In addition, there has been proposed a music playback device that connects the sound data file of the preceding music piece and the sound data file of the subsequent music piece according to the contents of the command comment to continuously play the preceding music piece and the subsequent music piece.

Japanese Patent No. 3799360

In the above-mentioned DJ play, not only two music pieces are connected and played, but an arrangement operation for applying various effect processing within one music piece may be performed. Arrangement operation means that, for example, during music playback, the user can superimpose previously prepared sounds such as sampling sound and rhythm sound, or filter the music to cut only the low range, only the high range, or only the vocal This is an act of giving various arrangements to music by adding effects such as playing.

However, in the case where a plurality of music pieces are connected and played (continuous play), if the user switches another music piece while performing an arranging operation on a certain piece of music, the user has to interrupt the arranging operation. There are problems such as feeling uncomfortable because it cannot be obtained, and feeling uncomfortable due to switching of music.

Therefore, the present invention provides a music playback device, a music playback method, a music playback program, and a music playback program that can prevent the switching of music as much as possible when a user performs an arrangement operation during connection playback of a plurality of music. It is an object of the present invention to provide a recording medium storing a music reproduction program.

In order to solve the above-described problem, the music playback device according to claim 1 is a playback unit that plays back music data, and a playback that indicates the music data and a playback start position and a playback end position of the music data for each music. The playback means for connecting the storage means for storing the section data and the playback end position of the preceding music to be played back earlier and the playback start position of the subsequent music to be played back later based on the playback section data And a control means for causing the music to be played back, and a music playback device for connecting and playing back a plurality of music, an effect means for adding an effect to the music being played back by the playback means, and an instruction to add the effect to the effect means And an operation input means for inputting the operation, the control means within the predetermined period before the playback end position of the preceding music If there is an input by the force means, said reproduction end position is reproduced in the reproducing device to connect by shifting the position of the rear than the playback end position is characterized by.

The music playback method according to claim 6, wherein for each song stored in advance, the preceding music to be played first based on the music data and the playback section data indicating the playback start position and playback end position of the music data. In a music playback method for playing a plurality of songs by connecting the playback end position of the following music and the playback start position of a subsequent music to be played later, within a predetermined period before the playback end position of the preceding music, When an instruction to add an effect to the music being played is input, the playback end position is shifted to a position behind the playback end position and played back.

The music reproduction program according to claim 7 is a storage in which reproduction means for reproducing music data, and reproduction section data indicating the music data and the reproduction start position and reproduction end position of the music data for each music are stored. And a control means for causing the reproduction means to reproduce so as to connect the reproduction end position of the preceding music to be reproduced first and the reproduction start position of the subsequent music to be reproduced later based on the reproduction section data. In a music reproduction program for connecting a plurality of pieces of music by causing a computer to function, an effect means for adding an effect to the music being reproduced by the reproduction means, and an instruction for adding the effect to the effect means And the control means is configured to cause the computer to function as the operation input means. When there is an input from the operation input means within a predetermined period before the end position, the reproduction means is caused to reproduce so that the reproduction end position is shifted to a position behind the reproduction end position and connected. It is characterized by.

It is a block diagram of the music reproduction apparatus concerning one Example of this invention. It is explanatory drawing of operation | movement when arrangement operation of the music reproduction apparatus shown by FIG. 1 and switching of a music overlap. It is explanatory drawing of operation | movement when arrangement operation of the music reproduction apparatus shown by FIG. 1 and switching of a music overlap. It is a flowchart of an out point change process in case the arrangement operation of the music reproduction apparatus shown by FIG. 1 and the switching of a music overlap. It is a flowchart of a music switching process when arrangement operation of the music reproduction apparatus shown by FIG. 1 and music switching overlap.

Hereinafter, a music reproducing apparatus according to an embodiment of the present invention will be described. The music playback device according to an embodiment of the present invention is configured such that the control unit receives a playback end position when an instruction to add an effect is input by the operation input unit within a predetermined period before the playback end position of the preceding music. Is reproduced by the playback means so as to be connected to a position behind the playback end position, so that when the instruction to add the effect is input (when the arrangement operation is performed), the playback end position is predetermined. When approaching within the period, the end position of the music being played can be shifted, and if the user performs an arranging operation during playback with multiple music connected, music switching will not occur as much as possible Thus, the user can enjoy the arrangement operation as much as possible.

