Abstract

　本発明に係るオーディオ復号装置（２０）は、ストリーム（２００）をスペクトル係数（２０２）に復号し、ストリーム（２００）に含まれるフレームを復号できない場合にストリーム情報（２０７）を出力するデコード部（２０１）と、スペクトル係数（２０２）を時間信号（２０４）に変換する直交変換部（２０３）と、デコード部（２０１）によりストリーム情報（２０７）が出力された場合、当該ストリーム情報（２０７）が出力されたエラーフレーム区間（ｔ１０）と、隣接するフレーム区間とが重複する区間内であり、かつ当該隣接するフレーム区間の中央部分の区間である基準区間（３２０）の出力波形（２０６）に基づき補正時間信号（２０９）を生成する補正部（２０８）と、補正時間信号（２０９）と時間信号（２０４）とを合成することで、出力波形（２０６）を生成する出力部（２０５）とを備える。
