  In this main recording device, when recording a user's performance, an appropriate level adjustment (in other words, gain adjustment) is performed so that the volume level of the recorded performance becomes an optimum recording level. Specifically, for example, during performance recording, level adjustment is performed so that the volume level is as high as possible within a range where clipping noise does not occur. However, when a plurality of performances recorded so as to achieve the optimum recording level are reproduced while being mixed, the following technical problems arise. This is because even if a performance is recorded so as to achieve an optimum recording level, the intention of the user who is actually performing is not necessarily reflected in the recording level. More specifically, even if the user performs a performance by changing the intensity of the sound, the performance is recorded while the level is automatically adjusted so that the optimum recording level is obtained. For this reason, the recorded performance may not reflect the intention of the user (that is, the intention of the user's expression for the performance). Therefore, when a plurality of recorded performances are reproduced while being mixed, the reproduction may be performed in a manner that does not conform to the user's intention when the performance is recorded.

  Hereinafter, embodiments of a recording apparatus, a recording method, and a computer program for recording control, and a reproducing apparatus, a reproducing method, and a computer program for reproducing control will be described in order.

(Embodiment of recording apparatus)
The recording apparatus according to the present embodiment records as performance data an input means for inputting a performance of a user, an output means for outputting the performance input to the input means, and the performance input to the input means. Recording means; and creation means for creating level value information indicating a difference between a monitor level, which is a volume level of the performance output from the output means when the performance is recorded, and a predetermined volume level.

  According to the recording apparatus of this embodiment, a user's performance (for example, performance using a user's song or a musical instrument etc.) is input into input means, such as a microphone, for example. The performance input to the input means is recorded as performance data by the recording means. Furthermore, the performance input to the input means is output from output means such as a speaker. Therefore, the user can perform the performance (and record the performance) while listening to the performance performed by the user himself / herself.

  Particularly in the present embodiment, the creating means creates level value information indicating a difference between the monitor level and a predetermined volume level. The “monitor level” is the volume level of the user's performance that is output from the output means when the user's performance is recorded. Therefore, the “monitor level” is substantially synonymous with the volume level of the user's performance that the user himself / herself is listening to when recording the user's performance (that is, the volume level recognized by the user). Further, the level value information may be information that directly indicates the difference between the monitor level and a predetermined volume level. Alternatively, the level value information may be information that indirectly indicates a difference between the monitor level and a predetermined volume level (in other words, information that can be converted into a difference by performing some calculation or the like).

  Thus, the recording apparatus of the present embodiment can create level value information in addition to recording performance data. Here, for example, when the performance is recorded, if the volume level (that is, the monitor level) of the performance output from the output means is relatively large, the user intends to perform with a relatively loud sound. It is also estimated that On the other hand, when the performance is recorded, if the volume level (that is, the monitor level) of the performance output from the output means is relatively low, the user has an intention to perform with a relatively low sound. It is also estimated that Therefore, the recording apparatus of the present embodiment can appropriately reflect the user's intention when recording the performance on the performance data indicating the performance by creating the level value information.

  In addition, a playback device that plays back performance data refers to the level value information, so that the original intention of the user with respect to the performance expressed by the performance data (for example, the intention regarding the performance mode, for example, the strength of the performance) Can be recognized. Therefore, the playback device can play back the performance expressed by the performance data in a manner reflecting the user's intention by adjusting the volume level of the performance expressed by the performance data based on the level value information. .

  In the present embodiment, an example is described in which the level value information is information indicating a difference between the monitor level and a predetermined volume level. However, the level value information may be any information that directly or indirectly specifies the monitor level.

  According to this aspect, the recording apparatus according to the present embodiment creates level value information indicating the difference between the recording level and the monitor level, so that the user's intention when recording the performance is set as performance data indicating the performance. Can be appropriately reflected. In particular, since the recording apparatus only needs to use two volume levels (that is, a monitor level and a recording level) relating to the user's performance, it does not use a volume level or an arbitrary reference level for performances other than the user's performance. Get better. Therefore, the recording apparatus can record the level value information even when the user is performing without accompaniment, for example.

  In the aspect of the recording apparatus in which the level value information indicates the difference between the recording level and the monitor level as described above, the first adjustment means for adjusting the monitor level at the previous stage of the output means, and the recording level at the previous stage of the recording means. Second adjusting means for adjusting the recording level, and the creating means monitors the adjustment amount by the first adjusting means and the adjustment amount by the second adjusting means, so that the recording level and the monitor level are adjusted. The difference may be created as the level value information.

  If comprised in this way, the recording device can produce suitably the level value information which shows the difference of a recording level and a monitor level.

  In another aspect of the recording apparatus of the present embodiment, the output means outputs, in addition to the performance input from the input means, other performances input from other input means as accompaniment, and the level value information Indicates the difference between the accompaniment level, which is the volume level of the other performance being output as the accompaniment, and the monitor level.

  According to this aspect, the recording apparatus according to the present embodiment creates level value information indicating the difference between the accompaniment level and the monitor level, so that the user's intention when recording the performance is set as performance data indicating the performance. Can be appropriately reflected.

