AUDIO SIGNAL SWITCHING METHOD AND DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for switching an audio signal.SOLUTION: A method for switching an audio signal includes: a step (101) for weighting a first high frequency band signal of the audio signal of a current frame and a second high frequency band signal of the audio signal of previous M frames to obtain a processed first high frequency band signal when the audio signal is switched; and a step (102) for synthesizing the processed first high frequency band signal and a first low frequency band signal of the audio signal of the current frame into a wide frequency band signal.
