume of the entire first song changes. Note that in the example of FIG. 13, the rate of change in the volume level of each of the high frequency band and medium frequency band of the first song is constant, but it does not have to be constant. For example, each rate of change may change as the first operator 33A1 is operated in the ±DA direction.

When the first controller 33A1 is placed at the position PA1, the volume adjustment unit 65 sets the volume level of the high frequency band of the first music while keeping the volume level of the low frequency band of the first music at the minimum level L1min. The level is set to H1lv, and the volume level of the middle frequency band of the first song is set to the set level M1lv.
In this way, the volume change of the first music piece when the first controller 33A1 is placed in the first range RA1 is the same as the volume change of the first music piece when the fader operator 51 is placed in the third range RC3. Same as change.

When the second operator 33B1 is placed at the first end TB1 in the assist mode, the volume adjustment unit 65A sets the volume level of each of the high frequency band, medium frequency band, and low frequency band of the second music to the minimum level H2min, M2min and L2min are set, and the volume of the entire second music piece is set to the second minimum volume V2min.
When the second operator 33B1 is arranged in the first range RB1, when the second operator 33B1 is operated, the volume adjustment section 65A adjusts the low frequency band of the second music, although not shown in FIG. As shown in FIG. 13, the volume level of the high frequency band of the second song is changed from the minimum level H2min to the preset level H2lv depending on the position of the second controller 33B1, while keeping the volume level of the second music set at the minimum level L2min. At the same time, the volume level of the middle frequency band of the second music piece is adjusted between the minimum level M2min and the preset level M2lv. That is, when the second operator 33B1 is operated in the +DB direction in the first range RB1, the volume adjustment section 65A increases the volume level of each of the high frequency band and the medium frequency band of the second song, and increases the volume level in the -DB direction. When operated, the volume level of each of the high frequency band and medium frequency band of the second music is reduced. As a result, the volume of the entire first song changes. Note that in the example of FIG. 13, the rate of change in the volume level of each of the high frequency band and medium frequency band of the second song is constant, but it does not have to be constant. For example, each rate of change may change as the second operator 33B1 is operated in the ±DB direction.

When the second controller 33B1 is placed at position PB1, the volume adjustment unit 65 sets the volume level of the high frequency band of the second music while keeping the volume level of the low frequency band of the second music at the minimum level L2min. The level is set to H2lv, and the volume level of the middle frequency band of the second song is set to the set level M2lv.
In this way, the volume change of the second music piece when the second controller 33B1 is placed in the first range RB1 is the same as the volume change of the second music piece when the fader operator 51 is placed in the first range RC1. Same as change.

[Volume adjustment in the second range of the channel fader]
The volume adjustment unit 65A adjusts the first music from the minimum level L1min to the preset level L1lv according to the position of the first operator 33A1 in the second range RA2 and the position of the second operator 33B1 in the second range RB2. The volume level of the low frequency band of the second song is adjusted between the minimum level L2min and the preset level L2lv.

Specifically, when the first operator 33A1 is placed in the second range RA2 and the second operator 33B1 is placed in the second range RB2, the volume adjustment unit 65A controls the first The numerical value indicating the position of the operator 33A1 and the numerical value indicating the position of the second operator 33B1 are converted. To be more specific, the volume adjustment unit 65A sets the acquired numerical value indicating the position of the first operator 33A1 to 0 when the first operator 33A1 is located at the position PA1, and sets the value to 0 when the first operator 33A1 is located at the position PA1, and sets the value indicating the position of the first operator 33A1 to 0 at the second end TA2. It is converted into a numerical value that becomes 1 when the child 33A1 is located. Similarly, the volume adjustment unit 65A sets the obtained numerical value indicating the position of the second operator 33B1 to 0 when the second operator 33B1 is located at the position PB1, and sets the value to 0 when the second operator 33B1 is located at the position PB1, and sets the value to 0 when the second operator 33B1 is located at the position PB1, Convert to a numerical value that becomes 1 when 33B1 is located.
Next, the volume control unit 65A divides the converted numerical value indicating the position of the first operator 33A1 by the converted numerical value indicating the position of the second operator 33B1, and obtains the numerical value of the division result.
Thereafter, the volume adjustment unit 65A obtains the volume level of the first music piece and the volume level of the second music piece that correspond to the numerical value of the division result.

