Audio file processing method and device and storage medium

Abstract

The embodiment of the invention discloses an audio file processing method, and the audio file processing method comprises the following steps: obtaining an audio set which includes a plurality of audio files, the audio set being divided according to audio attributes; segmenting each of the audio files into M audio frames, wherein M is a positive integer greater than or equal to 2; extracting a plurality of feature combinations of each of the audio frames, wherein each of the feature combinations includes a first energy value corresponding to a frequency spectrum brightness, a second energy value corresponding to a first frequency spectrum roll-off, and a third energy value corresponding to a second frequency spectrum roll-off; inputting the plurality of feature combinations of each of theaudio frames into a preset model to obtain a ranking value of each of the audio files; and determining a target audio file from the audio set according to the ranking value of each of the audio files.For a group of audio files with the same content and different tone quality, the tone quality of the audio files can be identified accurately and rapidly, which is beneficial to the optimization of amusic library.

Description

technical field [0001] The present invention relates to the field of multimedia technology, in particular to an audio file processing method, device and storage medium. Background technique [0002] With the rapid development of the Internet, the multimedia field is also developing day by day. Users can not only obtain information from the multimedia field, but also experience audio-visual effects from the multimedia field. Multimedia includes video and music. Taking music as an example, the sound quality will determine the auditory effect of the song. Excellent sound quality will make the auditory effect more realistic, without the modification of other external factors, it has a very immersive feeling at the scene. However, poor sound quality will make the auditory effect unrealistic, and it will not be possible to have the feeling of being on the scene, so users often choose songs with good sound quality to experience the auditory effect. [0003] During the research a...
