ＡＴＳＣ数字音频压缩（ＡＣ－３）标准（七）７．４声道耦合７．４．１概述如能做到，在编码中通过将变换系数在包含于耦合声道中各声道之间取平均，来实现声道耦合。各被耦合声道有一套唯一的耦合坐标，用于保存原始声道的高频包络。在ｃｐｌｂｅｇｆ定义的耦合频率以上...
ATSC Digital Audio Compression (AC-3) standard 7.4 Channel Coupling 7.4.1 General If this is done, the transform coefficients are included in the code of each channel included in the coupling channel Average, to achieve the channel coupling. Each coupled channel has a unique set of coupling coordinates for preserving the high-frequency envelope of the original channel. Above the coupling frequency defined by cplbegf ...
