Abstract
A stereo audio signal processing method is performed by a coding device, and includes: determining a first cross-correlation coefficient for a left channel signal and a right channel signal of a current frame of a stereo audio signal; and in response to the first cross-correlation coefficient being less than a first threshold, obtaining two decorrelation processed channel signals by using a first decorrelation processing method to decorrelate the current frame of the stereo audio signal, calculating a second cross-correlation coefficient for the two decorrelation processed channel signals, and in response to the first cross-correlation coefficient being less than the second cross-correlation coefficient, determining a flag bit to be a first value, obtaining a coded stream based on the two decorrelation processed channel signals, and writing the flag bit into the coded stream, wherein a value of the first threshold is in a range of (−1, 0).
