Abstract

The invention provides an audio processing method and device, electronic equipment and a storage medium, and belongs to the technical field of sound signal processing. The method comprises the following steps: acquiring first audio data of played audio; based on the first audio data, simulating and calculating echo data generated by propagation of sound waves of a played audio in a current scene,and obtaining simulated echo data; collecting audio data in the current scene through a microphone to obtain mixed audio data, the mixed audio data comprising second audio data and real echo data generated by propagation of sound waves of played audio in the current scene; and performing echo cancellation processing on the mixed audio data based on the analog echo data to obtain the second audio data. By adopting the technical scheme provided by the invention, the echo cancellation effect can be improved.

Description

technical field [0001] The present application relates to the technical field of audio signal processing, and in particular to an audio processing method, device, electronic equipment, and storage medium. Background technique [0002] In a voice interaction scenario, the electronic device can realize the cooperative work of the microphone and the speaker, that is, the electronic device can collect the user's voice through the microphone while playing audio through the speaker. Since the sound wave has the characteristic of reflection and propagation, the audio data collected by the microphone not only includes the user's audio data, but also includes the echo data of the audio played by the speaker. [0003] In the related art, in order to eliminate the echo, the electronic device may collect the audio played by the speaker through a sampling loop to obtain the first audio data. Then, the electronic device may perform echo cancellation processing on the mixed audio data col...
