You know having taken many audio classes in college I can say on some authority, I have a really hard time believing this is possible. Removing sounds is a matter of frequency slecting, then toning out said frequency. So far all you've done is claim what you "want" to do, or "if" it is possible. Please do yourself a favor, post something thats already done before announcing it, if you have a selection of film that has all the audio elements removed and seperated, then show us cause until then I chalk this up to wishful thinking. Sorry for being the voice of disbelief on this one, but I just dont think what you want to do is possible.
