Abstract

　各レイヤのコア符号化器及びコア復号器を入れ替えた場合でも、拡張符号化器において符号化を可能にすることができるとともに、都度適切なコーデックを使用することにより、精度の高い符号化を行うことができる音声符号化装置。この音声符号化装置（１００）は、下位層のレイヤ情報を上位層で使用して音声信号を階層的に符号化する。また、この音声符号化装置（１００）では、コア符号化器（１０２）は、音声信号を符号化して符号を生成する。コア復号器（１０４）は、コア符号化器（１０２）で生成された符号を復号して復号信号を生成する。加算部（１０６）は、音声信号とコア復号器（１０４）で生成された復号信号との符号化残差を検出する。補助分析部（１０７）は、復号信号を入力して分析処理及び修正処理を行い、下位層のレイヤ情報を生成する。拡張符号化器（１０８）は、音声信号と下位層のレイヤ情報とを用いて符号化残差を符号化する。
