Abstract

The invention relates to an audio processing method and device, electronic equipment and a storage medium. The audio processing method comprises the following steps: detecting whether delay jitter exists in audio data acquisition and playing processes or not; when the delay jitter is detected, resetting the state of an AEC system; and using the AEC system with the reset state for executing acoustic echo cancellation processing, wherein the AEC system with the reset state is higher than the AEC system with the reset state in terms of the acoustic echo cancellation degree.

Description

technical field [0001] The present disclosure relates to the field of signal processing, and in particular to an audio processing method, device, electronic equipment and storage medium. Background technique [0002] The AEC system is often used in call scenarios (for example, conference applications, live streaming, and game voice) to eliminate the voice of the opposite end of the call and retain the voice of the near-end. For mobile phones, PCs, macOS, etc. on different platforms, delay jitter will generally occur during AEC work. This kind of jitter is usually caused by uneven system collection and playback callback data or uneven system thread scheduling. However, the AEC system cannot perceive this delay jitter, and can only rely on the convergence of the internal acoustic model (eg, adaptive filter), and in this case, the phenomenon of echo leakage will occur. Contents of the invention [0003] The present disclosure provides an audio processing method, device elec...
