耦合声道的编、解码处理方法、音频编码装置及解码装置
摘要：
本发明公开了一种耦合声道的编码处理方法，包括：在耦合声道当前帧变换域信号的每个编码单位内，确定其中一个声道作为主声道，并计算另一个声道与所述主声道的关系参数；对所述主声道及所述关系参数进行量化及编码处理。本发明还公开了一种耦合声道的解码处理方法，包括：对反量化后得到的变换域信号，根据主声道及另一个声道与所述主声道的关系参数，恢复出耦合声道。此外，本发明还公开了一种音频编码装置和音频解码装置。本发明所提供的方法及装置，可以有效降低编解码冗余率，提高编码效率。
摘要（英）：

The invention discloses a coupled channel coding processing method, comprising: in each code unit of current frame transform domain of the coupled channel, determining a channel as main channel and calculating the relation parameters of another channel and the main channel; making quantization and coding processing on the main channel and the relation parameters. And the invention discloses a coupled channel decoding processing method, comprising: for the transform domain signal derived from inverse quantization and recovering the coupled channel according to the main channel and the relationparameters; besides, the invention discloses an audio coder and decoder. And the invention can effectively reduce coding and decoding redundancy rate and raise coding efficiency.
