  Hereinafter, embodiments of a recording apparatus, a recording method, and a computer program for recording control will be described with reference to the drawings. In the following description, as an example of a recording device, performance data generated in accordance with a user's performance (for example, singing or playing a musical instrument) while recording existing music data (existing music data 20) is recorded music. The description will be given using the recording apparatus 1 that newly records data 30. However, as a recording device, a recording device that records other content data while reproducing arbitrary content data other than music data (for example, video data, still image data, text data, and other arbitrary data). It may be adopted.

(1) Configuration of Recording Apparatus 1 The configuration of the recording apparatus 1 of this embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing the configuration of the recording apparatus 1 of this embodiment.

  As shown in FIG. 1, the recording apparatus 1 includes a reproducing unit 11, a data path switching unit 12, a speaker 13, a microphone 14, and a recording buffer 15.

  The reproduction unit 11 is a specific example of “reproduction means”, and reproduces the existing music data 20. Note that the recording device 1 may acquire the existing music data 20 from an external device. In this case, the playback unit 11 includes, for example, a communication unit that communicates with an external device, and a processing circuit that performs playback processing (for example, decoding processing and demodulation processing) on the existing music data 20 acquired by the communication unit. You may have. Alternatively, the recording device 1 may acquire the existing music data 20 loaded on the recording device 1 or recorded on a recording medium. In this case, the playback unit 11 performs playback processing on the existing music data 20 read by the playback head (for example, a magnetic head or an optical pickup) that reads the existing data 20 recorded on the recording medium, for example. A processing circuit or the like may be provided. Of course, the recording apparatus 1 may acquire the existing music data 20 by other methods.

  The existing music data 20 is data (for example, MIDI data, MP3 data, AAC data, etc.) constituting music such as music and performance. The start position detection data 21 indicating that the part is the start part of the existing music data 20 is added to the start part (in other words, the head part) of the existing music data 20. Therefore, when the reproducing unit 11 reproduces the existing music data 20, the start position detection data 21 is reproduced prior to the reproduction of the existing music data 20. The start position detection data 21 may be any data as long as the start portion can be appropriately indicated.

  The data path switching unit 12 is a specific example of “path control means”, and controls the data path among the reproduction unit 11, the speaker 13, the microphone 14, and the recording buffer 15. More specifically, the data path switching unit 12 includes a three-terminal switch 121, a combiner 122, and a switch control unit 123. The first terminal 121 a included in the three-terminal switch 121 is electrically or circuitably connected to the reproduction unit 11 and the first input terminal of the combiner 122. The second terminal 121 b included in the three-terminal switch 121 is electrically or circuitically connected to the microphone 14 and the second input terminal of the synthesizer 122. A third terminal 121c included in the three-terminal switch 121 is electrically or circuitably connected to the recording buffer 15. The three-terminal switch 121 performs switching so that the third terminal 121c is electrically connected to either the first terminal 121a or the second terminal 121b. The output terminal of the synthesizer 122 is connected to the speaker 13. Switching performed by the switch 121 is controlled by the switch control unit 123. Note that the switch control unit 123 controls the operation of the switch 121 according to the type of data being reproduced by the reproduction unit 11.

  When the first terminal 121a and the third terminal 121c are electrically connected, at least one of the existing music data 20 and the start position detection data 21 reproduced by the reproducing unit 11 is output to the recording buffer 15. The In addition, in this case, performance data input from the microphone 14 is output from the speaker 13 via the synthesizer 122. That is, a performance performed by the user of the recording apparatus 1 (that is, a performance input to the recording apparatus 1 via the microphone 14) flows from the speaker 13.

  On the other hand, when the second terminal 121b and the third terminal 121c are electrically connected, at least one of the existing music data 20 and the start position detection data 21 reproduced by the reproducing unit 11 is sent to the synthesizer 122. Is output. In addition, in this case, performance data input from the microphone 14 is output to the synthesizer 122. Therefore, the synthesized music data generated by synthesizing the existing music data 20 and the performance data by the synthesizer 122 is output from the speaker 13. That is, in addition to music corresponding to the existing music data 20, a performance performed by the user of the recording device 1 (that is, a performance input to the recording device 1 via the microphone 14) flows from the speaker 13.