In addition, when the remaining playable remaining time of the preceding music at a position shifted behind the playback end position is equal to or shorter than a predetermined time, the control means connects at the current playback end position without shifting the playback end time. You may make it reproduce | regenerate to a reproduction | regeneration means. By doing this, if it is difficult to shift the playback end position because the arrangement operation is performed near the end position of the preceding music, continuous playback can be performed by connecting at the current playback end position without shifting. By prioritizing the music, the music can be uninterrupted, and the uncomfortable feeling when connecting the music can be reduced.

Also, the control means may cause the playback means to play back so as to connect to a position after a predetermined fixed number of beats or a predetermined bar playback end position. In this way, the playback end position can be shifted in beat units or measure units, and connectivity with subsequent music can be improved rather than simply shifting in time.

The storage means further stores delimiter position data indicating a predetermined block delimiter for each music piece, and the control means sets the playback end position based on the delimiter position data to a delimiter position existing after the playback end position. You may make it reproduce | regenerate to a reproduction | regeneration means so that it may connect and shift. In this way, since the delimiter data is stored in units of A melody, B melody, rust, etc., and the playback end position can be shifted in units of the delimiter data, the musically delimited position can be obtained. Since it can be connected, the connectivity with subsequent music can be improved rather than simply shifting by time.

Further, the predetermined period before the playback end position of the preceding music piece may be set to be longer than the grace period for receiving the input from the next operation input unit. By doing in this way, when the user performs a plurality of arrangement operations as a series of arrangements, it is possible to prevent the music from being switched at the break of one arrangement operation. Can enjoy.

Also, in the music playback method according to the embodiment of the present invention, when an instruction to add an effect is input within a predetermined period before the playback end position of the preceding music, the playback end position is set from the playback end position. Since the playback is performed so that the connection is shifted to the back position, when the instruction to add the effect is input (when the arrangement operation is performed), the playback ends when the playback end position approaches within a predetermined period. The end position of the music can be shifted, and when the user is performing an arrangement operation while connecting and playing multiple songs, the user can enjoy the arrangement operation as much as possible without switching the music as much as possible. be able to.

The music playback program according to the embodiment of the present invention is played back when the control means inputs an instruction to add an effect by the operation input means within a predetermined period before the playback end position of the preceding music. Since the playback means plays back so that the end position is shifted to a position behind the playback end position and connected, when an instruction to add an effect is input (when an arrangement operation is performed), the playback end position Can move the end position of the music being played, and if the user performs an arranging operation during playback with multiple music connected, the music switching will occur as much as possible. In this way, the user can enjoy the arranging operation as much as possible.

Further, the above-described music reproduction program may be stored in a computer-readable recording medium. In this way, the program can be distributed as a single unit in addition to being incorporated in the device, and version upgrades can be easily performed.

An embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the music reproducing device 1 according to an embodiment of the present invention includes a storage unit 2, a decoding unit 3, an effect unit 4, a fader unit 5, an adder 6, and a D / A. A converter 7, an output unit 8, a control unit 9, and an input unit 10 are provided.

The storage unit 2 serving as a storage unit includes, for example, a storage medium such as an optical disk (optical disk drive), a hard disk (hard disk drive), or a memory card (memory card reader) and a reading device thereof, and music data to be reproduced on the storage medium. And playback section data that is data indicating a playback start position (in point) and playback end position (out point) for each music data, music bar data that is data indicating a bar break position for each music, Music block data, which is data indicating a block break specified by music analysis for each music, and music feature data, which is data indicating time-series feature values for each music, are stored.

Music data is encoded and stored in advance by a predetermined method. The music block data block indicates a musical delimiter such as an intro, chorus, A melody, or B melody. The feature amount of the music feature amount data indicates, for example, keys, presence / absence of vocals, chord progression, volume level, etc., and the feature amount, the above-described bar break position and block break position are analyzed and detected by a well-known method. Has been.

