Voice is often at the centre of a stereo recording so invert the phase of one channel and combine?

  that is the basic premise. there are also audio engineering effects to deal with such as reverb, chorus, delay and phasing due to poor input quality. lets not get into the likelihood of layered vocal tracks. TL;DR: you want the original raw vocal to do the best removal, and if you have that then you probably already have the tracked version of the mixdown so you can just mute the vocal layers. in my DJ days, you could just write a record label and ask for instrumental or vocal only demo tracks to perform mixes (this is how dj's became popular in the NYC scene). 80% of the time its a yes, and 90% of those vocal tracks were "audiomarked" copies so you could only make demos (but didn't stop people from using the non-watermarked part for a 15 second clip in their DJ mix. anyway, what i'm saying is that your method works for basic recordings. as you move up the production food chain you need to become more creative in your methods

  Most of the energy in an audio signal is at the center of the image, so in practice you don't really remove that much.
