Abstract
The disclosure provides a noise reduction method and an electronic device. In an embodiment of the disclosure, when determining that a plurality of first applications occupy a plurality of first audio channels connected with a microphone and a second application occupies a second audio channel connected with a speaker, the electronic device resamples the audio data of the second audio channel according to the sampling rates corresponding to the plurality of first audio channels and then performs the noise reduction processing on the audio data of each of the plurality of first audio channels respectively according to the audio data obtained by resampling.
Claims19
A noise reduction method, comprising:
- determining a plurality of first applications and a second application, wherein the plurality of first applications occupy a plurality of first audio channels connected with a microphone, the second application occupies a second audio channel connected with a speaker, and the plurality of first applications are different from the second application;
- resampling audio data of the second audio channel at each of a plurality of sampling rates of the audio data of the plurality of first audio channels, respectively;
- and
- performing noise reduction processing on the audio data of each of the plurality of first audio channels, respectively, according to the resampled audio data of the second audio channel.
An electronic device, comprising a microphone, a speaker, a memory, and a processor, wherein the memory stores computer instructions and the processor is configured to execute the computer instructions to perform operations of:
- determining a plurality of first applications and a second application, wherein the plurality of first applications occupy a plurality of first audio channels connected with a microphone, the second application occupies a second audio channel connected with a speaker, and the plurality of first applications are different from the second application;
- according to sampling rates of audio data of the plurality of first audio channels, resampling audio data of the second audio channel, wherein sampling rates for the resampling of the audio data of the second audio channel correspond to each of the sampling rates of the audio data of the plurality of first audio channels, respectively;
- and
- performing noise reduction processing on the audio data of each of the plurality of first audio channels according to the resampled audio data of the second audio channel resampled at the sampling rates corresponding to each of the sampling rates of the audio data of the plurality of first audio channels, respectively.