  In the aspect of the recording apparatus in which the level value information indicates the difference between the accompaniment level and the monitor level as described above, the first adjustment means for adjusting the monitor level in the previous stage of the output means, and the accompaniment level in the previous stage of the output means And a third adjusting unit that adjusts the accompaniment level and the monitor level by monitoring the adjustment amount by the first adjusting unit and the adjustment amount by the third adjusting unit. The difference may be created as the level value information.

  If comprised in this way, the recording device can produce suitably the level value information which shows the difference of an accompaniment level and a monitor level.

  In another aspect of the recording apparatus of the present embodiment, the level value information indicates a difference between a reference level that is a reference volume level and the monitor level.

  According to this aspect, the recording apparatus according to the present embodiment creates level value information indicating the difference between the accompaniment level and the monitor level, so that the user's intention when recording the performance is set as performance data indicating the performance. Can be appropriately reflected. In particular, the recording apparatus can substantially represent the monitor level by using a reference level that is a common value regardless of recording or output of the user's performance. For this reason, the recording apparatus can appropriately create level value information, for example, even when the user is performing without accompaniment or whatever performance the user performs. .

  In another aspect of the recording apparatus of the present embodiment, the level value information includes a reference difference value that is a difference between the predetermined volume level and a reference monitor level, and the predetermined volume level and the recording time of the performance. The difference from the current difference value, which is the difference from the monitor level.

  Hereinafter, embodiments of a recording apparatus, a recording method, a computer program for recording control, and a reproducing apparatus, a reproducing method, and a computer program for controlling reproduction will be described with reference to the drawings. In the following, as an example of a system to which the recording device and the playback device are applied, (i) the user performance is recorded (recorded) by the client terminal 20 as part data 1111 and the recorded part data 1111 is recorded as music. Uploaded to the server 10, (ii) the part data 1111 is distributed from the music server 10 to the client terminal 20, and (iii) the distributed part data 1111 and the recorded part data 1111 are reproduced on the client terminal 20. The description will be given using the music reproduction system 1. In this case, the client terminal 20 is an example of a recording device and a playback device.

(1) Configuration of Music Distribution System First, the configuration of the music distribution system 1 of the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing the configuration of the music distribution system 1 of this embodiment.

  As shown in FIG. 1, the music distribution system 1 includes a music server 10, a client terminal 20, and a network 30.

  The music server 10 stores a plurality of part data 1111 constituting music. The part data 1111 stored in the music server 10 is, for example, part data 1111 uploaded (in other words, transmitted) from the client terminal 20 to the music server 10. However, the music server 10 may store the part data 1111 acquired in other modes. Each part data 1111 corresponds to performance data corresponding to one of a plurality of parts (that is, one of a plurality of instrument parts or performance parts) constituting the music. However, when the performance data corresponds to stereo sound (that is, the L channel sound and the R channel sound are separately provided), the performance data corresponding to the L channel sound and the R channel sound are provided. Each piece of performance data corresponding to may be handled as part data 1111. Part data 1111 will be described later in detail (see FIG. 3 and the like).

  In addition, the music server 10 distributes (in other words, transmits) desired part data 1111 to the client terminal 20 in response to a request from the client terminal 20.

  The client terminal 20 uploads the part data 1111 to the music server 10. The part data 1111 uploaded by the client terminal 20 is, for example, part data 1111 created by a user of the client terminal 20 actually playing a musical instrument. However, the client terminal 20 may upload the part data 1111 created or acquired in another manner.

  In addition, the client terminal 20 requests the music server 10 to distribute desired part data 1111 among the plurality of part data 1111 stored in the music server 10. As a result, the client terminal 20 downloads (in other words, obtains or receives) the desired part data 1111 distributed from the music server 10. Thereafter, the client terminal 20 may reproduce the acquired part data 1111.

  The network 30 is a network line that connects the music server 10 and the client terminal 20. The network 30 may be a wired network line, a wireless network line, or a combination of a wired network line and a wireless network line.

  FIG. 1 shows an example in which the music distribution system 1 includes one music server 10. However, the music distribution system 1 may include a plurality of music servers 10. In this case, the client terminal 20 uploads the part data 1111 to at least one of the plurality of music servers 10 and downloads the part data 1111 from at least one of the plurality of music servers 10. Good.

  FIG. 1 shows an example in which the music distribution system 1 includes one client terminal 20. However, the music distribution system 1 may include a plurality of client terminals 20. In this case, a certain client terminal 20 may download the part data 1111 uploaded by another client terminal 20.

  FIG. 1 shows an example in which the music server 10 stores and distributes part data 1111. However, the music server 10 may store and distribute arbitrary performance data or music data in addition to or instead of the part data 1111.

(2) Configuration of Music Server Next, the configuration of the music server 10 of this embodiment will be described with reference to FIG. FIG. 2 is a block diagram showing the configuration of the music server 10 of this embodiment.

  As shown in FIG. 2, the music server 10 includes a database 110, a control unit 120, a display information generation unit 130, and a data communication unit 140.

  The database 110 includes a part data storage unit 111 for storing a plurality of part data 1111 uploaded from the client terminal 20.