  The speaker 13 is a device that outputs music. As described above, the speaker 13 outputs the existing music data 20 reproduced by the reproducing unit 11 and the performance data input via the microphone 14 as music.

  The microphone 14 is a device that receives an input of a user's performance. As described above, the user performance (that is, performance data) input via the microphone 14 is output to at least one of the speaker 13 and the recording buffer 15 in accordance with the state of the switch 121.

  The recording buffer 15 is an example of “recording means”, and is a storage device for recording user performance (that is, performance data) input via the microphone 14 as recorded music data 30. In addition, in the recording buffer 15, start position detection data 31 indicating that the portion is the start portion of the recorded music data 30 is added to the start portion (in other words, the head portion) of the recorded music data 30. The start position detection data 31 is recorded. The start position detection data 31 may be any data as long as the start portion can be appropriately indicated. Examples of the recording buffer 15 include a semiconductor memory such as a RAM and a flash memory, a hard disk, and the like.

(2) Flow of Operation in Music Distribution System Next, the flow of operation of the recording apparatus 1 of the present embodiment will be described with reference to FIGS. FIG. 2 is a flowchart showing the operation flow of the recording apparatus 1 of the present embodiment. 3 to 6 are block diagrams showing the state of data in the recording apparatus 1 in one process of the operation of the recording apparatus 1 of the present embodiment.

  As shown in FIG. 2, the playback unit 11 starts playback of at least one of the existing music data 20 and the start position detection data 21 (step S101: FIG. 2).

  Here, considering that the start position detection data 21 is added to the start portion of the existing music data 20, it is estimated that the reproduction unit 11 first starts to reproduce the start position detection data 21. At this time, the switch control unit 123 controls the operation of the switch 121 so that the switch 121 performs switching for connecting the reproducing unit 11 and the recording buffer 15. As a result, the switch 121 performs switching so that the reproducing unit 11 and the recording buffer 15 are connected (step S102: FIG. 2). In other words, the switch 121 is recorded with the playback unit 11 while the playback unit 11 is playing back the start position detection data 21 (in other words, while the playback unit 11 has not started playback of the existing music data 20). Switching is performed so that the buffer 15 is connected.

  More specifically, as shown in FIG. 3, the switch 121 performs switching so as to connect the first terminal 121a and the third terminal 121c. In this case, as shown in FIG. 3, the start position detection data 21 reproduced by the reproduction unit 11 is output to the recording buffer 15. In addition, in this case, performance data input from the microphone 14 is output from the speaker 13 via the synthesizer 122.

  Thereafter, as shown in FIG. 4, as playback by the playback unit 11 proceeds, the recording buffer 15 detects the start position as it is or after performing any information processing on the start position detection data 21 played by the playback unit 11. Data 31 is recorded (step S103: FIG. 2).

  Thereafter, the switch control unit 123 determines whether or not the reproduction of the start position detection data 21 is completed by monitoring the data output from the reproduction unit 11 (step S104: FIG. 2). Alternatively, the switch control unit 123 may determine whether or not the reproduction of the existing music data 20 has started by monitoring the data output from the reproduction unit 11.

  As a result of the determination in step S104, when it is determined that the reproduction of the start position detection data 21 has not ended (or the reproduction of the existing music data 20 has not started) (step S104: No: FIG. 2). The recording buffer 15 continues the operation of recording the start position detection data 21 reproduced by the reproduction unit 11 as it is or after performing arbitrary information processing as the start position detection data 31 (step S103: FIG. 2).

  On the other hand, when it is determined that the reproduction of the start position detection data 21 has ended (or the reproduction of the existing music data 20 has started) (step S104: Yes: FIG. 2), the switch control unit 123 switches the switch The operation of the switch 121 is controlled so that 121 performs switching for connecting the microphone 14 and the recording buffer 15. As a result, the switch 121 performs switching so that the microphone 14 and the recording buffer 15 are connected (step S105: FIG. 2).

