VOCAL EXTRACTION METHODS

thx!!

Hi I’m a newbie here, but I have been visiting this forum for a while.

As mentioned before in this topic, Celemony’s autotuning software Melodyne will release a polyphonic autotuner. Today the beta version has been officially released. See how it works here:

Some beta testers has allready tried to split up mixes with some succesful results.
Check out their experiences at the Celemony forum:

As I haven’t a Melodyne license myself, I have not been able to check how good results you can get.

[quote quote="Synthetik FM":cihg3eew]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![/quote:cihg3eew]

did anyone get this method to work? i tried it with a song and its remix but i got no dice. i’m hoping Synthetik FM can come back and supply us with a bit more detail. which channel is the one after applying the kareoke filter that i want to use, which ever one is more devoid of vox right? what other progs, windows or mac, have a phase cancellation option, is that the same thing as flipping/inverting in sound forge/audacity (respectively)? do i bounce the channel from the kareoke filter i want to use as a stereo image, i.e. copy the one channel to both channels, or do i just leave it in L or R when i line it up in Acid?
it’s the last phase cancellation that’s really getting me tho. reapplying the kareoke filter seems to have the opposite effect no matter how i conduct the overall process, it almost seems to make the song whole again, at least in one channel…
plz, lil’ help, if you’re still there duder, or anyone who got this method to work? much obliged..

Did know to method 1 but not 2 and 3 so thanks

about the only ways to make DIY-acapellas but they’ll never be the same as the original though.

really cool tip that mate . never thought of doing it like that

Example of this would be I am looking at getting the vocals of Breaking Benjamin – Without You. There is no "instrumental" portion of the song that is the same at the chorus/hook so I would not be able to use the "knockout" method on this part.

I have been quite sucessful in KnockOut verse 1 with verse 2, or chorus 1 with chorus 2, if the singing is the only difference between them.

Is there anyway to go about taking a entire track and cutting the vocals out of it and then inturn using that "instrumental" version you have just created to invert it against the original track?

There are some vocal remover/kareoke filters out there that remove certain frequences of the stereo centre. Sometimes you got a quite decent instrumental. Unfortunately, trying to KnockOut the original with the created instrumental has never been successful to me. You got to much muddy noice with the vocals in the end.

Ah so there are methods to take out acapellas and instrumentals! Awesome tips! 😉

Hey … sorry for being gone for awhile. The idea of this is you are using both mixes to get an instrumental version of one of the mixes, which you then overlay back with the original track to re-isolate the vox.

An example is my acapella for ABC’s "The Look of Love", using both the original 1982 mix and the 1990 mix. It’s available in the acapella library on this site. Here’s what I did:

Take both mixes, line them up in acid and beatmap them, make sure the vocals flange when they overlap. You might have to alter the start offset on one of the wavs.

Hard pan each mix left and right, so you get a different mix coming out each side.

Render a wav and use phase cancellation in Nero Wav editor using the karaoke filter. This is to knock out the vocals from both sides of the mix. You should end up with a mix featuring near instrumental versions of both songs, one out each side.

Choose one side of the mix, and in audacity, copy this side of the mix to the other channel. In my case I chose to use the original 1982 mix, which is now in near instrumental form out both speakers after you do this step..

Now take this wav back into acid, overlaid with the original 1982 vocal mix. hard pan left and right on both wavs, render a wav again.

Take the wav you just rendered, which should be instrumental out one side, vocal out the other, and reapply the karaoke filter in Nero Wav editor.

This should make the acapella.

I’ve managed a decent one to C-Ride’s "Money Round Here (feat. T-Pain)" but you can still hear too much of the music in the background. I’ve been trying EQ’s and filters to help but alas, nothing. I’m going to try some of these other options everyone keeps going on about and see if I can better results. I must say I underestimated the difficulty of producing one of these.

I mite try this out. thanks for the tips!

[quote quote="cbuffalino":3c9rdo1e][quote quote="TiMG":3c9rdo1e]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.

Doesn’t this method isolate the instrumental?[/quote:3c9rdo1e]

MAYBE

no

I’m looking for help. I’ve recently been trying to make my own acapellas because i’m looking for a sample but i cant find the acapella. I have tried the invert phase method and the knock out method. I’ve used audacity and cool edit pro and goldwave but i cant seem to come out with a decent enough acapella to use. I have watched multiple tutorials and read many articles on acapellas, trying the best i can to get this sample. Can anyone help me in anyway or maybe post this acapella???? Your time would be very appreciated..Thanks Soulja Boy – All The WAy Turned Up… with all of soulja Boy’s verses…

[quote quote="craig hamilton":1mt8cjh3]yo man tried the phase thing… used adob auditon to invert the wav… then did exactly as mentioned in example 1

this totally eliminated everything… what am i doing wrong???

thanks

HERE ARE THE REQUIREMENTS (Please do not post if you have not tried these):

1 .You have to have your original track.
2. You HAVE to have an instrumental track. (You can find an official one on web-sites like this one of you can DIY using the karaokesque filters in your DAW or you can do the looping the beat method)
3. Invert the INSTRUMENTAL track.
4. Assuming you already have both of the files in your DAW line them up in the multi track view of your software.
5. Adjust as needed to get the proper cancellation.
6. Export the multitrack file as your new Acapella .wav file.
