Beschreibung
Zusammenfassung:	An audio decoding apparatus for decoding and reproducing a plurality of compressed audio streams simultaneously without sound interruption, even when the number of samples per frame is different. The audio decoding apparatus includes: a first and second audio decoder which decode two inputted compressed audio streams, and output audio data; a first and second intermediate buffer which temporarily hold the outputted audio data; a first and second audio output unit which convert the audio data into audio signals and output such audio signals; an output control unit which reads the audio data from the first and second intermediate buffer, and transmits the audio data to the first and second audio output unit. The output control unit repeats the reading and transmission of either the same number of samples of audio data or the number of samples of audio data for the same amount of transmission time.
