What methods can eliminate accompaniment harmony?

At present, there are several ways to make accompaniment tapes:

1. De-voiced part of original music: This method mainly adopts the method of subtracting the information of left and right channels, and common recording software such as Cubase, Nuendo and Cool Edit can be completed, and some civil and software are specially used for this kind of accompaniment production. However, the production effect of this kind of software is not good, and the hole effect and intermediate frequency defects are very serious. If the human voice has a strong reverberation, it will leave reverberation after processing, but it is basically impossible to eliminate the human voice for the original music recording as a non-audio track recording. Therefore, this production method is recommended for some occasions with low requirements.

2. When the music passes through the door, the original music is used, while the singing part sounds: This is slightly better, but it should be noted that the volume and frequency cannot be much different and changed when switching between the door and the aria part, and cross dilution can be used for processing.

3. In addition, the production of accompaniment: This requires considerable professional skills and professionalism, as well as certain professional equipment. At present, some students majoring in music production in art colleges are engaged in this kind of work. It takes time to find these people to do it. It usually takes five hours at the earliest. Second, it costs money. Third, for some people with poor skills and spirit, the effect can not be guaranteed. But the finished product is as good as the original.

4. Find the original accompaniment of the original song: This is of course the best choice, but it is usually rare and difficult to find.
