PROBLEM TO BE SOLVED: To allow a plurality of audio apparatuses connected by transmission means with different performance to perform synchronized reproduction.SOLUTION: A buffer allows a first reproduction unit and a second reproduction unit to perform synchronized reproduction by making a second readout position proceed a first readout position by a delay time Td. At the start of inputting an audio signal, the buffer writes silent data corresponding to the delay time Td before the audio signal, sets the first readout position at the beginning of the silent data, sets the second readout position at the beginning of the actual audio signal, and starts reading the audio signal.SELECTED DRAWING: Figure 4 【課題】異なる性能の伝送手段で接続されている複数のオーディオ機器で同期した再生を可能にする。【解決手段】バッファは、第２読出位置を第１読出位置よりも遅延時間Ｔｄ先行させることによって第１再生部および第２再生部で同期再生を行う。オーディオ信号の入力開始時には、オーディオ信号の前に遅延時間Ｔｄ分の無音データを書き込み、第１読出位置を無音データの先頭に設定するとともに、第２読出位置を実際のオーディオ信号の先頭に設定して、オーディオ信号の読み出しを開始する。【選択図】図４
