Abstract

The invention discloses an audio processing method, an audio processing device, a storage medium and electronic equipment. The audio processing method comprises the following steps: acquiring accompaniment audio frequency; extracting the audio characteristics of the accompaniment audio frequency, wherein the audio characteristics comprise at least one of continuity characteristic of harmonic intensity in time, abrupt silence block characteristic, Mel frequency spectrum characteristic, RASTA-PLP characteristic, PLP characteristic and frequency spectrum roll-off characteristic; inputting the audio characteristics into a preset model, and obtaining an output result of the preset model, wherein the preset model is a machine learning model; and determining the quality level of the accompanimentaudio frequency according to the output result. The quality of accompaniment can be effectively determined.

Description

technical field [0001] The present application belongs to the field of audio technology, and in particular relates to an audio processing method, device, storage medium and electronic equipment. Background technique [0002] Due to the limitations of early audio processing technology, the accompaniment could not be recorded separately during the recording process of many songs, so that the singer's voice was mixed in the original song released. In order to obtain the accompaniment of these original songs, in the related art, noise reduction processing technologies such as vocal separation can be used to perform noise reduction processing on the original songs, so as to obtain the accompaniment after the sound reduction of the song. However, in the related art, it is impossible to evaluate the quality of the accompaniment obtained after the song is muted. Contents of the invention [0003] Embodiments of the present application provide an audio processing method, device, s...
