1. A computer-implemented method to detect and reduce feedback in an audio signal, the method comprising:

  • obtaining an audio signal;

    separating the audio signal into a plurality of frequency bands;

    selecting a first frequency band of the plurality of frequency bands;

    obtaining a magnitude threshold and a duration threshold;

    in response to the first frequency band having a magnitude greater than the magnitude threshold for a duration longer than the duration threshold, attenuating the first frequency band; and

    combining the plurality of frequency bands, including the attenuated first frequency band, to produce an output audio signal.