FIG. 14 is a diagram showing an example of a change in the volume level of the low frequency band of each of the first music piece and the second music piece when the first operator 33A1 and the second operator 33B1 are operated in the assist mode. In other words, FIG. 14 is a diagram illustrating the contents of level change information stored in a storage section (not shown).
Here, the storage unit (not shown) stores the graph shown in FIG. 14 in advance. That is, the storage unit stores level change information indicating the volume level of the low frequency band of each song corresponding to the numerical value of the division result. To be more specific, the storage unit stores, as level change information indicating the volume level of the low frequency band of the first song, the smaller the numerical value of the division result approaches the minimum level L1min, and the larger the numerical value of the division result, the preset level. A function that approaches L1lv is memorized. The storage unit also stores, as level change information indicating the volume level of the low frequency band of the second music, the smaller the numerical value of the division result, the closer to the set level L2lv, and the larger the numerical value of the division result, the lower the set level L2min. It remembers the function it approaches. Note that the function stored in the storage unit as the level change information may be a linear function as shown in FIG. 14, or may be a high-order function such as a quadratic function.

Based on such level change information, the volume adjustment unit 65A acquires the volume level of the low frequency band of each song, and sets the volume level of the low frequency band of each song to the acquired volume level.
Note that when the respective operators 33A1 and 33B1 are arranged in the second ranges RA2 and RB2, the respective volume levels of the high frequency band and medium frequency band of the first music are set levels H1lv and M1lv, The respective volume levels of the high frequency band and medium frequency band are set levels H2lv and M2lv.
In this way, when the first operator 33A1 is arranged in the second range RA2 and the second operator 33B1 is arranged in the second range RB2, the volume change of each song is as follows: This is the same as the change in volume of each song when placed in RC2.

[Replacement of the first song and the second song in the output song]
When the operation mode of the sound control device 1 is the assist mode, the volume adjustment section 65A adjusts the volume level of each frequency band of the first music and the second music as described above. From this, by operating each of the operators 33A1 and 33B1 as follows, the volume of each frequency band of the first song and the volume of each frequency band of the second song can be adjusted in the same way as when operating the fader operator 51. You can change the volume.

For example, assume that the first operator 33A1 is arranged at the second end TA2, and the second operator 33B1 is arranged at the first end TB1. In this case, the volume of the entire first song is the first set volume V1st, and the volume of the entire second song is the second minimum volume V2min.
From this state, when only the second controller 33B1 is operated in the +DB direction, the second controller While 33B1 is located in the first range RB1, the volume level of the low frequency band of the second song remains at the minimum level L2min, and the volume level of each of the high frequency band and medium frequency band of the second song increases. Then, when the second operator 33B1 reaches position PB1, the volume level of the high frequency band of the second music becomes the set level H2lv, and the volume level of the middle frequency band of the second music becomes the set level M2lv. In this way, similarly to the case where the fader operator 51 is operated in the first range RC1, the volume of each of the high frequency band and medium frequency band of the second music piece can be adjusted.

When only the second controller 33B1 is operated from position PB1 in the +DB direction, the volume level of the high frequency band of the second song remains at the set level H2lv, and the volume level of the middle frequency band of the second song remains the set level M2lv. As shown in FIG. 14, the volume level of the low frequency band of the second song increases from the minimum level L2min, and the volume level of the low frequency band of the first song decreases from the preset level L1lv. Accordingly, the volume of the entire first song decreases from the first set volume V1st.
Then, when the second operator 33B1 reaches the second end TB2, since the first operator 33A1 is also arranged at the second end TA2, as shown in FIG. The volume level of the first music piece and the volume level of the low frequency band of the first music piece are both equal to each other.
After this, when only the first controller 33A1 is operated from the second end TA2 in the -DA direction, the volume level of the high frequency band of the first song remains at the set level H1lv, and the volume level of the middle frequency band of the first song remains the same. While the volume level remains at the set level M1lv, as shown in FIG. 14, the volume level of the low frequency band of the first song decreases, and the volume level of the low frequency band of the second song increases.
Then, when the first controller 33A1 reaches position PA1, the volume level of the low frequency band of the first music becomes the minimum level L1min, and the volume level of the low frequency band of the second music reaches the preset level L2lv. Become. Accordingly, the volume of the entire second music piece becomes the second set volume V2st. That is, the conditions for the volume of the entire second music to be the second preset volume V2st are that the second controller 33B1 is located at the second end TB2, and the first controller 33A1 is located at the position PA and the first It is arranged in range RA1 or first end TA1. Note that the conditions for the volume of the entire first music piece to be the first set volume V1st are also the same.

