Go to Effects, Filters, Center Channel Extractor, and press okay. Some other EQing helps after that, but for the most part that usually gets you a pretty good base if you can't find the original.

or you could go ask the gorgotron...

@ this thread

Hmm not to be an asshole or nething but here's a quote from a guy on dogsonacid.com Link to Forum Never really tried that personally, and never will seems like an awful lot of trouble for something trivial

Doubleclick:
"You can, but your thing is going to be tricky. If you can find a bit of the backing which exactly matches the part you need, it can be done.

Here's how you make an accapella from an instrumental and the original IF the instrumental is exactly like the main version just with the vocal muted:

Load one channel of your sequencer with the main mix and the original into the other. Zoom in very, very close on the waveforms to ensure they are anchored to play at exactly the same time (i.e. identify a precise point in the wave of the first kick drum, or some other significant sound). Select the instrumental waveform and Invert it.

A sound played against an Inverted copy of itself will result in silence, because the waves cancel each other out. In the example above, the music will be cancelled out leaving the voices untouched. It's not quite that simple; you need to fiddle with the relative volumes to get rid of more of the small amount of music that remains (because the wave in the instrumental will be louder than the backing in the main mix).

You will probably still have a tiny amount of music left behind, but this can usually be removed with a little hi and lo pass filtering, and/or using Parametric Eqs to isolate the eqs of the troublesome sounds and reducing them in dBs. Isolating the frequencies isn't too hard; whack up the boost to +18db and maiximum "Q" so you can hear what you're doing, slide through the frequencies until your sound rings out ultra-loud, then cut it to -18dB and adjust the "Q".

Then bounce the result, and there's your accapella."

already been mentioned in a previous post, but as i said then, it is so hard to do, that a n00b that would ask such a question wouldnt be able to. it takes 1 hour just to get it right aligned with the oterh part as you practically need it right by a nanosecond..

edit: sorry, just me being a prick.. it was indeed another way suggested above, but this is actually harder..

Actually, if you have two copies that are EXACTLY the same but one has no vocals, then it would be quite easy to align them properly and invert one waveform to isolate the acapella.

Unfortunately it is never that simple. You might have two tracks that *sound* identical except for the vocals, but in reality they will each have gone through several processes that significantly change the waveform during or after the mixdown (compressors, stereo expanders, tubes, brickwall levellers, reverb, etc.)

At the very least, both versions will have gone through a mastering compressor/leveller, and think about the result of that - when the vocals are compressed with the rest of the track, it will lower the overall volume of the other instruments, and not in a linear fashion that you can compensate for when you try to do your inversion "rip". The waveform of the "dub" version is NOT identical to the sum of the dub and the acapella, therefore the sum of the vocal version and inverted dub will not give you the acapella. Compression, stereo expansion, and other processes that change the track this way are NOT reversible.

Thus, in all seriousness, it is simply not possible to cleanly rip a vocal from a track, no matter what tools or materials you have at your disposal. You might be able to get a version that's "good enough" for the typical audience, but keen listeners (especially other producers) will be able to tell the difference very easily.

And do people really need to be reminded that even if it could be done successfully, it is still completely unethical? Trying to rip vocals from a full track goes far beyond the realm of harmless sampling and editing - you're doing this with the express goal of taking credit for somebody else's hard work.
