Abstract

The embodiment of the invention provides an audio signal processing method, a reverberation detection method, a conference method, equipment and a storage medium. In the embodiment of the invention, the reverberation parameter of the environment where the terminal equipment is located is introduced, and the reverberation parameter and the signal which is played by the loudspeaker and causes the echo noise are utilized to carry out echo suppression on the signal collected by the microphone, so that the signal after the echo noise is suppressed is obtained, better echo cancellation performance can be achieved, and the user experience is improved. And the quality of signals acquired by the microphone is improved.

Description

technical field [0001] The present application relates to the technical field of audio processing, in particular to an audio signal processing, reverberation detection and conference method, device and storage medium. Background technique [0002] In an audio and video communication system, the local device usually has a speaker and a microphone. The sound played by the speaker can generate echo noise after passing through multiple propagation paths. The echo noise is finally picked up by the local microphone and transmitted to the peer, causing the peer speaker to hear an echo of his own speech. [0003] In the prior art, an adaptive filtering method is usually used to eliminate the echo noise of the audio and video communication system, but the effect of the adaptive filtering method on eliminating the echo noise is not ideal. Therefore, how to eliminate the echo noise of the audio and video communication system is an urgent problem to be solved. Contents of the inventi...
