extracting vocals (revisited)

this comes up about once a month. so sorry if it annoys anyone here.

i need to extract some vocals from a cd single but do not have the instramental(or know of an instrmental release) to use to phase cancel the music out of the vocal mix.

is there any way i can use phase cancellation to allow accapella creation from just the vocal mix of the track? for example, maybe cut the track into its seperate right and left channels and use them in a way to phase cancel and use the fact that the vocal is centered in the mix?

opinions?

if the vocal is the only thing on dead center then yes...(not sure about how exactly, but I've heard somewhere it can be done).

Another thing to consider might be playing with EQ, sidechain etc...

it's an easy way how to get half-decent workable remix material...check my Gaudino's Destination bootleg.

No, it won't work. There's alot of other stuff that are centered in the mix as well as the vocal.

You can use an instrumental part of the track to cancel it out, but the instrumentation will most likely not be the same.

i hoped no one would say that

but i dont mind if there is a little bit of other stuff, i can imagine it might kill most of the stuff seeing as a lot will not be centered. ill prob be left with the kick for sure, as well as some efx. when playing two identical lined up versions (one phase inverted) it just cuts the whole thing and i get no sound at all.

how can i go about using phase cancellation when using two of the same tracks(both vocal mixes)?

you invert only one side ... like one of the stereo channels...let's say you invert right...and play left normally.

Good grief.

Fucking hell.

Just. Fucking hell...

and sum left and right together after that, so you get a mono result.

That wont work. The bottom line is that what richg101 wants to achieve is impossible. I can't even be arsed to elaborate at this point. Anyone curious can run a search in this forum.

To the Moaners/'Bored-Disgruntled-Tranceaddict-Police':

why bother reading this? go read something else if you find the thread upsetting

thanks for the helpful advise everyone who shed some info on the matter.

i got a feeling this should give the instramental? not the vocals is this right?

then i suppose i could use the resultant instramental(inverted) to cancel the music from the original vocal mix....

assuming the vocals are centered


ps. Posters on TA never want 'it wont work' from people who assume things are impossible. they ask for advise from people who might know, or have some of their own ideas that might not be of direct use, but might open up ideas of myself and others. eventually a collaberative effort might result in something useful. if not, something else might come out of it. lets be more positive and make the forum warmer and more enjoyable to frequent.

Nobody finds this thread 'upsetting', they're just telling you the truth. But I guess the truth isnt what you want to hear? Would you rather everyone just lied to you and pretended it was possible?

We dont assume its impossible, we know its impossible, the two methods mentioned here already (inverting the instrumental and using the stereo difference) are the only ways of getting the vocals alone, if neither of these work there it is impossible.

well, if i can make an instramental from what i have, then maybe i can use it to cancel out the instarments on the original...? ill make it work

Well, Rich, my reply was just a polite answer to your question...I highly doubt, you'll ever get a half-decent result!

2 years of pointing this out to people on this forum and it still hasn't sunk in. If you knew how destructive phasing works you would know why it is impossible with what you have and you would save yourself time and hassle.

But what the fuck do I know right? Make the mistake yourself and learn from it. It will probably work out for you better this way but you sure as hell won't isolate any vocal or instrumental track.

i knew total isolation was not gonna be possible, but so far i have found i am able to seriously reduce levels on a lot of the music. and a lot more than if i were to just use eq and cutting around. its hard to remember which tracks to phase reverse seeing as im using six tracks which are all eq'd differently.

ps. i was not popping at all the negative responses, just the ones i expectecd to get.

merry christmas chaps

ive benn here and it rarely if at all results in usable material.

you're right about the result being the instrumental. Inverting it and pasting over orig doesn't leave the vocal though, as the instrumental gained before was hardly clean.