  Here, a plurality of part data 1111 stored in the part data storage unit 111 included in the database 110 will be described with reference to FIGS. Here, FIGS. 3 to 5 are schematic views showing aspects of the plurality of part data 1111 stored in the part data storage unit 111 included in the database 110, respectively.

  As shown in FIG. 3, the part data storage unit 111 preferably stores a plurality of part data 1111 in a state of being classified according to a predetermined rule. Here, as an example of the rules, there are the song name of the music composed of the part data 1111, the tempo of the music composed of the part data 1111, and the like. Accordingly, it is preferable that one or a plurality of part data 1111 constituting music pieces having the same music title and having the same tempo constitute a data group classified by the same rule. For example, in the example shown in FIG. 3, one or a plurality of part data 1111 constituting a song having a song name “XXX” and a tempo “102 bpm (Beat Per Minute)” is a rule. In a state in which a data group classified into the category A is configured, it is stored in the part data storage unit 111. Similarly, in the example shown in FIG. 3, one or a plurality of part data 1111 constituting a song having a song name “xxx” and a tempo “88 bpm” is classified into a rule B. The data group is stored in the part data storage unit 111 in a state where the data group is configured.

  In order to store a plurality of part data 1111 in a state classified according to such rules, each time the new part data 1111 is stored, the part data storage unit 111 stores the song name and tempo of the new part data 1111. The new part data 1111 may be classified according to the rule by analyzing the same (that is, the characteristic characterizing the rule). However, the new part data 1111 is stored on the client terminal 20 by recording the user's own performance with other part data 1111 downloaded from the music server 10 as an accompaniment. Is relatively often the timing at which is generated. In this case, the song name and tempo of the new part data 1111 coincide with the song names and tempos of the other part data 1111 as the accompaniment. Therefore, in such a case, the part data storage unit 111 does not analyze the song name, tempo, etc. of the new part data 1111, and other part data 1111 that accompanies the new part data 1111. It may be determined that it is classified into the same rule as the rule to be classified.

  In addition, the part data storage unit 111 preferably stores a plurality of part data 1111 constituting a data group classified by the same rule in a state of being classified for each part. For example, in the example shown in FIG. 3, a plurality of part data 1111 constituting a data group classified into the category of rule A includes one or more part data 1111 corresponding to a lead guitar and one or more corresponding to chorus. Are classified into one part data 1111 corresponding to a bass, one part data 1111 corresponding to a drum, and one part data 1111 corresponding to a vocal. Stored. Similarly, in the example shown in FIG. 3, a plurality of part data 1111 constituting a data group classified into the category of rule B includes one or more part data 1111 corresponding to the lead guitar and one or more corresponding to the base. Stored in a state of being classified into a plurality of part data 1111, one or more part data 1111 corresponding to the drum, and one or more part data 1111 corresponding to the vocal.

  In order to store a plurality of part data 1111 in such a state classified for each part, the part data storage unit 111 stores a part corresponding to the new part data 1111 each time new part data 1111 is stored. It is preferable to classify the new part data 1111 for each part by analysis.

  Alternatively, as shown in FIG. 4, the part data storage unit 111 may store a plurality of part data 1111 constituting a data group classified by the same rule in a state of being grouped in units of bands. Good. Here, the “band” refers to a set of one or a plurality of parts for constituting one musical piece. That is, a plurality of part data 1111 collected in units of bands are reproduced while being mixed on the client terminal 20, so that a state where one piece of music is played by a virtual band is substantially realized. The In the example shown in FIG. 3, in the data group classified into the classification of rule A, one part data 1111 corresponding to the lead guitar, one part data 1111 corresponding to the drum, and one part data corresponding to the vocal A data group from a combination of part data 1111 and one part data 1111 corresponding to the base is stored in a state of being grouped in units of band # 1. Similarly, in the example shown in FIG. 3, in the data group classified into the rule A, one part data 1111 corresponding to the lead guitar, one part data 1111 corresponding to the drum, and the base A data group from a combination with one part data 1111 is stored in a state of being grouped in a unit of band # 2. The band # 2 data group corresponds to a so-called “minus one” data group that does not include the part data 1111 corresponding to the vocal as compared to the band # 1 data group.

  At this time, each part data 1111 stored in a state of being grouped in units of bands is stored together with mixing information indicating a setting mode (for example, volume, pan, etc.) when mixing with other part data 1111. It may be. Therefore, when mixing a plurality of part data 1111 collected in units of bands, the client terminal 20 preferably mixes with reference to the mixing information recorded together with the part data 1111. Thereby, the client terminal 20 can perform appropriate mixing of the plurality of part data 1111.

  Such storage of each part data or each band or each band of the part data 1111 by the part data storage unit 111 is logically performed by predetermined management information stored in the part data storage unit 111 together with the part data 1111, for example. May be realized. For example, the part data storage unit 111 stores a plurality of part data 1111 itself as they are without being directly distinguished, and manages the classification of each part or band for each rule of the stored part data 1111. Management information may be stored separately. In this case, the music server 10 can recognize that a plurality of part data 1111 is stored on the part data storage unit 111 in the manner shown in FIGS. 3 and 4 by referring to the management information. However, the part data storage unit 111 may physically realize storage for each part, for each part, or for each band, by dividing a physical partition.

