摘要：Provided is an audio reproduction device capable of immediately starting toreproduce audio data, particularly compressed audio data, from an arbitrary point in aforward or a backward direction at an arbitrary speed. In the case where data, to be

reproduced, which is stored in a storage device is compressed data, the compressed datais temporarily stored in a RAM. Then, the stored compressed data is decoded by adecoder, thereby extracting a segment of PCM data. The segment of PCM data issupplied to a PCM data buffer formed in a RAM via a reproduction controlling

microcomputer. Based on an operation of a rotational operation element, the PCM datastored in the PCM data buffer formed in the RAM is reproduced by a reproductionprocessing circuit, thereby reducing a rapid change in reproduction speed.
