Title:
AUDIO PROCESSING METHOD AND APPARATUS, ELECTRONIC DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/212905
Kind Code:
A1
Abstract:
An audio processing method and apparatus, an electronic device, and a storage medium, relating to the technical field of sound signal processing. The method comprises: acquiring first audio data of an audio played back (101); calculating by simulation, on the basis of the first audio data, echo data produced by sound waves of the audio played back propagating in a current scene to obtain simulated echo data (102); collecting audio data in the current scene by means of a microphone to obtain mixed audio data (103), the mixed audio data comprising second audio data and real echo data produced by the sound waves of the audio played back propagating in the current scene; and performing echo cancellation processing on the mixed audio data on the basis of simulated echo data to obtain the second audio data (104), such that the effect of echo cancellation is improved.
