Original Abstract Submitted
an audio signal encoding method is provided. according to the method, if a current frame is a switching frame, a to-be-encoded downmixed signal and a to-be-encoded residual signal of the subband corresponding to the preset frequency band in the current frame are obtained based on a switch fade-in/fade-out factor of a previous frame, an initial downmixed signal and an initial residual signal of the preset frequency band of the current frame.
