PROBLEM TO BE SOLVED: To keep search processing speed constant without lengthening time for audio data to be actually outputted from a search processing start request in search processing in compressed audio data of variable bit rate. SOLUTION: In search processing, average bit rate of compressed audio data being written by preceding reading is calculated in parallel to reading (reproducing) of compressed audio data written in a temporary storage means, and search processing operation is performed by using the bit rate.
