The audio encoded data that is received is decoded by selecting an optimal decoding unit according to the encoding format identifier added to the data or according to set information notified from audio communication device 201 of the communication partner. The audio data decoded is temporality stored in audio data buffer 216 and reproduced. The amount of audio data stored in the audio data buffer is controlled so that audio is reproduced without pause.
