And a mixing section 10 that mixes _B with each other.

The operation of each of the following embodiments is executed by the mixing device having the above configuration. (II) First Embodiment Next, a first embodiment corresponding to the invention described in claims 1, 3 and 4 will be described with reference to FIGS. 2 and 3.

First, the operation of the first embodiment will be described with reference to FIG. The operation shown in FIG. 2 is mainly shown in FIG.
In the first CPU3 and the second CPU4.

First, it is judged whether or not the mixing mode for instructing the start of mixing of the present invention is designated on the operation section 5 (step S1). When the mixing mode is not designated (step S1; NO), it stands by until it is designated, and when the mixing mode is designated (step S1; YES), the process proceeds to step S2.

Next, in step S2, the reproduction of the music (song) as the main sound is temporarily stopped (paused).
Next, in step S3, a sound effect suitable for the music posed in step S2 is designated. This designation is executed by the listener instructing the operation unit 5. The process in step S3 is executed when a plurality of types of sound effects are recorded on the CD single 2 '.

When the sound effect is designated, next, in step S4, a portion of the sound effect to be reproduced is selected. This selection is executed by the selection device 6, and more specifically, for example, a reproduction start time in the sound effect (elapsed time from the beginning of the sound effect) is selected by a random number.

In addition to this, as a method of selecting the reproduction start position, 1) subcode data as subcode information (corresponding to a sound effect) by a random number is recorded together with the sound effect on the CD single 2 '. 2) A method of selecting the address of the reproduction start position in 2) The address of the paused position in the paused music (the address included in the subcode data as the subcode information recorded on the compact disc 1'with the music) is transmitted as the transmission signal S. _The first CPU3 to the second _C as C
There is a method of transmitting to the PU 4 and inverting the transmitted address in the selection device 6 to calculate an inverted address, and starting reproducing a sound effect from a position on the CD single 2'corresponding to this inverted address.

When the reproduction start time (or reproduction start address) of the sound effect is selected in step S4, next,
The reproduction of the sound effect is started from the position of the subcode data as the second subcode information corresponding to the selected reproduction start time (or reproduction start address) (step S5).

Next, when the fact that the reproduction of the sound effect is started is transmitted from the second CPU 4 to the first CPU 3 as the transmission signal S _C , the first CPU 3 activates the timer included in the first CPU 3 to start the sound effect. It is measured whether or not a predetermined time has elapsed from the time (step S6). And
If the predetermined time has not elapsed (step S6; N
O), waits until the predetermined time elapses, and if the predetermined time elapses (step S6; YES), the first C
The PU 3 outputs the main sound control signal S ₁ to the first reproduction device 1 in order to cancel the pause of the main sound and start the reproduction. Then, the first reproduction device 1 starts reproduction of music based on the main sound control signal S ₁ (step S
7).

After that, the reproduction of the music is continued, and it is judged whether or not the music is completed (step S8). If not completed (step S8; NO), the reproduction is continued as it is. If it is finished (step S8; YES), it is then determined whether or not an instruction indicating the end of the mixing mode has been input at the operation unit 5 (step S9), and if there is no input indicating the end (step S9). ; NO), Step S to perform the mixing operation for the next music (song)
Return to 2. When there is an instruction to end the mixing mode (step S9; YES), the process ends.

Here, the start of reproduction of the sound effect and music (song) executed in steps S4 to S7 will be described in detail with reference to FIG. Playback start time (or playback start address) of the sound effect selected in step S4
When the sound effect is started to be reproduced (see reference numeral A in FIG. 3), the fact that the reproduction of the sound effect is started is the second transmission signal S _C.
The first CPU 3 is transmitted from the CPU 4. And the first C
The PU 3 activates the built-in timer from the timing of starting the reproduction of the sound effect. Then, when a preset predetermined time elapses, the control signal S ₁ is transmitted from the first CPU 3 to the first reproducing device 1 to start the reproduction of the music, and the reproduction of the music is started (see symbol B in FIG. 3). .

In the present embodiment, the time lag between the start of sound effect reproduction and the start of music reproduction (predetermined time in FIG. 3) is constant, and reproduction of the sound effect is started from which part of the sound effect. Is randomly selected by the selection device 6.

