Song climax fragment identification method and device

Abstract

The embodiment of the invention discloses a song climax fragment identification method and device. The method comprises the following steps: sampling an audio file of a song, according to the note time value and the rhythm type of the song, dividing the sampling data of the song into sampling data of a plurality of audio paragraphs, obtaining a chord corresponding to the audio paragraph accordingto the sampling data of the audio paragraphs, determining a chord period included in the climax fragment according to the chord trend of the song and the chord corresponding to the audio paragraph, correcting the chord period included in the climax fragment according to the lyric data of the song to obtain a chord period included in the climax fragment, and finally identifying a part, corresponding to the chord period included in the climax fragment after correction, of the song as the climax fragment of the song. According to the method and the device, the climax fragments of the song are identified based on essential factors of the song, such as note time values, rhythm types and chord trends, so that the identification accuracy of the climax fragments of the song is improved.

Description

technical field [0001] The present application relates to the field of song processing, in particular to a method and device for identifying song climax segments. Background technique [0002] The climax of the song allows the user to quickly preview the song and form a first impression of the song. Therefore, many music players provide a trial listening function for the climax of the song in order to attract users more quickly. [0003] When identifying the climax segment of a song, by analyzing the lyrics, time series characteristics, spectrum characteristics, etc. of the song, a standard algorithm process is used to extract the segment, especially the climax segment, but these methods are only from the external expression of the song, such as Lyrics, pitch, spectrum, etc. to indirectly extract the climax segment does not fundamentally understand the song, so there will be errors in the extraction of the climax segment of the song, resulting in a lower recognition accuracy...
