发明名称 Audio player and audio fast-forward playback method capable of high-speed fast-forward playback and allowing recognition of music pieces
摘要 Audio data to be played back is associated with meta data indicating the timing of beat that serves as a basis for a rhythm of a music piece. In a fast-forward playback mode, the associated meta data is read. A portion of the audio data containing the timing of beat is determined as a playback portion A and the remaining portion in a beat-to-beat interval C is determined as a non-playback portion B. Only the playback portion A is sequentially played back and output. The relative duration of a playback portion A and a non-playback portion B is determined according to a playback speed required in fast-forward playback.
