Abstract

See full text

A method for processing an audio signal is provided. In the method, audio signals sent by at least two sound sources are acquired by at least two microphones to obtain multiple frames of original noisy signals of each microphone on a time domain. For each frame, frequency-domain estimation signals of each sound source are acquired according to the original noisy signals of the at least two microphones. For each sound source, the frequency-domain estimation signals are divided into multiple frequency-domain estimation components on a frequency domain. For each sound source, feature decomposition is performed on a related matrix of each frequency-domain estimation component to obtain a target feature vector. A separation matrix of each frequency point is obtained based on target feature vectors and the frequency-domain estimation signals. The audio signals of sounds are obtained based on the separation matrixes and the original noisy signals.
