摘要：The present invention provides a multichannel audio signal processing method,an apparatus, and a system, and relates to the field of audio encoding and decoding

technologies, to resolve a problem in the prior art that an audio signal cannot bediscontinuously transmitted in a multichannel audio communications system. An encoderincludes a signal detection unit and a signal encoding unit. The signal encoding unit isconfigured to: when the signal detection unit detects that an N-frame downmixed signalincludes a speech signal, encode the N-frame downmixed signal; or when the signaldetection unit detects that the N-frame downmixed signal does not include a speechsignal: encode the N-frame downmixed signal if the signal detection unit determines thatthe N-frame downmixed signal satisfies a preset audio frame encoding condition, or skipencoding the N-frame downmixed signal if the signal detection unit determines that theN-frame downmixed signal does not satisfy a preset audio frame encoding condition. Inthis technical solution, because encoding on a downmixed signal is discontinuous, theproblem in the prior art that the audio signal cannot be discontinuously transmitted isresolved.
