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)
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.
I have sony acidpro 6.0...I have Intrumental and original track lined up perfect I get stuck on the step listed below...help me please...

I discovered another method: you need two mixes of the same song, completely different except for that the vocals need to be exactly identical. Line up both mixes in acid, make sure the vocal lines up (you should hear a flange), hard pan left and right, render a wav.
Do a phase cancellation on the mix to eliminate the vocals. I use Nero Wav Editor's karaoke Filter, which will basically create instrumetal versions of each mix in each channel. Choose the channel you want to use, then line up the instrumental mix versus the original mix in ACID again. Render a wav, do phase cancellation again, and you have isovox!
yes, the vocal pitch has to match exactly with the pitch of the original mix, so you may need to pitch it down or up in ACID if they don't match.
Keep in mind, it works best if the only common elements both mixes have are the vocals, and maybe some backing (no bass or percussion). I have isovox for ABC's "The Look Of Love" which I will be uploading as soon as uploads are restarted ... on this one, I used the original mix paired with the 1990 mix (both taken from their greatest hits comp) ... the only common elements are the vox and strings, and that's what ended up being isolated.

I'm trying to get an acapella for Kings of Leon "Manhattan". It's become an obsession! lol
It can be done, depending on the structure of the song.
As a reference, check out my acapella for Eurythmics "Here Comes The Rain Again" which was done entirely with no instrumental. What you are looking for is sections of the song which are instrumentally identical or similar to the vocal parts of the song, but without vocals, or with different vocals. Most importantly, you want the beat and bass and other lower frequencies to be as close as possible. Line these sections across from each other in ACID, hard pan left and right, render a wav, then use the Karaoke filter in Nero Wave editor.
It won't always be perfect, but you can get good results.
cna this work in audacity using an instrumental flipping the channels and mixing it with the original? and is that what they mean by invert the phase? just switching the left and right channels with each other?
just to say thanks for the info guys. the main reason i got into this site was to learn more about 'pellas. i look forward to getting the hang of this and sharing my results.
i have a question regarding vocal extraction methods. I use ableton to make my tracks and i've tried using audacity to rip acapella's but the program has been on the fritz lately. does anyone else know a good, FREE, software editor that i can use for DIY acapella's on Mac's. Would be very appreciated.....
