Embodiment Construction

[0117] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with some aspects of the invention as recited in the appended claims.

[0118] The present disclosure provides a noise reduction processing method, which is applied to a terminal. In this method, when noise reduction processing is performed on the audio in the media file, the acoustic scene type to which the first audio information belongs is determined by an acoustic scene classification model, so as to realize the classification of the acoustic scene of the first audio ...

Abstract

The invention relates to a noise reduction processing method and device, a terminal and a storage medium. The method comprises the following steps: acquiring to-be-processed first audio information; determining a to-be-processed spectrum feature of the first audio information; determining an acoustic scene type to which the first audio information belongs according to an acoustic scene classification model and the to-be-processed spectrum features; and performing noise reduction processing on the first audio information according to the acoustic scene type to obtain second audio information after noise reduction. According to the method, the first audio information is subjected to noise reduction processing in different modes according to the acoustic scene type, so that the noise-reduced audio information after noise reduction is accurately, efficiently and simply obtained, a user does not need to know excessive software operation knowledge and knowledge in the sound field, audio processing can be well achieved, video processing is well achieved, and the user experience is improved. And the use experience of the user is improved.

Description

technical field [0001] The present disclosure relates to the technical field of neural networks, and in particular, to a noise reduction processing method, device, terminal and storage medium. Background technique [0002] In the related art, when noise reduction processing is performed on the audio in the video, it is generally necessary to import the video to be processed into professional software, and the user can perform manual noise reduction processing on the audio in the video through the professional software, which requires the user to perform noise reduction processing. Only with professional software knowledge and knowledge in the sound field can noise reduction processing be realized, and the user experience is poor. SUMMARY OF THE INVENTION [0003] In order to overcome the problems existing in the related art, the present disclosure provides a noise reduction processing method, device, terminal and storage medium. [0004] According to a first aspect of the...