  Here, in this embodiment, as shown in FIG. 5, each part data 1111 directly or indirectly indicates the monitor level when each part data 1111 is created (that is, recorded) on the client terminal 20. It is recorded in a state combined with the level value data 1112 shown. Here, the “monitor level” indicates the volume level of the performance output as sound from the client terminal 20 when the user of the client terminal 20 creates the part data 1111 by actually playing the instrument. . The “monitor level” and the level value data 1112 will be described later in detail with reference to the drawing (FIG. 8) showing the configuration of the client terminal 20, and thus detailed description thereof is omitted here.

  2 shows an example in which the part data storage unit 111 is provided in the database 110 provided in one music server 10. However, the part data storage unit 111 may be distributed and provided across the plurality of databases 110 included in the plurality of music servers 10. That is, the part data storage unit 111 may be distributed in a plurality of music servers 10 so as to adopt a so-called cloud form.

  In FIG. 2 again, the control unit 120 is a central control device (for example, CPU: Central Processing Unit) that controls the operation of the entire music server 10. The control unit 120 includes a data communication control unit 121 as a physical, logical, or functional processing block realized therein.

  The data communication control unit 121 controls the data communication unit 140 to distribute the part data 1111 requested from the client terminal 20 and the level value data 1112 corresponding to the part data 1111. In addition, the data communication control unit 121 controls the data communication unit 140 to receive the part data 1111 uploaded from the client terminal 20 and the level value data 1112 corresponding to the part data 1111. The data communication control unit 122 stores the received part data 1111 and level value data 1112 in the part data storage unit 111.

  The display information generation unit 130 generates display information (for example, GUI (Graphic User Interface) information) necessary for the client terminal 20 to display a predetermined screen. The display information generation unit 130 transmits the generated display information to the client terminal 20 via the data communication unit 140. As a result, the client terminal 20 displays a screen generated based on the display information transmitted from the music server 10.

  The data communication unit 140 performs communication with the client terminal 20 via the network 30 under the control of the data communication control unit 121. Accordingly, the part data 1111 and the level value data 1112 uploaded from the client terminal 20 are acquired by the data communication unit 140. The acquired part data 1111 and level value data 1112 are stored in the part data storage unit 111 by the data communication control unit 121. Further, the part data 1111 requested from the client terminal 20 is read from the part data storage unit 111 by the data communication control unit 121. In addition, level value data 1112 corresponding to the read part data 1111 is also read from the part data storage unit 111 by the data communication control unit 121. The read part data 1111 and level value data 1112 are distributed from the data communication unit 140 to the client terminal 20 under the control of the data communication control unit 121.

(3-1) Overall Configuration of Client Terminal Next, the configuration of the client terminal 20 of this embodiment will be described with reference to FIG. FIG. 6 is a block diagram showing the configuration of the client terminal 20 of this embodiment.

  As shown in FIG. 6, the client terminal 20 includes a storage device 210, a control unit 220, a display unit 230, a data communication unit 240, a voice input unit 250, a voice output unit 260, and an operation unit 270. Prepare.

  The storage device 210 temporarily or permanently stores data used in the process of data processing in the client terminal 20. Examples of the storage device 210 include a semiconductor memory such as a ROM, a RAM, and a flash memory, a hard disk, and the like.

  The control unit 220 is a central control device (for example, CPU: Central Processing Unit) that controls the operation of the entire client terminal 20. The control unit 220 includes a display control 221, an audio control unit 222, an operation control unit 223, and a data communication control unit 224 as physical, logical, or functional processing blocks realized therein. I have.

  Based on the display information transmitted from the display information generation unit 130 of the music server 10, the display control unit 221 uses a predetermined screen (for example, a screen for accepting an instruction for operating the client terminal 20 from the user) The operation of the display unit 230 is controlled so as to display a screen showing the state of the client terminal 20 to the user. In the present embodiment, the display control unit 221 issues an instruction to record the user's performance via the audio input unit 250 as part data 1111 and an instruction to upload the recorded part data 1111 to the music server 10 from the user. You may display the screen for accepting. Further, the display control unit 221 may display a screen for accepting an instruction to download a desired part data 1111 out of a plurality of part data 1111 stored in the music server 10 from the user. For this reason, it is preferable that the display information transmitted from the display information generation unit 130 of the music server 10 includes various information necessary for displaying such a screen. However, the display control unit 221 may generate various kinds of information necessary for displaying the screen from scratch without being based on the display information transmitted from the display information generation unit 130 of the music server 10.

  The voice control unit 222 controls recording of a user performance (for example, voice of vocal or chorus, voice by performance of each instrument, etc.) via the voice input unit 250. The recorded performance may be stored in the storage device 210 temporarily or permanently. Furthermore, the voice control unit 222 creates level value data 1112 corresponding to the recorded user performance. In addition, the audio control unit 222 controls the performance of the user via the audio input unit 250 and the output of the part data 1111 downloaded from the music server 10 as audio from the audio output unit 260.

