Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] Usually when recording a record, it is recorded in the following way: first, the vocals are recorded into a mono track, and then this track is inserted into the stereo song accompaniment music, thus forming a If it is a complete song, if it is a mixed recording, the track of the human voice is usually averaged into the accompaniment music of the song. The sound waves of the human voice are the same in the left and right channels of the song, so if you want to eliminate the human voice, you can Subtract the waveforms of the left and right channels.

[0032] However, because the bass part of ...

Abstract

The invention is suitable for the field of a sound processing technology and provides an obbligato music generation device and a realization method thereof, wherein the method comprises the steps of: a. copying a song for two copies and respectively placing on an audio track 1 and an audio track 2; b. carrying out high-frequency filtering on the song in the audio track 1, remaining the high frequency section of the song, eliminating the voice in the high frequency section of the song, carrying out low-frequency filtering of the song in the audio track 2 and remaining the low frequency sectionof the song; and c. carrying out the audio track mixing on the high frequency section and the low frequency section to generate obbligato music. The invention can ensure that the obbligato music can be generated according to the song; the voice in the song can be eliminated, and the low frequency section of the song can remain and the effect of the obbligato music can be regulated according to actual requirements.

Description

technical field [0001] The invention belongs to the technical field of sound processing, and in particular relates to an accompaniment music generation device and a realization method thereof. Background technique [0002] Karaoke has become one of the favorite ways of entertainment for consumers, and the realization of karaoke is inseparable from accompaniment music. Many users are used to singing karaoke through the multimedia system in the family, so they need to be equipped with accompaniment music for singing songs. [0003] The accompaniment music is usually achieved by eliminating the original vocals in the song and retaining the music in the song. The existing methods such as frequency cutoff and noise gate control can eliminate the human voice to a certain extent, but it is difficult to achieve expected result. [0004] Therefore, there is a need for a technical solution that can eliminate the original vocals in the song and retain the music in the song, thereby g...