When the first operator 33A1 is operated in the -DA direction from the position PA1 while the second operator 33B1 is placed at the second end TB2, the volume level of the low frequency band of the first music is set to the minimum level L1min. As shown in the graph of the volume levels of the high frequency band and the medium frequency band of the first music piece shown on the left side of FIG. 13, the volume level of the high frequency band and the medium frequency band of the first music piece decreases.
When the first controller 33A1 reaches the first end TA1, the volume level of the high frequency band of the first song becomes the minimum level H1min, the volume level of the middle frequency band of the second song becomes the minimum level M1min, and the first The volume of the entire music becomes the first minimum volume V1min. In this way, similarly to the case where the fader operator 51 is operated in the third range RC3, the volume level of each of the high frequency band and medium frequency band of the first music piece can be adjusted.

As described above, by operating the second controller 33B1 in the second range RB2 and operating the first controller 33A1 in the second range RA2, the volume level of the low frequency band of the first music piece is lowered. , the volume level of the low frequency band of the second song can be increased. That is, in a state where the volume levels of the high frequency band and medium frequency band of the first song are set to preset levels H1lv and M1lv, and the volume levels of the high frequency band and medium frequency band of the second song are set to preset levels H2lv and M2lv, By increasing or decreasing the volume levels of the low frequency bands of the first music piece and the second music piece, it is possible to replace the volume levels of the low frequency bands of the first music piece and the second music piece.

[Effects of second embodiment]
The sound control device according to the present embodiment described above can have the same effects as the sound control device 1 according to the first embodiment described above, and can also have the following effects.
In the sound control device according to the present embodiment, the operable range RC of the fader operator 51 includes a first range RC1, a second range RC2, and a third range RC3.
The first range RC1 is a range between the first position PC1 and the second position PC2. The second position PC2 is located in the +DC direction with respect to the first position PC1. The +DC direction corresponds to a first operation direction from the first end TC1 to the second end TC2.
The second range RC2 is a range between the second position PC2 and the third position PC3. The third position PC3 is located in the +DC direction with respect to the second position PC2.
The third range RC3 is a range between the third position PC3 and the fourth position PC4. The fourth position PC4 is located in the +DC direction with respect to the third position PC3.
As the fader operator 51 is moved in the +DC direction, the BPM setting unit 66 brings the BPM of the first music piece and the second music piece closer to the BPM of the second music piece. The BPM setting unit 66 sets the BPM during playback of the first music piece and the BPM during playback of the second music piece as the first operator 33A1 is moved in the -DA direction or as the second operator 33B1 is moved in the +DB direction. The time BPM is brought closer to the BPM of the second song.
According to such a configuration, it is possible to change the BPM of each song during playback so that it approaches the BPM of the second song. Therefore, the operation for bringing the BPM of each song closer to the BPM of the second song during reproduction can be simplified.

In the sound control device according to the present embodiment, when the fader operator 51 is arranged in the second range RC2, the BPM setting unit 66 does not change the BPM when playing the first song and the BPM when playing the second song. .
According to such a configuration, when the fader operator 51 is arranged in the second range RC2 where each of the first music piece and the second music piece can be easily heard, the BPM is not changed when each music piece is played. This allows the first music and the second music to be easily mixed without any discomfort.

In the sound control device according to the present embodiment, when the fader operator 51 is arranged in the second range RC2, the volume adjustment section 65A is configured to control the high frequency band of the first song, the middle frequency band of the first song, and the second song. When the volume levels of the high frequency band and the medium frequency band of the second song are at the set levels H1lv, M1lv, H2lv, M2lv, as the fader operator 51 is operated in the +DC direction, the volume level of the first song becomes lower. While decreasing the volume level of the frequency band, the volume level of the low frequency band of the second music piece is increased.
As described above, the set level H1lv is the volume level set by the user using the high frequency band adjustment section 322 of the first channel operation section 3A as the maximum level of the high frequency band of the first song. The same applies to the set levels M1lv, H2lv, and M2lv.
Further, the +DC direction corresponds to the first operation direction.
According to such a configuration, the total volume of the low frequency components of each of the first music piece and the second music piece can be maintained at the same level as the total volume of each low frequency component before mixing. Thereby, compared to the case where the entire first music piece and the entire second music piece are mixed without adjusting the frequency, it is possible to suppress the low frequency components from being heard strongly during the mixing of the first music piece and the second music piece. Moreover, since each song is played at an intermediate BPM, the first song and the second song can be mixed without any discomfort.

