Noise reduction method and device, electronic equipment, storage medium

Abstract

The invention relates to an audio noise reduction method and device, electronic equipment and a storage medium. The method comprises the steps: performing windowing and framing operation on a currentaudio signal to obtain a plurality of audio frames; respectively executing Fourier transform operation on the plurality of audio frames to obtain original amplitude information and original phase information of the plurality of audio frames; inputting the original amplitude information of the plurality of audio frames to a pre-trained noise reduction model to obtain a noise reduction coefficient output by the noise reduction model; respectively performing noise reduction operation on the original amplitude information of the plurality of audio frames by using the noise reduction coefficient toobtain noise reduction amplitude information of the plurality of audio frames; respectively combining the noise reduction amplitude information and the original phase information of the plurality ofaudio frames, and executing inverse Fourier transform operation to obtain a plurality of noise reduction audio frames; and performing windowing and splicing addition operation on the plurality of noise reduction audio frames to obtain and output a noise reduction audio signal. According to the invention, the noise reduction coefficient can be used for performing noise reduction operation on the original amplitude information, thereby achieving the purpose of suppressing environmental noise.

Description

technical field [0001] The present disclosure relates to the technical field of the Internet, and in particular, to a noise reduction method and device, electronic equipment, and a storage medium. Background technique [0002] With the continuous advancement of science and technology, there are more and more types of applications in electronic devices, and many applications involve audio signals. For example, in short video applications, audio signals are involved when users record short videos, and when users live broadcast Audio signals will be involved, audio signals will be involved in real-time transmission in real-time communication applications, and so on. [0003] Since the environment in which the user uses the electronic device is relatively complex, the audio signal not only includes user audio but also includes environmental noise. A noise reduction method is needed for this purpose in order to reduce the ambient noise in the audio signal. Contents of the inve...
