How to remove voice from audio files and leave only music?

I've seen a lot about eliminating voices from music materials. In fact, no software can completely eliminate human voices, especially professional records, songs and accompaniment made by professional companies in Europe and America, which are mixed together and cannot be handled at all.

The records or audio files produced by some domestic production companies can be processed to a certain extent, but only for family entertainment, and adobe AUDITION can be used for processing.

The method is as follows:

For example, go to an audio file and then Edit-Convert Sampling Mode. In the pop-up dialog box, select mono in the Channel option, and set the left and right mixing ratios to 100% and-100% respectively to partially remove human voices. This is the best way.
