Claim 5:
6. The terminal of claim 4, wherein the encoder is further configured to:
encode the stereo parameter according to a first encoding manner when the Nth-frame downmixed signal satisfies a speech frame encoding condition; and
encode the stereo parameter according to a second encoding manner when the Nth-frame downmixed signal does not satisfy the speech frame encoding condition, wherein an encoding rate stipulated in the first encoding manner is greater than or equal to an encoding rate stipulated in the second encoding manner, or wherein a quantization precision stipulated in the first encoding manner is higher than or equal to a quantization precision stipulated in the second encoding manner for any stereo parameter in the Nth-frame stereo parameter set.
