Multiple specific musical instrument strengthening separation method in single-channel music human voice separation

Abstract

The invention relates to a multiple specific musical instrument strengthening separation method in single-channel music human voice separation. The method can used in strengthening separation of eight types of musical instruments, i.e., an electric guitar, a clarinet, a violin, a piano, a wooden guitar, an organ, a flute and a trumpet; and the strengthening separation is achieved through a layer of single-musical-instrument separators and three layers of multi-musical-instrument combined music enhancers, the first-layer multi-musical-instrument combined music enhancers can separate two types of musical instrument sounds, the second-layer multi-musical-instrument combined music enhancers can separate four types of musical instrument sounds, and the third-layer multi-musical-instrument combined music enhancers can separate eight types of musical instrument sounds. A DRNN is used as a core of the single-musical-instrument separators, and different DRNN models are established for the different single-musical-instrument separators; a BP network is taken as a core of the multiple musical instrument separators to achieve separation of the multiple musical instruments at the same time; and, finally, a construction method aiming at different training samples of the single-musical-instrument separators of a system is provided. The method is simple and flexible and has high practicability.

Description

technical field [0001] The invention relates to the field of separation of accompaniment sound and human voice of single-channel music, in particular to a method for strengthening and separating multiple specific musical instruments in the separation of single-channel music and human voice. Background technique [0002] With the continuous development of computer signal processing technology and Internet technology, the singing separation of single-channel music has attracted more and more attention. Since most of the music signals that people can obtain in reality are single-channel music signals, it is difficult to obtain a signal that separates the accompaniment sound from the singing voice. However, having pure accompaniment and singing plays a very important role in reality. Single-channel music and vocal separation technology is used in many systems, such as the acquisition of music accompaniment in the KTV system; in the music retrieval system, the retrieval system b...

However, these methods do not take advantage of the different characteristics of different instruments to enhance the separation of these instrument sounds.

And so far there is no human voice separation system that can strengthen the separation of a variety of specific instrument sounds.
