Single-chip microcomputer can control the playback time, select a specific period of time many of the players, as well as single-channel recording, easy to FLASH memory by changing the external playback time change. We make a simple model, only playback. Required only when the recording and playback-side oscillation of the external resistor ROSC will be able to change different recording and playback of sound speed, the shorter the time of admission, the better sound quality, longer recording sound worse using direct analog storage technology, Thus the high-fidelity, better sound quality
