ABSTRACT:
A multiplexed audio data decoder apparatus is provided in which integration of an audio decoder is easy, and has a high flexibility when the number of the formats to be processed is increased or when the specification is changed. In an external ROM60there are accumulated a plurality of decoding program codes corresponding to respective plural methods for compressing and encoding. A controller means50transfers the decoding program code corresponding to the method for compressing and encoding after changing thereof, from the external ROM60to an internal RAM25. A DSP22starts decoding processing by using the decoding program code which is transmitted into the internal RAM25.
