Do it yourself acapellas or DIY refers to the procedure of manually separating a vocal-only portion of a music track from its instrumental counterpart; also known as vocal extraction. Lots of techniques, advice and help in here for creating that very special D.I.Y acapella. (NO REQUESTS)
a mistake a lot of people make is "applying TOO MUCH noise reduction". I can't stand those DIYs. It's ok if you hear a lil bit of the drums cause when you remix it, all the drums from the pella will be covered by the new beat you giving it. If you can't get a GOOD/MIXABLE DIY out of a song then DON'T DO IT!!!!
besides noise reduction, I also use the following. EQ, Hiss Reduction, FFT Filter.
good to see its all still going
another tip:
try out voxengo PHA-979
its good for getting phase adjusted perfectly when doing the ol' phase invert method
you can do it cool edit pro or audition:cool edit pro, you'll need two files...instrumental and vocals. both have to be the same quality. invert the instrumental and line it up perfect with the vocals and then bounce the mixdown tack.
Phase cancellation will never give you a clean acapella full stop.
There will always be bleed from other frequencies and you will always get that nasty phasing effect.
But Celemony have this new toy about to drop that claims to be able to do it. Apparently it can separate and isolate all of the different musical / tonal elements from any recording.
If what they are saying is true, it will be the biggest innovation since the sampler and will change the way we all work forever!

I've used audition a fair bit to pull out vocals, and have had varying results.
One thing that I did come across was that alot of older tracks (pre-digital, I think) were easier to get a good result from. I think it was because they were originally recorded with the vocals predominantly in one channel, and most of the instruments in the other one. I found some of the beatle's songs were like this, and the acapellas came out pretty clean.
TiMG wrote:heres an overview of the different methods used for extracting vocals...
1. THE PHASE CANCELLATION METHOD Get an instrumental of a song, invert the phase (sometimes refered to as flipping), and mix it with the original.. If done right everything besides the vocal is cancelled out. You can do this in any sequencer like cubase or acid.. The instrumental must be excatly the same time/pitch however. and mp3s might not work if they are badly encoded. Zoom right in to see the 2 waveforms next to each other (look for kick drum hits) and line them up.
2. THE KNOCKOUT METHOD using 'knock0ut' (http://www.freewebs.com/st3pan0va/) you can spectrally subtract one piece of audio from another. Start by extracting the centre mono of a track (soundforge or cooledit will do it with the pan/expand feature). then try and make an instrumental out of loops from the track and 'knock them out' of the vocal parts. This can work even if the instrumental isn't excatly the same as the song.
3. OTHER METHODS Besides these methods you can try Cool edits (now audition) noise reduction feature, which is very powerful. Analyse a bit of instrumental and get a profile (6000 or 4096FFT is a good size).. reduce than from the whole song. You can also try the soundhack spectral plugins and Voxengo's Transmodder to futher reduce spikey nosies like drums.. (don't ask me how .. its all trial and error).
You will NEVER make a totally perfect acapella with 2 and 3. You can however make something good enough to work in your mix.. USE YOUR EARS! LISTEN and learn and you might get somewhere

the first 2 methods are cool , but if u want good results steer clear of the third , it's tricky and usually comes out sounding horrible.
ive tried these method for a while now... didnt work in my case thought.... thats prob because i dont have the original instrus for those songs i want to get vocals out... ive used one method ... where i use a custom aux-cord from player/pc/whatever to recording device, it isolates some vocals...
maybe somebody could help me. I have the acapella for smooth criminal already. To help me explain what I need to do, here is a link to a you tube version of smooth criminal acapella.

skip to 3:22. now notice that during the chorus you hear michael going "I don't know. I don't know, yeah baby yeah something, something" and then later he screams "dagone it baby. dagone it baby"
I need to seperate those from the chorus.
can anybody tell me how to do that? I'd prefer for somebody to teach me to do it, rather than just doing it for me, because that way later on when I need something maybe I'll know how to do it.
