Abstract
A method for processing a stereo audio signal, performed by an encoding device, includes: determining an initial first threshold Thresh01 and an initial second threshold Thresh02 of a current frame of the stereo audio signal, where Thresh01∈(−1,0), and Thresh02∈(0,1); determining an offset value Delta; determining a first threshold Thresh1 and a second threshold Thresh2 corresponding to the current frame of the stereo audio signal according to a de-correlation manner for a previous frame of the stereo audio signal, the offset value Delta, the initial first threshold Thresh01 of the current frame, and the initial second threshold Thresh02 of the current frame; and performing de-correlation on the current frame according to the first threshold Thresh1 and the second threshold Thresh2 corresponding to the current frame.
