Is there a way to extract vocals from a song?

It is possible to remove vocals in Audacity, Moises, or any other voice extraction tool because the voices of the songs in stereo are recorded between the instruments, making the removal possible. Still, it is a job that depends on the quality of the audio.

How do I completely isolate vocals from a song?

Duplicate track, 2nd track swap the stereo channels, and then effect invert. Inverting your phase, or mirroring your audio. If you then play your 2 audio tracks together, you will cut out your vocal.
