<P>PROBLEM TO BE SOLVED: To store and reproduce a rhythm sound source with a small capacity. <P>SOLUTION: The rhythm sound source is encoded in the same MP3 system as that of audio data for storing in a ROM 10, and is decoded by an MP3 decode section 70 decoding the audio data for output. Since the rhythm sound source is used repeatedly, one or all of the rhythm sound sources stored in the ROM 10 are decoded by the MP3 decode section 70 in advance for storage in a RAM 12 when a device is started. <P>COPYRIGHT: (C)2008,JPO&INPIT |