  The operation control unit 223 receives a user operation using the operation unit 270 and notifies each unit in the client terminal 20 of the content of the received user operation so that an operation according to the received operation is performed. For example, when the operation control unit 223 receives a user operation for instructing recording as part data 1111 of the user's performance via the voice input unit 250, the operation control unit 223 notifies the voice control unit 222 that the operation has been received. Notice. As a result, the voice control unit 222 controls the operation of the voice input unit 250 so as to record the user performance as part data 1111.

  For example, when the data communication control unit 224 receives a notification from the operation control unit 223 that the user's operation instructing the upload of the part data 1111 is accepted, the data communication control unit 224 is recorded under the control of the voice control unit 222. The data communication unit 240 is controlled to upload the part data 1111 and the level value data 1112 corresponding to the part data 1111 to the music server 10. As a result, the part data 1111 recorded under the control of the audio control unit 222 and the level value data 1112 corresponding to the part data 1111 are uploaded from the client terminal 20 to the music server 10 via the data communication unit 240. Is done.

  In addition, the data communication control unit 224, for example, notifies the operation control unit that a user instruction to download a desired part data 1111 out of a plurality of part data 1111 stored in the music server 10 has been received. If received from 223, the data communication unit 240 is controlled to transmit a message requesting the music server 10 to download the desired part data 1111. As a result of such a request, desired part data 1111 (and level value data 1112 corresponding to the desired part data 1111) is downloaded from the music server 10 to the client terminal 20 via the data communication unit 240. Is done.

  Here, with reference to FIG. 7, the download and reproduction of the desired part data 1111 realized by the control of the data communication control unit 224 and the level value data 1112 corresponding to the desired part data 1111 will be described. FIG. 7 is a schematic diagram schematically showing how the desired part data 1111 realized by the control of the control unit 220 and the level value data 1112 corresponding to the desired part data 1111 are downloaded and reproduced. .

  As shown in FIG. 7, the client terminal 20 uploads part data 1111 created by recording (recording) a performance together with level value data 1112 corresponding to the part data 1111. As a result, the uploaded part data 1111 and level value data 1112 are stored in the part data storage unit 111 while being distinguished, for example, in units of bands.

  Furthermore, as shown in FIG. 7, the client terminal 20 may request download of a plurality of part data 1111 collected in units of bands. That is, under the control of the data communication control unit 224, the client terminal 20 includes four part data 1111 (specifically, one piece corresponding to the lead guitar) included in the data group collected in the unit of band # 1. Part data 1111, one part data 1111 corresponding to the drum, one part data 1111 corresponding to the vocal, and one part data 1111 corresponding to the base may be requested to be downloaded. As a result, under the control of the data communication control unit 224, the client terminal 20 has one part data 1111 corresponding to the lead guitar, one part data corresponding to the chorus, and one part data 1111 corresponding to the base. Then, one part data 1111 corresponding to the drum and one part data 1111 corresponding to the vocal are individually downloaded for each part. At this time, the client terminal 20 downloads the level value data 1112 corresponding to each part data 1111 in addition to each part data 1111.

  However, the client terminal 20 may request download of arbitrary part data 1111 regardless of the unit of band.

  As a result, the client terminal 20 adjusts the volume level of each downloaded part data 1111 based on the corresponding level value data 1112 under the control of the audio control unit 222. Thereafter, each part data 1111 whose volume level has been adjusted is mixed under the control of the audio control unit 222 and then output (ie, reproduced) as audio from the audio output unit 260.

  In FIG. 2 again, the data communication unit 240 performs communication with the music server 10 via the network 30 under the control of the data communication control unit 224. Accordingly, the part data 1111 and the level value data 1112 uploaded from the client terminal 20 are transmitted to the music server 10 via the data communication unit 240. Further, the part data 1111 and the level value data 1112 distributed from the music server 10 in response to a request from the client terminal 20 are acquired by the data communication unit 240. The acquired part data 1111 and level value data 1112 may be temporarily or permanently stored in the storage device 210 by the data communication control unit 224, or may be output from the audio output unit 260.

(3-2) Configuration of Voice Control Unit that Records Level Value Data Next, the configuration of the voice control unit 222 that creates the level value data 1112 will be described with reference to FIG. FIG. 8 is a block diagram showing the configuration of the voice control unit 222 provided in the client terminal 20.

  As shown in FIG. 8, the audio control unit 222 includes a recording level adjustment amplifier 2221, a monitor level adjustment amplifier 2222, a performance recording unit 2223, and k (where k is an integer of 1 or more) accompaniment levels. An adjustment amplifier 2224_k, an adder 2225, a level value data creation unit 2226, and an adder 2227 are provided.

  The recording level adjustment amplifier 2221 is a specific example of “second adjustment means”, and its input terminal is connected to the audio input unit 250, and its output terminal is the performance recording unit 2223 and the monitor level adjustment amplifier. The amplifier is connected to the input terminal 2222. The recording level adjusting amplifier 2221 adjusts the volume level of the user's performance so that the volume level of the user's performance input via the audio input unit 250 becomes the optimum recording level. In the following description, the volume level of the user's performance output from the recording level adjustment amplifier 2221 will be referred to as “recording level D” and the description will proceed.

