Abstract

The embodiment of the invention provides an active noise reduction method based on audio coding and decoding, an earphone and electronic equipment. The active noise reduction method based on audio encoding and decoding comprises the following steps: decoding audio information in a current environment to obtain a time domain waveform corresponding to the audio information; detecting whether the audio information contains a voice part based on the time domain waveform; if the audio information does not contain the voice part, generating a noise model based on the audio information; and when it is detected that the audio information contains the voice, performing noise reduction coding processing on the mixed audio containing the voice part and the noise based on the noise model to obtain a noise reduction audio. According to the embodiment of the invention, the noise information in the environment is identified and received in real time, and the noise model corresponding to the current environment is established based on the received noise information, so that when the audio is played, the audio is subjected to noise reduction processing based on the noise model, and the noise reduction effect of the earphone and the auditory experience of a user are improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular, to an audio codec-based active noise reduction method, earphones and electronic equipment. Background technique [0002] With the rapid development of electronic technology, earphones, especially true wireless stereo earphones, have been widely recognized by users for their advantages of portability, stable signal, and comfortable wearing. It can be connected with smart terminals such as mobile phones and computers through Bluetooth to realize functions such as data transmission and earphone calls. At present, in the process of using the earphone to make a call, the received noise is relatively large, which interferes with the hearing of the user, thus resulting in a poor call experience for the user. Contents of the invention [0003] Embodiments of the present application provide an audio codec-based active noise reduction method, earphones, and electronic equipmen...
