Abstract
This disclosure provides a decoding method, and a decoding apparatus for a stereo signal. The decoding method includes: decoding a bitstream to obtain a first channel signal, a second channel signal, and a first ITD of a current frame of a stereo signal; performing a mixing processing on the first channel signal and the second channel signal, to obtain a third channel reconstructed signal and a fourth channel reconstructed signal; performing interpolation processing based on the first ITD and a second ITD of a previous frame previous to the current frame, to obtain a third ITD; and adjusting a delay of the third channel reconstructed signal and the fourth channel reconstructed signal based on the third ITD.