In the acoustic control device according to this embodiment, the first position PC1 is the first end TC1, and the fourth position PC4 is the second end TC2. The first range RC1 is 1/3 of the operable range RC from the first end TC1. The second range RC2 is 1/3 of the operable range RC from the second position PC2. The third range RC3 is 1/3 of the operable range RC from the third position PC3.
According to such a configuration, the user can intuitively grasp the respective positions of the first range RC1, the second range RC2, and the third range RC3. Therefore, it is possible to easily operate the fader operator 51 when mixing the first music and the second music.

[Third embodiment]
Next, a third embodiment of the present invention will be described.

In other words, the operation determination unit 67 determines whether the time from one end to the other end of the first end TC1 and the second end TC2 is less than a predetermined time. Specifically, the operation determination unit 67 determines whether a predetermined period of time has elapsed since the fader operator 51 located at one end of the first end TC1 and the second end TC2 was operated toward the other end. In the meantime, it is determined whether the other end has been reached.

[Configuration of playback control unit]
The playback control unit 68 controls the playback state of the first music piece by the first playback unit 61 and the playback state of the second music piece by the second playback unit 62 in accordance with the operation of the fader operator 51. Specifically, the playback control unit 68 controls the respective playback positions of the first music piece and the second music piece based on the determination result by the operation determination unit 67.

When the playback control unit 68 determines that the speed of the fader operator 51 when reaching the other end from one end of the first end TC1 and the second end TC2 is equal to or higher than a predetermined value. In this case, the following first regeneration control process is executed, and if the speed is determined to be less than a predetermined value, the following second regeneration control process is executed.
In other words, the reproduction control unit 68 determines that the arrival time, which is the time taken to reach the other end from one end of the first end TC1 and the second end TC2, is equal to or longer than the predetermined time. If the arrival time is determined to be less than the predetermined time, the following first reproduction control process is executed, and if it is determined that the arrival time is less than the predetermined time, the following second reproduction control process is executed.

Specifically, the playback control unit 68 controls the playback control unit 68 when the fader operator 51 that is away from one of the first end TC1 and the second end TC2 reaches the other end in less than a predetermined time. executes the following second regeneration control process, and if the other end has not been reached even after a predetermined time has elapsed, executes the following first regeneration control process.
In any of the playback control processes, if the fader operator 51 is placed at the first end TC1 or the second end TC2, the playback control unit 68 controls the first music piece by the first playback unit 61. and the reproduction of the second music piece by the second reproduction section 62 are not controlled.

[First playback control process]
The first playback control process is a process performed when the fader operator 51 is slowly operated from one end of the first end TC1 and the second end TC2 to the other end. In the following description, a case will be described in which the fader operator 51 is operated from the first end TC1 to the second end TC2.
When the fader operator 51 is operated from the first end TC1 in the +DC direction, the playback control unit 68 moves the playback position of the first song to a predetermined first playback position, and moves the playback position of the second song to a predetermined first playback position. to a predetermined third playback position. Note that if the second playback section 62 has stopped playing the second song, the playback control section 68 causes the second playback section 62 to start playing the second song.

When the playback position of the first song moves to the first playback position, the playback control unit 68 loops between the first playback position and a predetermined second playback position that is a playback position after the first playback position. Let it play. Further, when the playback position of the second song moves to the third playback position, the playback control unit 68 controls the playback position between the third playback position and a predetermined fourth playback position that is a playback position after the third playback position. play in a loop. That is, the playback position of the second music piece moved when the fader operator 51 is operated from the first end TC1 in the +DC direction is the third playback position, which is the playback position before the fourth playback position. .
When the fader operator 51 reaches the second end TC2, the playback control section 68 cancels the loop playback of the first song by the first playback section 61, and causes the second playback section 62 to stop the loop playback of the second song. unlock.
This makes it possible to replace the first song with the second song and to play the second song at the fourth playback position.

