Abstract
An audio decoding device includes a playback speed change device for changing, with respect to a decoded audio signal obtained by a decoding device, the playback speed thereof; an output buffer for temporarily storing a digital audio signal outputted from the playback speed change device; a read out device for reading out the digital audio signals stored in the output buffer at predetermined time intervals; a playback speed control device for controlling the playback speed change device on the basis of the number of packets stored in the jitter buffer; and decoding timing control means for controlling the timing of decoding by the decoding device on the basis of the amount of data stored in the output buffer.
