Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a multiplexed audio data decoding device capable of easily integrating audio decoders and having high flexibility even when the number of formats to be processed is increased or when specifications are changed. SOLUTION: Plural decoding processing codes corresponding to plural compression encoding formats are stored in an external ROM 11. When a user changes a compression encoding format by changing the specification of data series, a control means 10 transfers a decoding processing code corresponding to the changed compression encoding format from the external ROM 11 to an internal RAM 5. A DSP 3 starts decoding processing by using the decoding processing code transferred to the RAM 5.
