Classification: CPC G  H | IPC G

Claim 0:
1. A multi-channel signal encoding method, comprising:
obtaining a current frame of a multi-channel signal, wherein the current frame includes a first channel signal and a second channel signal;
obtaining a downmixed signal of the current frame based on the first channel signal and the second channel signal;
obtaining an initial reverberation gain parameter of the current frame, wherein the initial reverberation gain parameter corresponds to both of the first channel signal and the second channel signal;
obtaining, based on a first correlation between the first channel signal and the downmixed signal and a second correlation between the second channel signal and the downmixed signal, a value of an identification flag that indicates that the initial reverberation gain parameter of one of the first channel signal or the second channel signal needs to be adjusted;
quantizing, based on the downmixed signal, the initial reverberation gain parameter, and the identification flag, the first channel signal and the second channel signal to obtain a quantized first channel signal and a quantized second channel signal; and
writing the quantized first channel signal and the quantized second channel signal into a bitstream.