The decoding unit 3 as a reproducing means includes a decoding unit A3a and a decoding unit B3b, reads out the music data alternately from the storage unit 2 for each music, decodes (decodes), and outputs to the effect unit 4. For example, when the first music piece is read and decoded by the decoding unit A3a, the next second music piece is read and decoded by the decoding unit B3b, and then the third music piece is read and decoded by the decoding unit A3a. This means the operation.

The effect unit 4 as an effect unit includes an effect unit A4a and an effect unit B4b, and adds the type of effect instructed by the control unit 9 to the music input from the decoding unit 3. The effect unit A4a applies an effect to the output of the decoding unit A3a. The effect unit A4b applies an effect to the output of the decoding unit A3b. The effects added by the effect unit 4 include a process of superimposing preset rhythm sounds and sampling sounds on the music, a filtering process such as cutting only the high range, only the low range, and only the vocal, and the pitch and phase. For example, processing such as changing and adding a predetermined modulation, or matching the tempo of the preceding music and the succeeding music.

The fader unit 5 includes a fader unit A5a and a fader unit B5b, and performs a fade-in process or a fade-out process on the music input from the effect unit 4. For example, when the music is switched from the output of the decoding unit A3a and the effect unit A4a to the output of the decoding unit b3b and the effect unit B4b, the crossfade process, that is, the fader part A5a performs the fadeout process, and the fader part B5b performs the fadein process. Apply.

The adder 6 combines the music output from the fader unit A5a and the music output from the fader unit B5b and outputs the combined music to the D / A converter 7.

The D / A converter 7 converts the music input from the adder 6 into an analog signal and outputs the analog signal to the output unit 8.

The output unit 8 is composed of, for example, an amplifier and an output terminal, and amplifies the analog signal output from the D / A converter 7 and outputs it to the outside.

The control unit 9 as a control means reads the music data to be reproduced from the storage unit 2 by controlling the decoding unit 3 based on the reproduction section data stored in the storage unit 2 and an operation input from the input unit 10 described later. It is made to play (decode), and an effect is added to the effect section 4. In addition, the fader unit 5 is controlled to connect the preceding music piece and the subsequent music piece based on the reproduction section data stored in the storage unit 2.

The input unit 10 serving as an operation input unit includes, for example, a plurality of buttons and dials, and serves as an input unit for operating the music playback device 1. That is, the input unit 10 gives an instruction to add effect processing when the user performs an arrangement operation, or selects the type of effect.

Next, in the music playback device 1 having the above-described configuration, an operation when the arranging operation and music switching (connection) are approaching (overlapping) will be described with reference to FIGS.

FIG. 2 (a) is a diagram in the case where the reproduced music (preceding music) and the connected music (following music) are connected without being arranged. The reproduction music and the connection music are switched to the connection music by performing the MIX effect process for connecting to the connection music in point OP1 of the reproduction music. This MIX effect process is not just crossfading and connecting the playback music and the connected music, but also matching the tempo with the connected music and cutting the male vocal when switching from male vocal to female vocal. In order to improve connectivity, effect processing is also performed at the same time. Note that the effect processing for improving the connectivity with the connected music is selected in consideration of the music feature data near the out point OP1 of the playback music and the music feature data near the in point of the connected music.

FIG. 2B is a diagram in the case where the arrangement operation (arrange effect processing) overlaps with the out point OP1. In the case of FIG. 2B, the arrangement effect process overlaps with the out point OP1, and therefore, the out point OP1 is shifted to the rear out point OP2 by a predetermined predetermined measure. The predetermined measure to be shifted is determined such that the interval between the arrangement effect process and the out point OP2 is longer than the period t1. This period t1 is a wait time for giving a grace to accept the next arrangement operation when the user wants to perform a plurality of arrangement operations continuously. FIG. 2C shows a diagram in the case where the arranging operation is continuously performed.

In FIG. 2C, the second arrangement effect process is performed following the first arrangement effect process (arrangement operation). In this case, since the second arrangement effect process is overlapped only by shifting the predetermined measure from the out point OP1, the process of shifting the predetermined measure is repeated, and the interval between the second arrangement effect process and the out point becomes equal to or longer than the period t1. The MIX effect processing is performed by shifting the position to the out point OP3.