  The monitor level adjusting amplifier 2222 is a specific example of “first adjusting means”, and its input terminal is connected to the output terminal of the recording level adjusting amplifier 2221 and its output terminal is connected to the adder 2227. Amplifier. The monitor level adjusting amplifier 2221 adjusts the volume level of the user's performance so that the user's performance input via the audio input unit 250 is output from the audio output unit 260 at a volume level appropriate for the user. In the following description, the volume level of the user's performance output from the monitor level adjusting amplifier 2222 will be referred to as “monitor level B”.

  The performance recording unit 2223 is a specific example of “recording means”, and the performance of the user whose volume level is adjusted by the recording level adjusting amplifier 2221 (that is, the performance of the user whose volume level is the recording level D). ). That is, the performance recording unit 2223 records the user's performance whose volume level is adjusted by the recording level adjustment amplifier 2221 as part data 1111. In other words, the performance recording unit 2223 creates part data 1111 corresponding to the user's performance whose volume level is adjusted by the recording level adjusting amplifier 2221. The performance recording unit 2223 may temporarily store the created part data 1111 in the storage device 210 or upload it to the music server 10 via the data communication unit 240.

  Each of the k accompaniment level adjustment amplifiers 2224 — k is a specific example of “third adjustment means” or “adjustment means”, and its input terminal is a specific example of “acquisition means”. Is an amplifier whose output terminal is connected to the adder 2225. Each accompaniment level adjustment amplifier 2224 — k adjusts the volume level of the part data 1111 downloaded via the data communication unit 240 based on the level value data 1112 corresponding to the part data 1111.

  The adder 2225 is a specific example of “reproducing means”, and synthesizes at least one part data 1111 whose volume level is adjusted by at least one of the k accompaniment level adjusting amplifiers 2224 — k (that is, the adder 2225). , Mix). The part data 1111 mixed by the adder 2225 is output to the adder 2227. In the following description, the volume level of the part data 1111 output from the adder 2225 is referred to as “accompaniment level A”.

The level value data creating unit 2226 is a specific example of “creating means”, and creates level value data 1112 that can specify the monitor level B directly or indirectly. For example, the level value data creation unit 2226 may create level value data 1112 indicating the difference C (= BD) between the monitor level B and the recording level D. In this case, the monitor level B is specified based on the level value data 1112 and the recording level D. Alternatively, the level value data creation unit 2226 may create level value data 1112 indicating the difference C (= BA) between the monitor level B and the accompaniment level A. In this case, the monitor level B is specified based on the level value data 1112 and the accompaniment level A. Alternatively, the level value data creation unit 2226 may create level value data 1112 indicating the difference C (= B−T) between the monitor level B and a predetermined reference level T set in advance. In this case, the monitor level B is specified based on the level value data 1112 and the reference level T. Alternatively, the level value data creation unit 2226 may calculate a difference C ₀ (= B ₀ −D (or A or T)) corresponding to a predetermined monitor level B ₀ and a difference C (== Level value data 1112 indicating a difference ΔC (= C−C ₀ ) from BD (or A or T)) may be created.

  The level value data creation unit 2226 preferably monitors the monitor level B, the recording level D, and the accompaniment level A in order to create such level value data 1112. The monitor level B, the recording level D, and the accompaniment level A are the volume level adjustment amount in the monitor level adjustment amplifier 2222, the volume level adjustment amount in the recording level adjustment amplifier 2221, and the volume level in the accompaniment level adjustment amplifier 2224_k. It depends on the adjustment amount. Accordingly, the level value data creation unit 2226, in addition to or instead of directly monitoring the monitor level B, the recording level D, and the accompaniment level A, the monitor level adjustment amplifier 2222, the recording level adjustment amplifier 2221, and the accompaniment level adjustment. The amount of volume level adjustment in the amplifier 2224_k may be monitored.

  The adder 2227 is a specific example of “reproducing means”, and synthesizes (that is, mixes) the mixed part data 1111 and the performance of the user whose volume level is adjusted by the monitor level adjusting amplifier 2222. . The part data 1111 mixed by the adder 2227 and the performance of the user are output from the audio output unit 260 as audio.

(4) Flow of Operation of Client Terminal Subsequently, with reference to FIGS. 9 to 11, the operation of the client terminal 20 of the present embodiment (particularly, the operation at the time of recording the user's performance by the client terminal 20 and the client terminal 20). The flow of the operation when reproducing the part data 1111 according to the above will be described. FIG. 9 is a flowchart showing the flow of operations when recording the performance of the user by the client terminal 20 of the present embodiment. FIG. 10 is a flowchart showing the flow of operations when reproducing the part data 1111 by the client terminal 20 of the present embodiment. FIG. 11 is an explanatory diagram illustrating an aspect of adjusting the volume level of the part data 1111 based on the level value data 1112 performed by the client terminal 20 of the present embodiment.

  As shown in FIG. 9, at the time of recording a user performance, the data communication control unit 224 downloads part data 1111 output as an accompaniment at the time of recording the user performance (step S100). ). For example, when the user's performance is a guitar performance, the data communication control unit 224 may download the part data 1111 of parts other than the guitar. Note that the operation in step S100 may be substantially the same as the operations in step S201 (step for requesting download) and step S202 (step for actually downloading) shown in FIG.