As shown in FIG. 3, when the reproduction level of the sound effect is gradually increased, the volume control signal S ₃ for controlling the level of the sound effect signal S _B in the volume 9 is output from the second CPU 4. It is transmitted to the volume 9 (see the dotted line in FIG. 1). In this case, the listener and controls the reproduction level (Fig. 3 reference numeral R _M reference) Volume 8 song playback level when the output is a constant playback level (sound effect sound effects. Figure 3 and thus it is controlled by the volume 9 code reference R _B). Then, the time from the start of the reproduction of the sound effect until a certain level is reached is the second CPU
Controlled by 4.

After the start of the reproduction of the music, the sound effect may be set to a constant level as shown in FIG. 3 or may be changed to a predetermined level (for example, the level is lowered so as to fade out). May be.

Further, when the reproduction of the sound effect is completed before the end of the music, the reproduction of the sound effect may be ended as it is, or the same sound effect may be repeatedly reproduced until the end of the music. It is also possible to continue playing the sound.

Further, in the above-mentioned first embodiment, the music is reproduced after a lapse of a predetermined time after the reproduction of the sound effect is started. However, conversely, depending on the kind of the music and the sound effect, It is also possible to start playing the music first and then start playing the sound effect after a lapse of a predetermined time.

According to the first embodiment described above, the sound effect is reproduced from a different position each time, and further,
The reproduction start timing of the song and the reproduction start timing of the sound effect can be different. (III) Second Embodiment Next, a second embodiment corresponding to the invention described in claim 2 will be described with reference to FIG.

In the first embodiment, when performing the mixing operation, in step S2 of FIG.
Regardless of the reproduction state of the music as the main sound (which part of one music is being reproduced), the music is once stopped and then the mixing operation is executed.

On the other hand, in the second embodiment, the reproduction of the music is always started from the beginning of the music (the beginning of one music). The operation of the second embodiment will be described with reference to FIG. In FIG. 4, the same operations as those in the first embodiment shown in FIG. 2 are designated by the same step numbers, and detailed description thereof will be omitted.

The operation of the second embodiment described below is the operation when the mixing mode is specified while the reproduction of the music is being continued in the first reproducing apparatus 1. In the second embodiment shown in FIG. 4, first, the first
Similar to the embodiment, it is determined whether the start of the mixing mode is designated (step S1).

When the mixing mode is started (step S1; YES), it is next determined whether or not the music being reproduced is the beginning of the music (step S10). The determination in step S10 is based on the subcode data detected by the first reproducing device 1 corresponding to the song as the first subcode information recorded on the compact disc 1 ′ together with the song. To be judged.

In step S10, if it is not the beginning of the music, that is, if the middle of one music is being reproduced (step S10; NO), the reproduction of the music is temporarily stopped,
The beginning of the song is searched (step S11). This search is executed by detecting the sub-code data recorded together with the music, similarly to the processing in step S10, and the music head of the music which has been stopped may be searched.
It is also possible to search for the beginning of the next song after the song that has been stopped. After that, when the search for the beginning of the music is completed, the determination of step S10 is executed again.

If it is the beginning of the song in step S10 (step S10; YES), then step S10.
In 2, the reproduction of the music is temporarily stopped (paused), and thereafter, the same operation as in the first embodiment is executed (step S).
3 to step S9). Steps S3 to S9
Since the operation of is similar to that of the first embodiment, detailed description will be omitted.

According to the second embodiment described above, in addition to the effect of the first embodiment, mixing can be started from the beginning of the music even during reproduction of the music. (IV) Third Embodiment Next, a third embodiment corresponding to the invention described in claims 5 to 7 will be described with reference to FIGS. 5 and 6.

Next, the discriminating device 13 determines whether or not the sound effect to be reproduced is a sound effect (for example, a clap sound) preset in the operation section 5 (step S20). This determination is made by detecting sub-code data as sub-code information corresponding to the sound effect recorded on the CD single 2'with the sound effect in the second reproducing device, and based on the detected sub-code data, the operation unit 5 It is determined by comparing with the type of the sound effect input from the above, and if the type of the sound effect is a preset type, the determination signal is output from the determination device 13 to the second CPU 4.

