Abstract

　本発明の音声信号再生装置及び音声信号再生システムは、ＳＬｃｈの再生音は、Ｌｃｈ及びＳＢＬｃｈスピーカー位置に配置された２つのスピーカー５ａ及び５ｄより適度に調整された合成音で再生し、またＳＲｃｈスピーカーの再生音は、Ｒｃｈ及びＳＢＲｃｈスピーカー位置に配置された２つのスピーカ５ｂ及び５ｅより適度に調整された合成音で再生することを特徴としている。このような構成により、５．１ｃｈ音場システム対応のスピーカー接続にも拘わらず、コンテンツに含まれるＬＰＣＭ７．１ｃｈの音声情報の内、５．１ｃｈ分の音声をそのまま出力するとともに、２ｃｈ分の音声を擬似的に再生することで、高音質な５．１ｃｈバーチャル再生を実現することができる。
