Remove Vocal

Do anybody know the theory, how the program removes vocal from the track?

Not gonna happen.

i believe it has something to do with lab rats, paella and a left handed screwdriver

voodoo



or phase cancellation....

Yarp, as Freak states, phase cancellation would do it but you would need to get hold of an accapella of the vocal first. Assuming one was available.

There are a few bits of software out there that claim to do this but they don�t do it particularly well.

i saw a video posted here of a tutorial where the guy would invert the instrumentals of a song, then line it up with the original track which would "cancel out" all the instrumentals, leaving just the vocals. is this true? or was that whole video a lie?

That's because it's not going to happen.

It's true, if the following are true:

1. You have the instrumental
2. The vocal version was not compressed after the vocal was added, i.e. the vocal version is simply an instrumental with the vocal added ontop
3. You can line the two up perfectly in an audio editor

1: may or may not be the case. If it isn't, give up now.
2: is very very rarely the case - nearly all tracks are given final mastering, which throws this out
3: you might be able to do, but it can be difficult.


So in short, the chances are very very slim.


The thread asked about REMOVING the vocal rather than obtaining it, in which case you'd use the acapella rather than the instrumental - the same still stands, you'd need to have access to the original acapella and the vocal version can't have been compressed after the vocal was added.

get a hold of the multitrack?

Some Audicity and Adobe tutorials

Yeah, there are a few things you can try there, but beware - most of them will only work every now and again.

The method used with Audacity there will only work if the vocal is the only thing centred, which it rarely is in electronic music - if nothing else it'll probably get rid of the kick as well as the vocal. Plus you're left with a mono version of the track, which you probably don't want.

The methods in Goldwave and Adobe Audition just use a feature in the program which uses a combination of channel position and filtering, which is usually far from perfect, but try them by all means.

Get in touch w/ the producer, ask for a dub version.

even if you did all that crazy cancellation shit or whatever, from my experience the resulting product will still sound like shit

all those vocal rip programs must be a sham then, im sure people buy them

Again, they use a combination of stereo positioning and filtering.

We're not saying it can't be done (well, I'm not at least), just that it's very rarely clean and would be noticeable that it'd been messed around with if you were to use a track with the vocal removed in a demo mix or something - you might just about get away with it in a club on a shit soundsystem.

If you got lucky and were successful in getting a reasonably clean vocal out of a track like that, you could probably get away with using that as an acapella in a mix, but again - 9 times out of 10 it would sound pretty shoddy on its own.


The main point is that there tends to be some naive misconception among some people that an audio file contains the different parts of the song separately and that you just have to "turn off" the vocal or whatever bit you don't want. You can get multitrack wave files, but they're very very rarely used and you certainly wouldn't be able to buy one from a download site. As audio files are actually just all of the instruments thrown in together, it makes it very difficult to separate them and in fact there is no known "perfect" solution, so any algorithms are based on guesswork.

buy the dub mix, cos even if you managed to take out the vocal of a track it would prob sound fairly bland. the dub mixes compensate for that with a few here and there sounds that the original mixes dont have.
