Example Embodiment

[0031] The technical solution of the present invention will be described in detail below in conjunction with the drawings.

[0032] Such as figure 1 As shown, the present invention is a method for strengthening and separating multiple specific musical instruments in single-channel music and vocal separation. The method strengthens a total of 8 instruments including electric guitar, clarinet, violin, piano, acoustic guitar, organ, flute and trumpet Separation. The enhanced separation is achieved by a single-instrument separator and a three-layer multi-instrument combination intensifier. Among them, the first layer of multi-instrument combination intensifier can separate the sound of 2 types of instruments, that is, the second type of instrument combination intensifier. The layer multi-instrument combination enhancer can separate 4 types of instrument sounds, that is, the 4 types of instrument combination intensifiers, and the third layer multi-instrument combination enhancer can ...

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...
