Abstract

The invention relates to artificial intelligence, and provides an audio noise reduction method and device, equipment and a storage medium. The method comprises the following steps: pre-processing noise frequency to obtain frequency spectrum information, processing the frequency spectrum information based on a frequency domain signal processing network to obtain frequency spectrum mask features, acquiring time-frequency features according to the frequency spectrum information and the frequency spectrum mask features, processing the time-frequency features based on a time domain signal processing network to obtain time-frequency mask features, generating a predicted audio according to the time-frequency features and the time-frequency mask features, adjusting network parameters of a preset learner based on the predicted audio and the pure audio to obtain a noise reduction model, acquiring a request audio, and performing noise reduction processing on the request audio based on the noise reduction model to obtain a target audio. According to the method, the noise reduction accuracy and real-time performance of the request audio can be improved. In addition, the invention also relates to a block chain technology, and the target audio can be stored in a block chain.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to an audio noise reduction method, device, equipment and storage medium. Background technique [0002] In teleconferences such as remote office calls, there is a high demand for real-time and accuracy of audio noise reduction. However, in the current noise reduction method, information at the frame level is usually used in the complete voice sequence processing, resulting in inefficient noise reduction. [0003] Therefore, how to improve the real-time performance and accuracy of audio noise reduction has become an urgent technical problem to be solved. Contents of the invention [0004] In view of the above, it is necessary to provide an audio noise reduction method, device, equipment and storage medium, which can improve the accuracy and real-time noise reduction of the requested audio. [0005] On the one hand, the present invention proposes an audio n...