[Specific example of first playback control process]
FIG. 16 is a diagram illustrating an example of the first reproduction control process by the reproduction control section 68. Note that in FIG. 16, "Breakdown" is written as "Break".
Next, a specific example of the first reproduction control process will be described with reference to FIG. 16.
In the example of FIG. 16, the first song and the second song each include intro (Intro), breakdown 1 (Breakdown1), buildup 1 (Buildup1), drop 1 (Drop1), breakdown 2 (Breakdown2), It is a song in which the song components are connected in the order of Buildup 2, Drop 2, and Outro. In the example of FIG. 16, the outro start position is set as the first playback position of the first song, and the outro end position, that is, the end position of the first song, is set as the second playback position of the first song. . In the example of FIG. 16, a position in the middle of build-up 1 is set as the third playback position of the second song, and a start position of drop 1 is set as the fourth playback position of the second song.

For example, as shown in the first row from the top of FIG. The reproduction of the second music piece by the second reproduction unit 62 is not controlled. Therefore, the first music piece is played back by the first playback unit 61 at the BPM of the first music piece.
As shown in the second row from the top of FIG. 16, when the fader operator 51 is operated from the first end TC1 in the +DC direction, the playback control unit 68 changes the playback position PP1 of the first song to the outro start position. (first playback position), and also moves the playback position PP2 of the second music piece to a position in the middle of build-up 1 (third playback position). As described above, when the reproduction of the second music piece is stopped, the reproduction control unit 68 causes the second reproduction unit 62 to start playing the second music piece.

As shown in the third row from the top of FIG. 16, when the playback position PP1 of the first song moves to the outro start position of the first song, the playback control unit 68 controls the outro start position of the first song and the outro start position of the first song. The first playback unit 61 is caused to repeatedly play back the music portion between the ending position (second playback position). At the same time, when the playback position PP2 of the second song moves to a position in the middle of build-up 1, the playback control unit 68 controls the position in the middle of build-up 1 of the second song and the start position of drop 1 (fourth playback position ) is caused to be repeatedly played back by the second playback section 62.

As shown in the fourth row from the top of FIG. 16, when the fader operator 51 is placed at the second end TC2, the playback control unit 68 cancels the repeat playback of the first song and the repeat playback of the second song. do. As a result, the playback of the first music piece by the first playback unit 61 ends when the playback of the outro of the first music piece ends, and the playback of the second music piece by the second playback unit 62 continues, and after a while. Drop 1 of the second song is played. As described above, when the fader operator 51 is placed at the second end TC2, the volume adjustment section 65 sets the volume of the entire first song to the first minimum volume V1min, and sets the volume of the entire second song to the first minimum volume V1min. The volume is set to the second set volume V2st. Further, the BPM setting unit 66 sets the BPM of each song at the time of reproduction to the BPM of the second song.

The case where the fader operator 51 is operated from the first end TC1 to the second end TC2 has been described above. However, the same applies when the fader operator 51 is operated from the second end TC2 to the first end TC1.
That is, when the fader operator 51 is operated from the second end TC2 in the -DC direction, the playback position PP2 is moved to the first playback position of the second song, and then the first playback position and the second playback position are moved. The music part between is played repeatedly, and after the playback position PP1 is moved to the third playback position of the first music, the music part between the third playback position and the fourth playback position is played repeatedly. . Then, when the fader operator 51 is placed at the first end TC1, the playback control section 68 cancels the repeat playback of each song.
In this way, the playback position of the first music piece and the playback position of the second music piece are controlled in accordance with the operation from the first end TC1 and the second end TC2 of the fader operator 51. Accordingly, it is possible to mix the first music piece and the second music piece naturally.

[Play music when reaching the end]
When the fader operator 51 operated in the +DC direction reaches the second end TC2, the playback control unit 68 described above controls the reproduction of the music part between the third playback position and the fourth playback position in the second music piece. I decided to cancel repeat playback. In other words, although repeat playback is canceled for the second music piece, playback continues from the playback position at the time when the fader operator 51 reaches the second end TC2. However, the reproduction control unit 68 may implement one of the following first pattern and second pattern.

In the first pattern, the playback position PP2 of the second music piece is moved to the fourth playback position at the timing when the fader operator 51 reaches the second end TC2. In the example of FIG. 16, since drop 1 of the second song is played at the timing when the volume of the entire first song reaches the first minimum volume V1min, it is possible to naturally replace the first song with the second song.
In the second pattern, if the playback position PP2 of the second music piece at the timing when the fader operator 51 reaches the second end TC2 has not reached the bar break, the timing at which the playback of the current bar ends is determined. , the playback position PP2 is moved to the fourth playback position. In the example of FIG. 16, the playback position PP2 of the second song is moved to drop 1 at bar breaks, so each song can be mixed naturally so that sudden changes in composition do not occur.