Next, the case where the arrangement effect process approaches the end of the music (overlaps with the end of the music) will be described with reference to FIG. Since FIG. 3A is the same as FIG. 2A, description thereof is omitted. In FIG. 3B, the out point is shifted corresponding to the first arrangement effect process, but the out point is further shifted because the second arrangement effect process is performed. Here, considering the music end time ET and the connection processing time t2, the out point is shifted from the music end time ET to the out point OP4 which is just before the connection processing time t2, and behind this out point OP4. Don't let it go. The music connection process at this time is not a MIX effect but a simple crossfade process. Therefore, even if the third arrangement effect process is performed, the effect process of the MIX effect does not interfere. In other words, continuous playback is continued so that the music is not interrupted, but the user operation has priority over effect processing.

If this arrangement effect process overlaps with the end of the music, the unit for shifting the out point is actually shifted in units of measures as shown in the flowchart described below, so it is not always shifted to a position that matches the out point OP4. Therefore, the position is shifted to a position where it is shifted in bar units and does not exceed the out point OP4.

Next, the above description will be described in detail with reference to the flowcharts of FIGS. These flowcharts are executed by the control unit 9. The flowchart shown in FIG. 4 is a flowchart relating to the out point changing process.

First, in step S11, the flag is initialized to 0 and the process proceeds to step S12. As will be described later, this flag indicates that the out point has not been shifted.

Next, in step S12, it is determined whether or not there is an arrangement operation based on an input from the input unit 10. If there is an arrangement operation (Y), the process proceeds to step S13, and if there is no arrangement operation (N If), wait at this step.

Next, in step S13, it is determined whether or not the current playback position is within a predetermined period before the out point. If it is within the predetermined period (in the case of Y), the process proceeds to step S14, and is not within the predetermined period. In the case of N, the process returns to step S12. In this step, it is determined whether or not the current reproduction position is within the period t1 from the out point. As described with reference to FIG. 2, the out point and the arrange effect process need to be separated from each other by a period t1 or more (more than a grace period for accepting an input from the next input unit 10), and thus the determination is made. This predetermined period is set, for example, in units of measures (such as two measures). Arrangement operations include one in which the effect process ends at the same time as the operation of the input unit 10 and the other in which the effect process ends after a certain period of time has elapsed from the end of the operation of the input unit 10. It depends on. For example, if it is desired to vacate the period t1 by two bars, the effect process may be completed for two predetermined periods when the operation of the input unit 10 ends. What ends is a three-measure period.

Next, in step S14, it is determined whether or not the current playback position is within a predetermined time before the end of the music. If it is within the predetermined time (in the case of Y), the process proceeds to step S16 and is not within the predetermined time. In the case (N), the process proceeds to step S15. In this step, it is determined whether the end point is shifted by checking whether the end of the music is approaching. In the case of the end of the music, as described with reference to FIG. 3, since it can be shifted only to the connection processing time t2 minutes, that is, the out point OP4, it is determined whether or not this is possible. However, since the out point OP4 may be exceeded depending on the relationship between the current position of the out point and the unit for shifting the out point described in step S15, the predetermined time is longer than the out point OP4. This is the time before the unit time to be shifted, that is, the connection processing time t2 + from the end of the music plus the unit time before the shift. For example, if the connection processing time is 2 bars and the shifting unit is 2 bars, the predetermined time of this step is 4 bars. The predetermined time may be set in units of seconds (10 seconds or the like). That is, when the remaining playable time of the preceding music at the position where the out point is shifted backward is equal to or shorter than the predetermined time, the connection is made at the current out point without shifting the out point.

Next, in step S15, the out point is shifted after a predetermined measure and the process returns to step S12. That is, the current out point is shifted by a predetermined predetermined bar (at least the period t1 or more, for example, two bars). Then, the process returns to step S12 to determine whether or not the arranging operation is continued, and this flowchart is repeated. That is, when there is an input by the input unit 10 within a predetermined period before the out point of the preceding music, the out point is shifted to a position behind the out point.

On the other hand, in step S16, the flag is set to 1 and the process returns to step S12. This flag indicates that the end of music is approaching and the out point has not been shifted, and is used in the flowchart shown in FIG.

