Howling detection method and apparatus
Abstract:
A howling detection method is provided. A window separation processing is processed on an audio signal to obtain a plurality of analysis windows. A signal energy indicator value of each preset frequency in at least one analysis window is obtained by using a preset perceptual coefficient corresponding to each frequency, to obtain a perceptual energy indicator value of each frequency, the preset perceptual coefficient corresponding to each frequency indicating a sensitivity of a human ear to a sound of each frequency. It is determined whether howling occurs according to the perceptual energy indicator value of each frequency in the at least one analysis window.