[Second playback control process]
The second playback control process is a process performed when the fader operator 51 is instantaneously operated from one end of the first end TC1 and the second end TC2 to the other end. Specifically, in the second playback control process, when the fader operator 51 is momentarily operated from the first end TC1 to the second end TC2, the second playback control process changes the playback position of the second song to the fourth end of the second song. When the player moves to the playback position and momentarily operates from the second end TC2 to the first end TC1, the playback position of the first music piece is moved to the fourth playback position of the first music piece. In this case, the first minimum volume V1min is set as the volume of the entire first music piece by the volume adjustment unit 65, so the first music piece is not output.
In the case where the second music piece shown in FIG. 16 is played back by the second playback unit 62 and the second playback control process is executed by the playback control unit 68, the playback position of the first music piece is not changed; The playback position of the second song is moved to the start position of drop 1. Note that if the second playback section 62 has stopped playing the second song, the playback control section 68 causes the second playback section 62 to start playing the second song. Note that, when the fader operator 51 reaches the second end TC2, the overall volume of the first music piece becomes the minimum value and the overall volume of the second music piece becomes the maximum value by the above-mentioned volume adjustment section 65A. Furthermore, the BPM setting unit 66 sets the BPM of each song during playback to the BPM of the second song.
With such second playback control processing, when instantly switching from the first song to the second song, the chorus of the second song can be instantly played back.

[Configuration of position setting section and position selection section]
The position setting unit 69 shown in FIG. 15 sets points that can be set at the first playback position, the second playback position, the third playback position, and the fourth playback position for each song according to the user's operation. An example of such a point is a cue. Further, for example, the point may be the start position of each component included in the song. Note that, as described above, the constituent elements are constituent elements such as an intro, a drop, and an outro.
The position selection unit 70 functions when the operation mode of the acoustic control device is the assist mode. The position selection unit 70 selects a first playback position, a second playback position, a third playback position, and a fourth playback position of each song from the points set by the position setting unit 69 according to the user's operation. Each playback position selected by the position selection unit 70 is used in the first playback control process and the second playback control process by the playback control unit 68 described above.
The position setting section 69 and the position selection section 70 allow the user to set and select each playback position at an arbitrary position.

Furthermore, the acoustic control device of the present invention may include only the assist mode as the operation mode. Furthermore, the sound control device of the present invention includes a plurality of operators, and when one of the plurality of operators is operated, the volume adjustment units 65, 65A and the BPM setting unit 66 are set to the normal mode. When other operators are operated, the volume adjustment sections 65, 65A and the BPM setting section 66 may function in an assist mode.

In each of the above embodiments, the BPM of the first song is the adjusted BPM when playing the first song when the BPM when playing the first song is adjusted by the first tempo slider 34A; If the BPM during playback of the first song is not adjusted, it is determined that the BPM is the BPM of the original song of the first song. Similarly, if the BPM of the second song is adjusted by the second tempo slider 34B, the BPM of the second song is the adjusted BPM of the second song. If the BPM is not adjusted during playback, it is assumed that the BPM is that of the original song of the second song. However, the BPM of the first song is not limited to this, and may be the BPM of the original song of the first song even if the BPM during playback of the first song is adjusted by the first tempo slider 34A. Similarly, the BPM of the second song may be the BPM of the original song of the second song even if the BPM during reproduction of the second song is adjusted by the second tempo slider 34B.

In each of the embodiments described above, when the fader operator 51 is placed at an intermediate position in the operable range RC, the BPM setting unit 66 sets the BPM of each of the first music piece and the second music piece to the above intermediate value during reproduction. However, the present invention is not limited to this, and the position of the fader operator 51 when the volume of the low frequency band of each song becomes the same does not necessarily have to be an intermediate position in the operable range RC.
In the second embodiment, the position of the fader operator 51 when the volume adjustment unit 65A makes the volume of the low frequency band of the first song the same as the volume of the low frequency band of the second song is not necessarily within the operable range. It does not have to be an intermediate position in RC.

Further, when the fader operator 51 is placed at the second end TC2, the BPM setting unit 66 sets the BPM when playing the first song and the BPM when playing the second song to the BPM of the second song. did. However, the present invention is not limited thereto, and when the fader operator 51 is disposed at the second end TC2, it is sufficient that the ratio of the volume of the second music piece to the output volume is maximized. Further, when the volume of the first song is the minimum value, the BPM setting unit 66 does not need to set the BPM during reproduction of the first song to the BPM of the second song.