If the kind of the sound effect is not the kind of sound effect set in advance (step S20; NO), the sound effect is of the kind set in advance by waiting as it is.
If the CPU 4 detects it by the discrimination signal (step S20; YES), then the time information of the music piece to be reproduced by the first reproducing apparatus 1 is read from the TOC (Table Of Contents) information of the compact disc 1 '. (Step S21).

Next, in step S22, the read time information is temporarily stored in the memory in the first CPU 3. Then, in step S23, the reproduction of the music is started.

Next, it is judged whether the music piece is the start portion or the end portion of the music piece based on the time information of the music piece stored in the memory (step S24). Then, if it is not the start portion or the end portion of the song (step S24; NO), the reproduction is continued as it is, and if it is the start portion or the end portion of the song (step S24; YES), the sound effect is reproduced. Is started (step S25).

In the processes of steps S24 and S25, when the music is the start portion, the music is temporarily stopped (paused), and after the reproduction of the sound effect is started, the first predetermined time elapses. It is timed by a timer included in the control device 14. Then, the reproduction of the music is restarted by the first CPU 3 after the lapse of the first predetermined time.

If it is determined in step S24 that it is the ending portion of the music, the reproduction of the sound effect is started when the first predetermined time has elapsed from the ending portion. The detection that it is the first predetermined time before the end part is detected by the first CP.
It is detected based on the time information of the music stored in the memory in U3.

The first predetermined time in steps S24 and S25 is preset according to the type of the sound effect judged in step S20. For example, if the sound effect is a clap sound, it is set to 10 seconds. To be done.

Further, the reproduction of the sound effect in step S25 starts when, for example, the sound effect is a clapping sound.
The sound effect may be played back from the beginning, or if it is another sound effect, the processing of steps S4 and S5 (see FIG. 2 or 4) in the first or second embodiment is performed. It is also possible to randomly select a reproduction start position for one sound effect and start reproduction from that position.

When the reproduction of the sound effect is started, the timer included in the timing control device 14 starts the timing,
If the second predetermined time has elapsed (step S26; YE
S), the reproduction of the sound effect is stopped (step S27). If the second predetermined time has not elapsed (step S26; N
O), the reproduction of the sound effect is continued as it is. In addition, in the present embodiment, the second predetermined time is set longer than the first predetermined time.

Here, the change in the reproduction level at the start and end of the reproduction of the sound effect may be changed stepwise, or may be gradually changed as shown in FIG. It is possible.

When the reproduction of the sound effect is stopped (step S
27) Next, it is judged whether or not the reproduction of the music to be reproduced is completed (step S28), and if the reproduction of the music is not completed (step S28; NO), the step for continuing reproduction is performed. Return to S23. If the reproduction of the song is completed (step S28; YES), then the operation unit 5
In step S29, it is determined whether an instruction indicating the end of the mixing mode has been input. If there is no instruction indicating the end (step S29; NO), the mixing operation should be performed on the next music (song). Step S2
Return to 0. When there is an instruction to end the mixing mode (step S29; YES), the process ends.

The relationship between the reproduction of the music (main source) and the sound effect in the operation of the third embodiment described above will be described in detail with reference to FIG. As shown in FIG. 6, when it is detected that the first predetermined time has elapsed from the start of the reproduction of the sound effect in step S25 (see reference numeral A in FIG. 6), the main source (song)
Reproduction is restarted (see symbol B in FIG. 6). Then, after a lapse of the second predetermined time (see reference numeral C in FIG. 6) from the start of reproducing the sound effect (reference numeral A in FIG. 6), the sound effect is stopped.

When it is detected that it is the first predetermined time (see reference numeral E in FIG. 6) from the end of the tune (see reference numeral D in FIG. 6), the reproduction of the sound effect is started again, and then the second reproduction is performed. The sound effect is stopped after the elapse of a predetermined time (see reference numeral F in FIG. 6).

Incidentally, the above steps S21, S22, S
In 24 and S25, the time information is used in the subcode data corresponding to the music, but the address information of the subcode data may be used instead.
