ABSTRACT:
A sound reproducing apparatus (10) includes a slot (16) to which a memory card (18) is attached. A decoding software for decoding sound data is stored in an audio file recorded on the memory card (18). The decoding software is loaded into a RAM (22b) by a CPU (20) when it is not possible to decode the sound data by the decoding software stored on a ROM (22a). Therefore, a DSP (22) decodes sound data read from the same audio file in accordance with the decoding software loaded from the audio file.