In the second embodiment, the operable range RC includes the first range RC1, the second range RC2, and the third range RC3. In the example shown in FIG. 12, in the first range RC1, the BPM setting unit 66 sets the BPM at the time of reproduction of the first music piece and the BPM at the time of reproduction of the second music piece according to the position of the fader operator 51. It is assumed that the setting range is from the BPM of the song to the intermediate value between the BPM of the first song and the BPM of the second song. In the second range RC2, the BPM setting unit 66 does not change the BPM when playing the first song and the BPM when playing the second song. In the third range RC3, the BPM setting unit 66 sets the BPM when playing the first song and the BPM when playing the second song in a range from the above-mentioned intermediate value to the BPM of the second song.
However, the present invention is not limited to this, and the BPM setting unit 66 may change the BPM of each of the first music piece and the second music piece during reproduction also in the second range RC2. At this time, the BPM setting unit 66 may change the BPM during playback of each of the first music piece and the second music piece at a rate of change different from that in the first range RC1 and the third range RC3.
Further, for example, a part of the first range RC1 and a part of the second range RC2 may overlap with each other, and a part of the second range RC2 and a part of the third range RC3 may overlap with each other. .

In the second embodiment, when the fader operator 51 is arranged in the first range RC1, the volume adjustment section 65A controls the high frequency band of the first song, the middle frequency band of the first song, and the low frequency band of the first song. The fader operator 51 is operated in the +DC direction in a state where the volume level of each band is the set level H1lv, M1lv, L1lv, and the volume level of the low frequency band of the second music is the minimum level L2min. The volume level of each of the high frequency band and the medium frequency band of the second song is increased as the frequency increases. When the fader operator 51 is arranged in the second range RC2, the volume adjustment section 65 adjusts the volume levels of the high frequency band of each song and the medium frequency band of each song to the preset levels H1lv, M1lv, H2lv, M2lv. In this state, as the fader operator 51 is operated in the +DC direction, the volume level of the low frequency band of the first song is decreased, and the volume level of the low frequency band of the second song is increased. When the fader operator 51 is arranged in the third range RC3, the volume adjustment section 65 adjusts the volume level of each of the high frequency band, medium frequency band, and low frequency band of the second music to the preset levels H2lv, M2lv, L2lv. And in a state where the volume level of the low frequency band of the first song is the minimum level L1min, as the fader operator 51 is operated in the +DC direction, the high frequency band of the first song and the inside of the first song are The idea is to reduce the volume level of each frequency band.
However, the present invention is not limited to this, and the operable range RC may be divided into more ranges. For example, a range for increasing/decreasing the volume level of the high frequency band of the first song and a range for increasing/decreasing the volume level of the medium frequency band of the first song may be provided separately from each other. Similarly, the range for increasing/decreasing the volume level of the high frequency band of the second song and the range for increasing/decreasing the volume level of the medium frequency band of the second song may be provided separately from each other.

In the second embodiment, the first range RC1 is 1/3 of the operable range RC from the first end TC1, and the second range RC2 is 1/3 of the operable range RC from the second position PC2. 3, and the third range RC3 is 1/3 of the operable range RC from the third position PC3. In other words, each of the ranges RC1 to RC3 is an equally divided range in the operable range RC. However, the present invention is not limited thereto, and one of the first range RC1, second range RC2, and third range RC3 may be larger than the other ranges.

In the second embodiment, in the second range RC2 in which the volume of each of the first song and the second song is adjusted in the assist mode, the high frequency band of the first song, the middle frequency band of the first song, the middle frequency band of the second song, It is assumed that the respective volume levels of the high frequency band and the medium frequency band of the second song are maintained at the preset levels H1lv, M1lv, H2lv, and M2lv. However, the present invention is not limited to this, and the volume level of each of the high frequency band of the first song, the medium frequency band of the first song, the high frequency band of the second song, and the medium frequency band of the second song may be set at a predetermined volume level. May be maintained. Further, for example, when the fader operator 51 is operated in the +DC direction, the volume level of each of the high frequency band of the second song and the medium frequency band of the second song reaches the preset levels H2lv, M2lv. The volume level of the low frequency band of the first music piece may start to increase, and the volume level of each of the high frequency band and the middle frequency band of the first music piece may decrease before the volume level of the low frequency band of the first music piece reaches the minimum level L1min.