  More specifically, as shown in FIG. 5, the switch 121 performs switching so as to connect the second terminal 121b and the third terminal 121c. In this case, as shown in FIG. 5, the existing music data 20 reproduced by the reproducing unit 11 is output to the speaker 13 via the synthesizer 122. In addition, in this case, performance data input from the microphone 14 is output to the recording buffer 15 and also output from the speaker 13 via the synthesizer 122.

  Thereafter, as shown in FIG. 6, as playback by the playback unit 11 proceeds, the recording buffer 15 records the performance data input from the microphone 14 as recorded music data 30 as it is or after performing arbitrary information processing. (Step S106: FIG. 2). At this time, the recording buffer 15 records the recorded music data 30 following the start position detection data 31 recorded in step S103. That is, the recording buffer 15 records the recorded music data 30 so that the start position detection data 31 recorded in step S103 is positioned at the start portion of the recorded music data 30.

  As described above, the recording apparatus 1 according to the present embodiment records (i) the start position detection data 31 in the recording buffer 15 while the reproduction unit 11 is reproducing the start position detection data 21, and (ii) While the existing music data 20 is being played back by the playback unit 11, the recorded music data 30 can be recorded in the recording buffer 15. In other words, the recording apparatus 1 of the present embodiment (i) records the start position detection data 31 in the recording buffer 15 while the reproduction unit 11 reproduces the start position detection data 21, and (ii) the reproduction unit. 11, the recording of the recorded music data 30 to the recording buffer 15 can be started. In other words, the recording apparatus 1 of the present embodiment (i) records the start position detection data 31 in the recording buffer 15 and (ii) reproduces before the reproduction of the existing music data 20 is started by the reproduction unit 11. When the reproduction of the existing music data 20 by the unit 11 is started, recording of the recorded music data 30 to the recording buffer 15 can be started.

  As described above, with reference to FIG. 7, the technical effect realized by recording the recorded music data 30 and the start position detection data 31 in accordance with the existing music data 20 and the start position detection data 21 to be played back by the playback unit 11 will be described. To explain. FIG. 7 illustrates a technical effect realized by recording the recorded music data 30 and the start position detection data 31 in accordance with the existing music data 20 and the start position detection data 21 reproduced by the playback unit 11. It is a schematic diagram.

  As shown in FIG. 7A, if the start position detection data 21 is not added to the existing music data 20, the user operates the operation button or the like, for example, to record the recorded music data 30 (that is, performance data). It is necessary to instruct to start recording. However, the position where the recorded music data 30 is recorded in the recording buffer 15 may be different for each recording depending on the accuracy and timing of the operation of the operation buttons. For example, FIG. 7A shows an example in which performance data input through the microphone 14 (that is, recording of the user's performance) is performed three times in accordance with the reproduction of the existing music data 20. Yes. That is, FIG. 7A shows the start portion of the recorded music data 30 recorded in the first recording, the start portion of the recorded music data 30 recorded in the second recording, and the third recording. In this example, the recorded data 30 is shifted from the start of the recording data 30 in time or in position in the recording buffer 15.

  However, in this embodiment, as shown in FIG. 7B, the recorded music data 30 and the start position detection data 31 are recorded in accordance with the reproduction timing of the start position detection data 21 added to the existing music data 20. Therefore, the positions where the recorded music data 30 are recorded in the recording buffer 15 are aligned or easily aligned. Alternatively, even if the position where the recorded music data 30 is recorded in the recording buffer 15 is different every time recording is performed, the recording apparatus 1 can detect the start position detection data added to the recorded music data 30. If 31 is referred, the start part of the recording music data 30 can be specified easily and rapidly. Therefore, even if the position where the recorded music data 30 is recorded in the recording buffer 15 is different every time recording is performed, the recording apparatus 1 can appropriately start from the beginning of the recorded music data 30. Playback can be started. Alternatively, even if the recording music data 30 is recorded in the recording buffer 15 at a position where the recording music data 30 is different every time recording is performed, the recording apparatus 1 accurately determines the start portion of the recording music data 30. Arbitrary data processing (for example, file processing or the like) can be performed on the recorded music data 30 while specifying.

  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 recording apparatus, the recording method, and the recording control accompanying such a change can be used. A computer program is also included in the technical idea of the present invention.
