Abstract
Disclosed in the present application are an audio enhancement method and apparatus, and a computer storage medium. The method comprises: generating a group of audio collection signals by means of a microphone array; performing delay-and-sum processing on the group of audio collection signals, so as to generate a delay-and-sum signal; performing blocking matrix processing on the group of audio collection signals, so as to generate a blocking matrix signal; using an adaptive filtering matrix to filter the blocking matrix signal, and removing the filtered blocking matrix signal from the delay-and-sum signal, so as to obtain an enhanced audio output signal. The adaptive filtering matrix is based on at least one attenuation function, and each of the at least one attenuation function is updated at an interval of a corresponding predetermined update interval T.
