| 摘要 |
An audio decoding device includes a decoding section for decoding an audio bit stream to generate PCM data and outputting input channel configuration information, a control section for receiving input channel configuration information, normalization method instruction information, externally specified normalization coefficient information and output control information and controlling internal processing, and an audio processing section for performing audio processing to PCM data. The normalization processing section performs normalization processing using the externally specified normalization coefficient information when the normalization method instruction information indicates external specification. The audio processing section performs normalization processing using the input channel configuration information and the output control information when the normalization method instruction information indicates internal calculation.
