To remove a voice from a recording is easy. You cancel out the middle channel by overlapping one of the two channels with an inverted copy of the other. But the question no one thinks about is how to do the opposite. How do you keep only the voice in a recording? I've tried to overlap the instruments only (after removing the voice) over the original recording and nothing happened. Any ideas ?

O.......K......
What do you mean. If you can do it one way you must be able to do it the opposite way too. Anyone more creative dare to answer?

Hi all, hi no one,
try out the MS-Mixer tool of DrowZ2,
downloadable from
http://www.audiotechcorp.com/
and get an impression, how voice removing or voice ripping can be realized, use phase inverting and eq.
I you have enough time and you will do pedantic work then I suggest working in multitrack view, splice out vocal piece, analyse in spectralview where the "hot" frequencies lies, transform it by FFT or another filter algorythm and so on ... .
CEP give you all the possibilities to tweak it to best results.

What I mean is that it is impossible - you obviously have a problem with that concept.
I'm as creative as the next man and I would hazard a guess that I've been at this game for a lot longer than you have been alive. If you had any understanding of the physics involved behind the process, then you would be able to work out for yourself just why what you are asking can not be achieved by phase inversion and mixing. It's not even 100% effective when removing the vocal, except in a few cases.
OK - by careful filtering and the like - you might be able to attenuate the music, but you will likely play havoc with the quality of the voice.
So, I stand firm and will state - yet again - that it is just not possible to remove the music and leave just the voice.

Hello no-one. I will agree with Graeme and I would also like to add that this question HAS been asked many times. Just search the forum for voice removal, vocal removal, remove voices, etc. This probably comes up one or twice a week. In fact, a recent thread discussed this in relation to a popular record that attempted this technique. The concensus was, that of course, the voice was not isolated by any means, there were still remnants of music, and as Graeme mentioned, the voice that was present was excessively EQed.
