A METHOD AND DEVICE FOR SWITCHING PROCESSING OF AUDIO FREQUENCY SIGNALS

摘要

A method and a device for switching processing of audio frequency signals are provided, wherein the method includes: acquiring the feature information of the audio frequency signals in the end state of the first stage before the conversion moment in the switching stage of the frequency bands, slowly switching the audio frequency signals from the first frequency band to the second frequency band during the first stage; determining the feature information of the initial state of the second stage after the conversion moment in the switching stage of the frequency bands based on the feature information in the end state of the first stage, and slowly switching the frequency band of the audio frequency signals with the feature information of the initial state during the second stage.