  Thereafter, the audio control unit 222 starts reproduction of the part data 1111 downloaded in step S100 (that is, reproduction of accompaniment) (step S101). Specifically, the accompaniment level adjustment amplifier 2224 — k included in the audio control unit 222 adjusts the volume level of the downloaded part data 1111. Thereafter, the adder 2225 mixes the part data 1111 whose volume level has been adjusted. As a result, the volume data adjusted and mixed part data 1111 is output from the audio output unit 260 as an accompaniment.

  The user's performance is started simultaneously with or in parallel with the accompaniment reproduction in step S101 (step S102). Along with the start of the user's performance, the performance recording unit 2223 included in the voice control unit 222 records the user's performance (that is, the user's performance whose volume level is adjusted by the recording level adjusting amplifier 2221) (step S103). . As a result, part data 1111 is created. At this time, the performance recording unit 2223 may temporarily store the created part data 1111 in the storage device 210.

  In parallel with the recording of the user's performance, the level value data creation unit 2226 included in the voice control unit 222 detects the monitor level B (step S104).

In addition, in parallel with the recording of the performance of the user, the level value data creation unit 2226 included in the voice control unit 222 detects at least one of the accompaniment level A, the recording level D, and the reference level T (step S105). For example, the level value data creation unit 2226 detects the recording level D when creating level value data 1112 indicating the difference C (= BD) between the monitor level B and the recording level D. In this case, the level value data creation unit 2226 may not detect the accompaniment level A and the reference level T. Alternatively, for example, the level value data creation unit 2226 detects the accompaniment level A when creating level value data 1112 indicating the difference C (= B−A) between the monitor level B and the accompaniment level D. In this case, the level value data creation unit 2226 may not detect the recording level D and the reference level T. Alternatively, for example, the level value data creation unit 2226 detects the reference level T when it is desired to create level value data 1112 indicating the difference C (= B−T) between the monitor level B and the reference level T. In this case, the level value data creation unit 2226 may not detect the recording level D and the accompaniment level A. Alternatively, for example, the level value data creation unit 2226 may calculate the difference C ₀ (= B ₀ −D (or A or T)) corresponding to the predetermined monitor level B ₀ and the difference C corresponding to the current monitor level B. When the level value data 1112 indicating the difference ΔC (= C−C ₀ ) with respect to (= B−D (or A or T)) is to be created, the accompaniment level A, the recording level D, and the reference level T What is necessary to create the difference ΔC is detected.

  Thereafter, the level value data creation unit 2226 creates level value data 1112 based on at least one of the monitor level B detected in step S104 and the accompaniment level A, recording level D, and reference level T detected in step S105. (Step S106). At this time, the level value data creation unit 2226 may temporarily store the created level value data 1112 in the storage device 210.

  Thereafter, the data communication control unit 224 uploads the user performance recorded in step S103 (that is, the part data 1111) and the level value data 1112 created in step S106 to the music server 10 (step S107). ).

  Subsequently, as shown in FIG. 10, when creating the part data 1111, the client terminal 20 selects a desired one of the plurality of part data 1111 stored in the music server 10 under the control of the data communication control unit 224. The music server 10 is requested to download the part data 1111 (step S201). Specifically, for example, the user of the client terminal 20 looks at a screen (for example, a screen for selecting desired part data 1111) displayed on the display unit 230 under the control of the display control unit 221. Desired part data 1111 is designated by an operation using the operation unit 270. The operation using the operation unit 270 by the user is detected by the operation control unit 223. As a result, the operation control unit 223 can specify the desired part data 1111 that the user requests to download. As a result, the data communication control unit 224 that receives the notification from the operation control unit 223 uses the data communication unit 240 to specify a predetermined message or control signal that can specify the desired part data 1111 that the user requests to download. Is transmitted to the music server 10.

  As a result, the data communication control unit 121 of the music server 10 receives, via the data communication unit 140, a predetermined message or control signal that can specify the desired part data 1111 that the user requests to download. As a result, the data communication control unit 121 specifies desired part data 1111 and reads the specified part data 1111 from the part data storage unit 111. Further, the data communication control unit 121 specifies the level value data 1112 corresponding to the desired part data 1111 and reads the specified level value data 1112 from the mixing data storage unit 112. Thereafter, the data communication control unit 122 distributes the desired part data 1111 requested by the user to download and the level value data 1112 corresponding to the desired part data 1111.

  As a result, the data communication unit 240 included in the client terminal 20 downloads the desired part data 1111 and the level value data 1112 corresponding to the desired part data 1111 (step S202).

