摘要:
A computer-implemented method to detect and reduce feedback in an audio signal is disclosed. The method may include obtaining an audio signal. The method may further include separating the audio signal into a plurality of frequency bands. The method may also include, for each frequency band of the plurality of frequency bands, determining whether the frequency band includes feedback. The method may further include, for each frequency band determined to include feedback, attenuating the frequency band. The method may also include combining each frequency band of the plurality of frequency bands to produce an output audio signal.
