Can't 
But I think there are plenty of stuff about it out there. I'm looking for a formal definition of a phase vocoder. It lets you analyse a sound to extract information about a *lot* of different frequency bands (basically as many as you want), and then determines amplitudes and phases of all these frequency bands... You can then find peaks in the spectrum, and knowing about fundamental+overtone frequencies can (theoretically) extract sounds from a mix. There's a very formal definition of phase vocoding by Jean Laroche and Mark Dolson somewhere...
- the possibilities of phase vocoding are great - but there are some pretty annoying shortcomings too...

with this method you can extract groups of harmonics from a mix.,
but how do you know they belong to one sound source?????

Yep i think it is like if you have two glasses half filled with water. If you put them into one glass, and then divede them again, you have again two glasses filled half with water. But it is not the same water which it was before.

thats actually possible. but because of the same reason as in for audio it's not possible in any case. you need specific groups of nutritions to stand out. you can separate salad and meat but not salad and cucumber.

Probably this program could work to some extent, that is if you know what your doing. By using FFT-analysis it's possible to pick out single frequency components out of any complex sound, BUT if there are two sources operating on the exact same frequency, it's impossible. However, acoustic instruments usually release such a broad spectrum of sound, that they will most certainly mix with each other, thus making it impossible to recreate the separate recording tracks (they will most likely be distorted).
Love to try it though.

But the FFT-analysis I plan to use hogs computer resources pretty bad...

Depends on the size of the FFT bin's.
To get good resolution, you must have very large FFT-bins, and since they come in multiples of 2 (2^x) they tend to grow pretty fast.
No less than 65536 would be recommended (thats 2^16) |

It doesn't really look like this application is fit for sound engineering.

Or else ppl can always send the tracks that they want to be puted apart to CSI.
''-Can u clean it up?
-yes ofcourse im gonna filter out the frequencys and then pass it in the enchancers, now iv got the frequency right lets take of the distortion and the noise
-what is he saying?
-i think it is..... wait yes he says
IM gonna kill you
-lets call the judge to get our warent''
LMAO 
So fucking unreal !!!!! all the cops in that serie are SUPER SOUND ENGENIERS.

I think hiring CSI to reverse engineer a track, would be really really expensive.
