Abstract

The invention relates to an audio signal processing method and device, terminal equipment and a storage medium. The method comprises the following steps: acquiring original noise signals acquired by at least two audio signal channels; distinguishing a noise signal frame and a voice signal frame in a time domain according to the at least two original noisy signals, wherein the voice signal frame comprises a voice signal and a noise signal which are superposed in a time domain; the noise signal frame comprises noise generated when the voice signal is silent; determining the power of the voice signal and the power of the noise signal according to the noise signal frame and the voice signal frame; determining a noise reduction coefficient according to the power of the voice signal and the power of the noise signal; and based on the noise reduction coefficient, performing noise reduction on the original noise signals.

Description

technical field [0001] The present disclosure relates to the technical field of signal processing, and in particular, to an audio signal processing method and device, a terminal device, and a storage medium. Background technique [0002] With the continuous development of communication technology and Internet technology, the processing of multimedia information has become an important research direction of information communication. In order to achieve clearer and high-quality communication or data transmission, it is necessary to perform noise reduction processing on audio signals. Noise reduction processing can usually use filtering to remove noise components in the signal, thereby improving signal quality. However, in the process of noise reduction processing, it is often difficult to separate the noise component in the signal from the pure speech signal, so the noise reduction effect is difficult to meet the increasing user requirements.
