Embodiment Construction

[0022] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0023] With the development of electronic devices, the electronic devices are usually used by users to play audio, collect sounds, and the like. When an electronic device is used, there may be situations where the electronic device performs audio playback and sound collection at the same time, for example, the electronic device performs a voice call in a speaker mode. When an electronic device performs audio playback and sound collection at the same time, the sound played by the speaker is inevitably recorded by the microphone, and the sound played by the device is collected by the device's own microphone, causing an echo to appear in the sound collected by the microphon...

Abstract

The invention discloses an audio processing method and device, electronic equipment and a storage medium. The audio processing method is applied to the electronic equipment, and the electronic equipment comprises a loudspeaker, a first microphone and a second microphone, wherein the first microphone is arranged outside a cavity of a box body corresponding to the loudspeaker, and the second microphone is arranged in the cavity of the box body. The audio processing method comprises the following steps: controlling the loudspeaker to play an audio signal to be played; acquiring a first audio signal acquired by the first microphone when the loudspeaker plays the audio signal to be played; acquiring a second audio signal acquired by the second microphone when the loudspeaker plays the audio signal to be played, and taking the second audio signal as a reference audio signal for echo cancellation; and performing echo cancellation on the first audio signal according to the obtained reference audio signal to obtain a third audio signal after echo cancellation. According to the method, the echoes in the sounds collected by the microphone can be well eliminated.

Description

technical field [0001] The present application relates to the technical field of audio processing, and more specifically, to an audio processing method, device, electronic equipment, and storage medium. Background technique [0002] With the rapid advancement of technology and living standards, electronic devices (such as smart phones, tablet computers, smart watches, etc.) are used more and more widely and have more and more functions, and have become one of the must-haves in people's daily life. The electronic device is usually provided with a speaker for playing sound, and also provided with a microphone for collecting sound. When an electronic device is used, there may be situations where a microphone and a speaker need to work together. For example, when a remote call is made, the speaker and the microphone need to work simultaneously. [0003] When the microphone and the speaker work together, there will be an echo in the sound collected by the microphone, and the ech...
