Abstract

　　本来のリスナ位置から離れた位置においても音質的に違和感を生じさせることがないセンターチャンネル定位装置を提供することにある。 　　音声信号処理部（４０）は、処理係数に基づき、センターチャンネル定位用左側音声信号（ＣＬ）及びセンターチャンネル定位用右側音声信号（ＣＲ）の少なくとも一方の位相を変化させ、左側スピーカ（４６）及び右側スピーカ（５２）により、センターチャンネル音声信号（Ｃ）に基づく音声が出力されるようにする。前記処理係数は、前記左側スピーカ（４６）へのセンターチャンネル定位用左側音声信号（ＣＬ）、及び前記右側スピーカ（５２）へのセンターチャンネル定位用右側音声信号（ＣＲ）が同時再生されたときの両耳間レベル差に基づいて、算出されている。