The volume of the entire song was set to the first minimum volume V1min. However, the position of the fader operator 51 when the volume of the entire first song reaches the first minimum volume V1min when the fader operator 51 is operated in the +DC direction may not be at the second end TC2. The position may be in the -DC direction relative to the second end TC2. Similarly, the position of the fader operator 51 when the volume of the entire second song reaches the second minimum volume V2min when the fader operator 51 is operated in the -DC direction does not have to be at the first end TC1. Often, the position may be in the +DC direction relative to the first end TC1.
Furthermore, when the fader operator 51 reaches the first end TC1 in the operable range RC, the volume of the entire second music piece does not have to be set to the second minimum volume V2min, and when the fader operator 51 reaches the second end TC2. Furthermore, the volume of the entire first music piece may not be set to the first minimum volume V1min.
The same applies when the first operator 33A1 and the second operator 33B1 are operated at the first end TA1, TB1 and the second end TA2, TB2.

In each of the above embodiments, when the fader operator 51 is further operated in the +DC direction from the third position PC3 where the volume level of the low frequency band of the first song reaches the minimum level L1min, the high frequency band and medium frequency of the first song I decided to lower the volume level of each band. However, the present invention is not limited to this, and as described above, when the fader operator 51 is operated in the +DC direction from a position in the -DC direction relative to the third position PC3, not only the volume level of the low frequency band of the first song but also , the volume level of each of the high frequency band and medium frequency band of the first music may be reduced. The same applies to the volume level of each frequency band of the second music, and the same applies when the first operator 33A1 and the second operator 33B1 are operated.

a third range between the third position and a fourth position located in the first operating direction with respect to the third position;
The BPM setting unit brings the BPM of the first music piece and the second music piece closer to the BPM of the second music piece as the operator is moved in the first operation direction.
According to such a configuration, it is possible to change the BPM of each song during playback so that it approaches the BPM of the second song. Therefore, the operation for bringing the BPM of each song closer to the BPM of the second song during reproduction can be simplified.

[6] In the sound control device according to [5],
The BPM setting unit does not change the BPM at the time of reproduction of the first music and the BPM at the time of reproduction of the second music, when the operator is arranged in the second range.
According to such a configuration, when the controls are arranged in the second range where each of the first music piece and the second music piece can be easily heard, the BPM of the first music piece and the second music piece can be easily heard by not changing the BPM. To easily mix one song and a second song without feeling any discomfort.

[7] In the sound control device according to [5] or [6],
When the operator is arranged in the second range, the volume adjustment section includes a high frequency band of the first music, a medium frequency band of the first music, a high frequency band of the second music, and a high frequency band of the second music. While the volume level of each of the medium frequency bands is at the maximum level, as the operator is operated in the first operation direction, the volume level of the low frequency band of the first music piece is decreased, and the volume level of the low frequency band of the first music is decreased, 2 Increase the volume level of the low frequency band of the song.
According to such a configuration, the total volume of the low frequency components of each of the first music piece and the second music piece can be maintained at the same level as the total volume of each low frequency component before mixing. Thereby, compared to the case where the entire first music piece and the entire second music piece are mixed without adjusting the frequency, it is possible to suppress the low frequency components from being heard strongly during the mixing of the first music piece and the second music piece. Furthermore, since each song is played at an intermediate BPM, the first song and the second song can be mixed without any discomfort.

[8] In the sound control device according to any one of [5] to [7],
the first position is the first end;
the fourth position is the second end;
The first range is 1/3 of the operable range from the first end,
The second range is 1/3 of the operable range from the second position,
The third range is one third of the operable range from the third position.
According to such a configuration, the user can intuitively grasp the respective positions of the first range, the second range, and the third range. Therefore, it is possible to easily operate the operator when mixing the first music and the second music.

[9] In the sound control device according to any one of [1] to [8],
The operator is a crossfader having a slideable fader operator.
According to such a configuration, by operating the operator, the first music piece and the second music piece can be mixed without any discomfort. Therefore, the mixing operation between the first and second songs is easier than when operating the operator that adjusts the BPM when playing the first song and the operator that adjusts the BPM when playing the second song. can be implemented.

[10] The sound control program is recorded in a computer-readable manner and causes the computer to function as the sound control device according to any one of [1] to [9].
By causing a computer to execute such a sound control program, the same effects as the above-described sound control device can be achieved.
