Claim 7:
8. The audio signal encoder according to claim 7, wherein to perform the channel combination scheme modification decision for the current frame based on the initial channel combination scheme for the current frame to determine the channel combination scheme for the current frame, the instructions, which when executed by the one or more processor, cause the audio signal encoder to
if a channel combination ratio factor modification flag of the previous frame indicates that a channel combination ratio factor needs to be modified, determine that the channel combination scheme for the current frame is the anticorrelated signal channel combination scheme; or
if the channel combination ratio factor modification flag of the previous frame indicates that the channel combination ratio factor does not need to be modified, determine whether the current frame meets a switching condition, and determine the channel combination scheme for the current frame based on a result of determining whether the current frame meets the switching condition.
