Digital recorder for recording grouped and interleaved digital data of multiple tracks

摘要

Audio data of multiple tracks is grouped and stored as if for one track on a hard disk. More specifically, audio data of multiple tracks is interleaved in association with track grouping and is stored in a buffer memory before being recorded on the hard disk. In play mode, the interleaved audio data is output via the buffer memory from the hard disk. At this time, the audio data is deinterleaved to be restored to the original multitrack audio data.
