can u really do this on sound forge wat is the exact way to do it?

phasing method works fine enough... great post TiMG. Plus just equalizing a vocal out works just as good for me. Some of you guys are missing the point, you only need just enough quality to be able to mix in with another instrumental. In essence your masking the faults with the new mix. If it doesnt sound right, then its because its not in the right key and you probably shouldnt have mixed them together in the first place.

Oh btw maths dude, thats subtraction not inverse. inverse of (x+1)

is 1/(x+1)^-1 but u got the idea anyway.

Cheers!

This sound like an idea to try. Is there any software on the market thats affordable that will give me a better quality acappella? Id like to start a few mixes with the pella' so if the original mix is comin through strong it might not work.

is it possible to invert the phase with abelton live

cool, thanks

Yeah, I think you can do it with the Utility plug-in, but I can never get it method #1 to work with Ableton.

i tried the methods that were posted and the one that worked best for me was inverting the sound...i use audacity but i was wondering which program would be best for making acapellas. i plan to buy ableton live but want to know if it is as good as it seems.

thx

going 2 try now hope it work

I dont know if someone pointed it, but it has a way to get your accapela even cleaner.
As we know the phase cancelation is the best way to get a pela out of it's bed.
But even if this solution is the best, it has still some flaws. (ie: those low level sounds)
They are mostly acceptable, but in certain case, we just want to get rid of them.

First we have to understand where are those sounds/noise/artifacts are comming from. While mastering both the song with the voices,
and the instrumental, the engineer used the same settings that he got on the version with the voice on the version without.
Which means at the verry final stage he used the same maximizer on both version.

Those small sounds comming back after phase cancelation are coming from the version without the voice.
Fortunately they are the result of the same type of maximisation/limitation,
which means if we know how to go back (reverse engineering), we can fix that thing.
the instrumental version has less "things" to maximize which leaves more room for the sounds (artifacts) normaly "under the voice" to shine after phase cancelation.

Now that we know the problem, what is the solution?

The solution, as easy as it sounds, can be tricky.

reduce of 3 to 4 db both version, and add to both a compressor with a reverse ratio, such as 0.5:1, or 0.7:1... (that will "uncompress" them).
Keep the thresholds high enough. If you listen to the "canceled" version, the small sounds are not sounding like snare or hats playing at a low level,
but more like "the peak levels" of those sounds choped of their lower level parts.(they're mostly sounding like 8bit sounds)
Play on the attack and release settings till you get rid of the small sounds comming back.
When done add a maximizer back to the track, and put it's level up to what level you substracted at the begining.

nfect

I just can't do it. Simply put, I've managed to acquire all the software everyone talks about (ACID, Soundforge, FL7, wavepad, Goldwave, and the plugin kn0ck0ut) and all of them seem to not be working with what I want it to do.

I don't know where to find any other software that actually works any better becuase these programs seem top-of-the-line.

What am I doing wrong?

Not necessarily relevant, but I didn't want to start a new thread, but after vocal extraction, is there any way to convert an mp3 file to midi that anyone knows of?

Try using Melodyne I'm pretty sure you can trigger midi in there. I've only just got it so still learning the program

I have downloaded the KnoCkOut plug-in, but how Do I use it in Fruityloops? Or how do I open it? can someone please help

thnx

How the HELL do you do the inversion method? I'm seriously not getting it...

used the phase method, and it works and gives quite a good effect if u got a good instrumental and a high qual song

Wow, I didnt know you can extract acapellas your self, thats bad ass and I cant wait to try it out, but I started to think about the ingredients you need to create a DIY acalella. If you have to search for a good quality instrumental then most of the time you will find a good quality acapella with it (like a single 12"). So why go through the trouble of extracting the vocals. Im hoping someone to prove me wrong. Does any one know where to find good quality intrumentals and instrumentals only.

wow thank you
it sounds difficult

couldent you use the instrumental of the same song and then wined them down? it would be as easyer then tryin to find the same beat but diffrent instruments

I'm using ableton live, and i can't seem to figure out the procedure for phase cancellation. You guys said it's done by flipping the left and right bits of audio right? is this on the instrumental or the main track?

Yup, i tried the invert on the utility plugins. It works really well. I just didn't see the post above this page.

Can anybody send me the invers vst for virtual dj, or uplod it?

I did the phase cancellation in sound forge, found the vocal mix and instrumental of a proper - release standard encode from beatport.

Both tracks were exact in length, i magnified the wave form to split seconds on the kick drum and pasted them together exactly in time with each other (after phase invert of course)

All i could get was the kick drum frequency to totally eradicate..

I could even hear parts of the bass line, and pads, synths coming through.. it must be so hard, i dont know how more accurate you can get..

cheerz for the help in this thread!

shanoz.

The instrumental you use has to be a *literal* instrumental of the original - basically it has to be an instrumental created in the studio by doing nothing more than 'muting' the vocals. But sometimes an instrumental is also a remix - the levels of other instruments are slightly altered. In this case, the phase canellation method won't work! And it sounds like you're in that situation. However, the kick drums have remained the same, so only these have disapeared!

With that in mind, after doing what you've done above, you could then use the Knockout plug-in to isolate the centre of the stereo field (losing stuff panned left/right). Knockout also has a low-pass filter which I find is quite good at getting rid of basslines. Not so good at totally eradicating beats (without degrading the vocal as well), but you've already done that!

You still won't get a perfect Acapella (unless all your instruments are hard panned left and right), but more than useable in a mix probably.

ahhh thanx for the help man!
ill check it out and start to experiment

Learn something everyday

Here's a method I am experimenting with, works best for 80's acapellas: Try to find an "extended mix" which will have a lot of instrumental parts of the songs without the vocals. Line up sections of these along with sections of the same song with vocals, and use the phase cancellation method.

Now, if you have ACID (which is what I use) the easiest way to do this is to import both the vocal and instrumental bits into ACID, and make sure you have set the beatmapping properly. Then set the panning extreme left and extreme right on both tracks, so you have the vocals only coming out one side. Make sure you have lined up the tracks identically, then render the wav file. Open the wav file up in Sound Forge and do a phase cancel. If you did everything correctly, you should have an acapella.

Great post! Thanks for the information.
It's much appreciated and will be put to good use.

This is a good post! Great Info.

Wow, Ive been using protools for the past few years to extract the vocals from a song, but the bouncing takes a long time. Ive never heard of these programs but they seem worth a try.
