Claim 0:
1. A terminal configured to obtain a multi-channel audio signal, comprising:
an encoder comprising a predetermined first algorithm and configured to:
mix Nth-frame audio signals of two of a plurality of channels of the multi-channel audio signal, based on the first algorithm to obtain an Nth-frame downmixed signal, wherein N is a positive integer greater than zero;
detect whether the Nth-frame downmixed signal comprises a speech signal; and
when no speech signal is detected, encode the Nth-frame downmixed signal into a bitstream when the Nth-frame downmixed signal satisfies a preset audio frame encoding condition; and

a transmitter coupled to the encoder and configured to transmit the bitstream.
