Is is possible with CE2K to isolate the vocals on an existing song. Kinda like making the oposite of a kareoke track.
I hope this made sense.

Hey Plan..I would still recommend doing the search as Beetle suggested..but just to save you some time: essentially, without a multitrack source, the answer is NO!
Here's my favorite analogy...Consider a cake. Is it possible to remove the eggs once it's been baked? Of course not. Unless the vocals are hard panned to one side (with nothing else) Or, every instrument is in the center but the vocals are hard left and right (which is unlikely, and you'd still have the echo of reverb returns) this is virtually impossible.

I bet Syntrillium would like a dollar for every time this one has cropped up :-)
What interests me is why someone would want to do this in the first place? To provide their own backing to an existing name artist perhaps?
If so, I suspect they would be disappointed with the results, as the singer would have tended to phrase with the original track and this would force the new backtrack to follow something along the lines of the original performance - unless a highly disjointed performance were being sought.

There are several reasons why some people would want to do this in addition to what Grame suggested, like, radio using a popular song's instrumentals for radio spots, kareoke, musicians accompanying with thier own playing, rappers rapping, and hip-hoppers trying to sample beats, all of which raise issues of copyright infringement if meant for public performance and/or sales.
Be careful out there!

The reason I was asking, was I had a little project I wanted to play with. It would be neat to put a cover artist on the same track with an original artist. Evan if the tempos were off, and you could'nt get all of the music off of one track, it would still be neat to play with. Kind of like the Nat King Cole/Natalie Cole duet.

All of these things are based on removing the vocal and leaving the music - possible, but not always very effective, depending on the source material.
What plan9 wanted to do was to remove the music, leaving the vocal. It was thereason why anyone would want to do this that I was curious about. Since he has now replied, I know what his reason was. But this is a question which has been asked so many times in the past, I can't help but feel that there must be people with other reasons for wishing to do it.
Whatever the reason, it can not be done!

Isolating the voice is impossible, however isolating the phase information is not. Assuming that the voice in the track is in phase in both channels, you can extract the frequencies using phase comparison. I've done some of this myself, however it is experimental. It removes 99% of the frequencies which appear in both channels which are in phase. this also works for signals which are 180 degrees out of phase AKA rear channel. Coded in C, I used this to simulate an AC3/THX decoder. I currently am able to decode Center, left, right, rear left, and rear right channels using my code. If you want more information email me:
