Abstract

The embodiment of the invention discloses a human voice and accompaniment separation method and related products, and the method comprises the steps: carrying out the Fourier transform of a mixed audio frequency, obtaining a first spectrogram of the mixed audio frequency, the mixed audio frequency being a single-track audio frequency, and the mixed audio frequency being obtained through the mixingof human voice and accompaniment; inputting the first spectrogram into a neural network to obtain a second spectrogram corresponding to the human voice and a third spectrogram corresponding to the accompaniment; performing inverse Fourier transform on the second spectrogram according to the first spectrogram to obtain the human voice; and performing inverse Fourier transform on the third spectrogram according to the first spectrogram to obtain the accompaniment.

Description

Technical field [0001] This application relates to the technical field of audio processing, in particular to a method for separating human voice and accompaniment and related products. Background technique [0002] In recent years, the speed of music creation has exploded, with hundreds of original songs being produced every day. However, the karaoke accompaniment and karaoke lyrics corresponding to the original song cannot be provided to the karaoke system in time. Most of the accompaniment library in the karaoke system requires professionals to record, and the recording efficiency is low and the cost is high. Therefore, in order to improve the recording efficiency, through the acoustic accompaniment separation technology, the singing voice and accompaniment in the original singing song are separated, and the separated accompaniment is recorded into the karaoke system. [0003] However, most of the existing technologies currently focus on the separation of audio partners of dual...
