Abstract
Provided is an audio reproduction device capable of immediately starting to reproduce audio data, particularly compressed audio data, from an arbitrary point in a forward 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 data is temporarily stored in a RAM. Then, the stored compressed data is decoded by a decoder, thereby extracting a segment of PCM data. The segment of PCM data is supplied 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 data stored in the PCM data buffer formed in the RAM is reproduced by a reproduction processing circuit, thereby reducing a rapid change in reproduction speed.
