A method and system for generating accompaniment

Abstract

The embodiment of the present invention provides a method and system for generating accompaniment. The method comprises: cutting the audio file into multiple audio slices of equal duration; extracting the audio fingerprint of each audio slice; slicing the entire range of the piano sound according to the duration of the audio slice to obtain the piano sound fingerprint of each slice ; matching the piano sound fingerprints with the audio fingerprints of the audio slices one by one; arranging and synthesizing the matched piano sounds according to the time sequence of their corresponding audio slices to obtain a piano sound accompaniment file. The method and system have high precision and wide application range, the synthesized song accompaniment audio is highly consistent with the original song, and the obtained accompaniment audio is accurate and of high quality.

Description

technical field [0001] The invention relates to the field of song audio processing, in particular to a method and system for generating intelligent pick-up karaoke accompaniment based on piano sounds. Background technique [0002] In the prior art, some audio playback software or audio processing software can be used to extract the accompaniment music from the original song alone. When current audio playback software or audio processing software extracts the accompaniment music, they often use the characteristic that the vocals in most songs are basically the same in the left and right channels, and use the method of directly subtracting the signals in the two channels to extract the accompaniment music. Remove vocals. [0003] There are at least the following problems in the prior art: the method for extracting the accompaniment of a song in the prior art will eliminate part of the accompaniment music while eliminating the human voice, thereby causing a decline in the soun...

AI Technical Summary

Problems solved by technology

[0003] There are at least the following problems in the prior art: the method for extracting the accompaniment of the song in the prior art will eliminate part of the accompaniment music while eliminating the human voice, thereby causing a decline in the sound quality of the accompaniment music

And the method for extracting song accompaniment of the prior art will eliminate part of the accompaniment music while eliminating the human voice, thereby causing the decline of the sound quality of the accompaniment music

And the method of channel pair subtraction is limited in scope, and some songs cannot use this method to extract song accompaniment

In summary, the song accompaniment extraction method in the prior art is laborious, and the sound quality of the accompaniment music is difficult to meet the high-quality accompaniment requirements in karaoke.