  Thereafter, the downloaded part data 1111 is input to any one accompaniment level adjusting amplifier 2224 — k. The accompaniment level adjustment amplifier 2224_k adjusts the volume level of the input part data 1111 based on the level value data 1112 corresponding to the part data 1111 (step S203). More specifically, for example, the accompaniment level adjustment amplifier 2224 — k may amplify the volume level of the input part data 1111 by the difference C indicated by the level value data 1112. At this time, if the difference C indicates the monitor level B-recording level D (or accompaniment level A or reference level T), the accompaniment level adjusting amplifier 2224_k determines the volume level of the input part data 1111. It is preferable to amplify the difference C indicated by the level value data 1112. FIG. 11 shows a mode in which the volume level is amplified by the difference C when the difference C has a negative value (that is, the volume level is attenuated by the absolute value | C | of the difference C). ing. Alternatively, for example, the accompaniment level adjustment amplifier 2224 — k may attenuate the volume level of the input part data 1111 by the difference C indicated by the level value data 1112. At this time, when the difference C indicates the recording level D (or accompaniment level A or reference level T) -monitor level B, the accompaniment level adjusting amplifier 2224_k determines the volume level of the input part data 1111. It is preferable to attenuate by the difference C indicated by the level value data 1112. The operation in step S203 is preferably performed as many times as the number of downloaded part data 1111.

  Thereafter, the adder 2225 synthesizes (that is, mixes) the part data 1111 whose volume level has been adjusted. As a result, the mixed part data 1111 is output as audio from the audio output unit 260 (step S204).

  As described above, the client terminal 20 of the present embodiment can create the level value data 1112 in addition to recording the performance of the user (that is, creating the part data 1111). Here, for example, when the user's performance is recorded, if the volume level of the user's performance output from the audio output unit 260 (that is, the monitor level B) is relatively large, the user is relatively It is also presumed that he intends to play with loud sound. On the other hand, if the volume level (that is, monitor level B) of the user's performance output from the audio output unit 260 when the user's performance is being recorded is relatively low, the user will hear a relatively low sound. It is also presumed that he has an intention to play with. Therefore, the client terminal 20 of the present embodiment can appropriately reflect the user's intention when recording the performance on the part data 1111 indicating the performance by creating the level value data 1112.

  As a result, when reproducing the recorded performance (that is, the part data 1111 created by recording the user's performance), the client terminal 20 refers to the level value data 1112, and uses the part data 1111. It is possible to recognize the original intention of the user for the performance to be expressed (for example, the intention regarding the performance mode, for example, the degree of the strength of the performance). Therefore, the client terminal 20 reproduces the part data 1111 appropriately mixed in a manner reflecting the user's intention by adjusting the volume level of the part data 1111 to be reproduced based on the level value data 1112. be able to.

  If the volume level of the part data 1111 is not adjusted based on the level value data 1112, the downloaded part data 1111 is mixed with the part data 1111 whose volume level is the recording level D as it is. become. That is, mixing is performed with the part data 1111 having the volume level shown on the leftmost side in FIG. Therefore, this mixing does not reflect the intention of the user who can be recognized by specifying the monitor level B. However, in this embodiment, as described above, the volume level of the part data 1111 is temporarily adjusted based on the level value data 1112. Therefore, the part data 1111 appropriately mixed in a manner reflecting the user's intention is reproduced. can do.

  In addition, in this embodiment, the difference C between the monitor level B and the recording level D can be used as the level value data 1112. Therefore, the client terminal 20 includes the difference C (= BD) indicated by the level value data 1112 and the original recording level D (that is, the adjustment amount of the recording level adjusting amplifier 2221 that can be recognized by the client terminal 20). Based on the above, it is possible to appropriately specify the monitor level B when the part data 1111 is created. Further, in this case, the client terminal 20 can appropriately create the level value data 1112 even when there is no accompaniment or the like.

  In addition, in this embodiment, the difference C between the monitor level B and the accompaniment level A can be used as the level value data 1112. Therefore, the client terminal 20 includes the difference C (= B−A) indicated by the level value data 1112 and the original accompaniment level D (that is, the adjustment amount of the accompaniment level adjustment amplifier 2224 — k that can be recognized by the client terminal 20). Based on the above, it is possible to appropriately specify the monitor level B when the part data 1111 is created. Furthermore, in this case, the client terminal 20 can create level value data 1112 reflecting the balance between the accompaniment output when the user's performance is recorded and the actual user's performance.

  In addition, in this embodiment, the difference C between the monitor level B and the reference level T can be used as the level value data 1112. For this reason, the client terminal 20 appropriately sets the monitor level B at the time of creating the part data 1111 based on the difference C (= B−T) indicated by the level value data 1112 and the reference level T common to the client terminal 20. Can be identified. Further, in this case, the client terminal 20 can appropriately create the level value data 1112 even when there is no accompaniment or the like or whatever performance the user performs. In addition, in this case, a specific meaning can be added to the difference C by appropriately setting the reference level T.

In addition, in the present embodiment, as the level value data 1112, the above-described difference ΔC (= C ₀ (= B ₀ −D (or A or T) −C (= BD (or A or T))). Therefore, when considering that the difference ΔC is smaller than the difference C described above, the volume level of the part data 1111 based on the level value data 1112 performed by the accompaniment level adjusting amplifier 2224 — k is used. The adjustment amount is relatively small.

  Further, the present invention can be appropriately changed without departing from the gist or concept of the invention that can be read from the claims and the entire specification, and the distribution device, the distribution method, and the distribution control for such a change can be changed. A computer program, a playback apparatus, a playback method, and a computer program for playback control are also included in the technical idea of the present invention.
