When the user triggers the fast reverse playback key 422 again, the playback of the audio signal is stopped by the processing unit 110 and the display screen of the sound track editing area 415 is restored.

  The insert recording key 423 is used for overwriting an existing sound track. In the case where a wrinkle is present in the recorded sound track, the user can first select a part having the wrinkle (for example, the selection area 510) from the audio oscillogram 4161. When the setting of the selected area 510 is completed, the user can record again on a part of the sound track in the selected area 510 by enabling the insertion recording key 423. That is, the user can overwrite the selection area 510 with the newly recorded sound track by recording again the part having the habit in the sound track (see FIG. 6A).

  Further, the user can select the next sound track in the editing interface 333 (the key “T” in FIG. 6A displays the next sound track). Also, the processing unit 110 can select the same section from the next sound track in correspondence with the time section of the selection 510. That is, even if the sound tracks are different, the selection area 510 appears in the same time section. For this reason, the user need only switch between different sound tracks, and does not need to set the selection area 510 again (see FIG. 6B).

  According to the present invention, the fast reverse playback key 422 and the insert recording key 423 can be used in combination. First, the user can set the selection area 510 by triggering the fast reverse playback key 422. Next, the user can set the selection area 510 for performing the insertion recording by triggering the insertion recording key 423. When the insertion recording is completed, the processing unit 110 jumps back to the selection area 510 set by the fast reverse reproduction key 422 and reproduces the aforementioned sound track. As a result, when the playback of the selected area 510 set by the fast reverse playback key 422 is completed by the processing unit 110, an indication “cover” is displayed on the touch panel 170. The user can select a “cover” for the soundtrack, or can select “Abandon” to re-record. As a result, the number of times the recording key 417 and the reproduction key 418 are pressed by the user in the selection process of each sound track can be reduced. The power unit 180 can be connected to an external power source or connected to a built-in battery.

  First, the menu interface 331 displayed on the touch panel 170 is referred to. In addition to opening an existing file, the user can create a new file (see FIG. 2A). The following describes soundtrack recording and audio mixing processing using a new file as an example.

  Next, the musical instrument (that is, the sound source end) selected by the user is connected to the electronic device 100. Here, a case where the electronic apparatus 100 is connected to the first musical instrument 210 and the second musical instrument will be described. The input sound track signal corresponding to the first instrument 210 is defined as the first sound signal, and the sound oscillogram 4161 is displayed in the first sound track editing area 415. The input sound track signal corresponding to the second instrument is defined as the second sound signal, and the sound oscillogram 4161 is displayed in the second sound track editing area 415.

  The user can set the recording bit rate and sampling rate of the first musical instrument 210 (or the second musical instrument) using the menu interface 331 before recording. Further, the user can set the number of beats and BPM in the setting interface 330. By touching the beat number adjustment table or the BPM adjustment table, the user can select the corresponding item from the above-mentioned column (see FIG. 2B). The user can determine each related attribute of the output target file 350 by using the bit rate selection field 3311 and the sampling frequency selection item 3312 of the menu interface 331. The bit rate is preferably in the range of 32/64/128/192/320 kbps, for example. The sampling frequency is preferably in the range of 44.1 / 48 / 88.2 / 96 kHz, for example.

  When the electronic apparatus 100 is not recording, the user finds data such as volume, phase, medium tone, bass, and treble input by playing the first musical instrument 210 via the display interface 332. be able to. When the recording key 417 is activated by the user, recording of the first audio signal received by the electronic device 100 is started. The received first audio signal is converted into an audio file of the first sound track via the electronic device 100 and temporarily stored in the memory unit 160. Simultaneously with the input of the first audio signal, the first audio oscillogram 4161 corresponding to the first audio signal is drawn in the sound track editing area 415 via the processing unit 110. Similarly, the second audio oscillogram 4161 of the second audio signal corresponding to the second musical instrument is drawn in the sound track editing area 415 via the processing unit 110.

  After the recording of the sound file of the first sound track and the sound file of the second sound track is completed, the user selects two sound track editing areas 415 on the touch panel 170 and touches the sound mixing key 421. At the same time, the audio mixing interface 340 is displayed on the touch panel 170. The user can adjust the microphone input volume of each sound track, the instrument input volume, the total volume of the sound track, the pan, the mute, and the solo playback key 418 (Solo) in the audio mixing interface 340. The processing unit 110 can mix the sound file of the first sound track and the sound file of the second sound track and output the mixed sound file as the target file 350. When the electronic device 100 is connected to the computer 230, the target file 350 is transmitted to the computer 230 by the electronic device 100.

  In the process from the start to the completion of recording of the sound file of the first sound track (or the sound file of the second sound track), the user can reproduce the sound file of the first sound track. Editing can be performed on a portion of the audio file of the first soundtrack. The user can select the soundtrack to be edited, and can select the corresponding soundtrack editing area 415. The user can then move the cursor to the soundtrack editing area 415 by rotating the shuttle control knob 150. The cursor movement unit is determined according to the number of measures described above. The user can select a starting point and an ending point to be edited from the audio oscillogram 4161 and can define the selected section as a selection area 510. The selection area 510 is distinguished from other parts of the audio oscillogram 4161 by the difference in brightness and color. The user can listen to the sound track of the selected area 510 again using the fast-rewind playback key 422, and can re-record the sound track using the insert recording key 423 and overwrite the selected area 510. is there.

  If the user finds that the recorded soundtrack has a wrinkle, the user can set a wrinkled portion in the audio oscillogram 4161 as the selection area 510. After the setting of the selection area 510 is completed, the user can record again on the sound track in the selection area 510 when the insert recording key 423 is activated. In other words, the user can record again a certain part of the soundtrack, and can overwrite the selection area 510 with the newly recorded soundtrack.

  For the second audio signal, the user can generate an audio file of the second sound track by performing processing corresponding to the above-described method. When recording of another musical instrument is necessary, the electronic apparatus 100 according to the present invention can record the third audio signal or more audio signals as a file. After the sound files of all sound tracks are completed by the user, the user can select a plurality of sound tracks from the sound mixing interface 340 to record by triggering the sound mixing key 421. The processing unit 110 can perform audio mixing on the audio file of the selected sound track and output it as the target file 350.
