Claim 11:
12. The method of claim 11, wherein determining the compensation phase signal according to the variable-speed rate of the current audio frame and the candidate phase signal comprises:
acquiring, from the set cache area, a current time domain frame corresponding to the current audio frame and a set number of historical time domain frames before the current time domain frame;
sequentially determining, based on the variable-speed rate of the current audio frame, new candidate phase signals of audio frames corresponding to the set number of historical time domain frames and a new candidate phase signal of the audio frame corresponding to the current time domain frame; and
determining a difference between the new candidate phase signal corresponding to the current audio frame and the candidate phase signal as the compensation phase signal.
