Soundforge Enquiry

[Robbie Chopper]

does anybody know how you pull a vocal from a track in soundforge so that you are just left with the acapella and nothing else ??????
a mate of mine showed me how to do it once but now ive forgotton, I think it had something to do with using the "invert/flip" function, then saving it , then laying the inverted version and the original out in Sony Acid as two seperate tracks (one on top of the other) then when you play them together you get the acapella only.....????

Ive tried this but i must forgetting something because it doesnt work when i do it

Ive also got Ableton Live 5 if anyone knows of a way to do it in there ??
Cheers,
Robbie

Well, there's a certain truth to it... the only way this can be done is if you have a flawless digital copy of the tune and also a flawless digital copy copy of the instrumental version. And when I saw digital, I don't mean a wav rip of a vinyl, or an mp3 lol

If you have both these and invert the phase of them and then overlay the two tracks perfectly, then everything will vanish except the vocal.

You can make some half arsed attempts to do this by inverting the phase of one channel of a tune then mix it down to mono. You might be left with a vocal and a bit of background shit, but really it depends on how that track has been mixed in the studio.

The phase cancellation method is the only way this can be done properly, and I can't stress enough about how accurate the overlaying needs to be to make it work. They have to line up exactly to the sample - and there's 44,100 samples every second. Even if it's a bit out it won't work which is why vinyl rips or mp3's won't do.


A good way of thinking about this is like I've said before in a couple of other posts about this subject... If you bake a cake, can you then take the eggs out whole?