The operation of the flowchart of FIG. 4 will be described using specific numerical examples. For example, if the predetermined period of step S13, the predetermined bar of step S15 is 2 bars, and the predetermined time of step S14 is 10 seconds, if it is 2 bars before the current out point, it must be 10 seconds before the end of the song , Shift the out point back by two bars. In other words, it is shifted backward by four bars from the determination point in step S13. If the arrangement operation is performed at the time when the two-bar playback has progressed, another two-bar deviation occurs, and this is until the step S14 is determined to be Y, that is, 10 seconds before the music end time ET. Can be repeated.

Next, the flowchart regarding the music switching process shown in FIG. 5 will be described. This flowchart is executed by the control unit 10.

First, in step S21, it is determined whether or not it is an out point. If it is an out point (Y), the process proceeds to step S22. If it is not an out point (N), the process waits in this step.

Next, in step S22, it is determined whether or not the flag is 1. If it is 1 (Y), the process proceeds to step S23. If it is not 1 (N), the process proceeds to step S24. That is, it is determined whether or not the current playback position is approaching the end of the music and the out point has not been shifted.

Next, in step S23, fade processing is performed to connect the music, and the process proceeds to step S25. That is, since the flag is 1, the end of the music is so close that the out point cannot be shifted, so the MIX effect is not performed, and a simple fade process (crossfade process) is performed.

On the other hand, in step S24, MIX effect processing is performed and the process proceeds to step S25. In this step, since the flag is not 1, the end of music is not approaching, so normal MIX effect processing is performed.

Next, in step S25, the flag is set to 0 and the process ends. That is, the flag is initialized because the music is switched.

According to the present embodiment, when an arrangement operation is performed within a predetermined period t1 before the out point of the preceding music, the out point is reproduced so as to be shifted to a position behind the predetermined bar, so that the arrangement operation is performed. If the out point approaches when the song is performed, the connection position of the song being played can be shifted, and if the user performs an arranging operation while playing multiple songs connected, It is possible to enjoy the arranging operation as much as the user wishes without making switching as much as possible.

Also, if the remaining playable time of the preceding music at the position where the out point is shifted by a predetermined bar is less than the predetermined time, the music is played so as to be connected at the current out point. If it is difficult to shift the out point when an arrangement operation is being performed in the vicinity, priority is given to continuous playback by connecting at the current playback end position without shifting, and the music is connected without interruption. The feeling of discomfort at the time can be reduced.

In addition, because the playback is performed so that the out point for the specified measure is shifted and connected to the back position, the out point can be shifted in units of measures, and the connectivity with the subsequent music is improved rather than simply shifting by the time. be able to.

Since the arrangement effect processing and the out point are separated by a predetermined period t1 minutes, a grace period for accepting an operation from the next input means can be provided, and a plurality of arrangement effect operations can be arranged in a series. When the user is performing, it is possible to prevent the music from being switched at the break of one arrangement operation, and to enjoy the arrangement operation as much as the user desires.

In the embodiment described above, the out point is shifted in units of measures, but may be shifted in units of beats. Further, the position may be shifted based on music block data (separation position data) indicating a predetermined block separation such as A melody, B melody, and chorus. For example, when music is composed in the order of A melody, B melody, and chorus, and the out point is set in the A melody, if the out point is shifted to overlap with the arrangement operation, the end of the A melody Try to shift the out point. That is, based on the music block data, the out point is shifted and connected to a delimiter position existing after the out point.

In the embodiment described above, a grace period for accepting the next arrangement operation is provided between the arrangement effect process and the MIX effect process. That is, there may be a MIX effect process immediately after the arrange effect process. However, as described above, it is not possible to deal with a plurality of arrangement effect operations, so it is preferable to provide a grace period as in the embodiment. In short, if the arrangement effect process overlaps with the out point, the out point may be shifted backward to a position where it does not overlap.

Further, by configuring the storage unit 2, decoding unit 3, effect unit 4, fader unit 5, addition unit 6, control unit 9, input unit 10, and the like as a program that operates on a computer, the present invention can be used as a music reproduction program. Can be configured.
