Is there a feature in Soundforge that can extract vocals
from a song? If not, is there any software that can do
this? thanks.

Many have Tried and many have failed. Vocal Removal is based on Phase
between the right and left stereo signal. What you eccential have to
do...or at least try to remove the vocal is this. Select one side of
your stereo signal (either Left or Right does not matter), goto the
Process Menu and Select the "Invert/Flip" function. What you just did
was invert the phase of the channel you selected by 180 degress. Now
the Left and Right channels are out of phase with one another. what
eccentially happens when the stereo mix is out of phase is that
everything that was panned in the center of the mix is lost because
they cancel each other out. You also cancel out everything else that
was panned in the center also, like your bass and kickdrum. To
compensate for this you can now eq the mix and increase the bass
frequencies below 200Hz because the vocals are not that powerful in
that range, thus you raise the bass volume back up. What normally
happens though is that the main vocal is usually panned in the center,
but it has a stereo Effect on it like reverb, which means the reverb
part of the main vocal isn't panned in the center, so what your left
with is a thin sounding mix which sounds like it has someone singing
way off in the distance. Play around with this technique, maybe
you'll have good luck with your material, but once you do it you will
hear what I'm talking about. Good luck

Hi,

That is nearly impossible to do. The human vocal range covers a
frequency range that is also shared by the other instruments in the
mix. If you try to eliminate that frequency range, you will also be
detracting from the other elements. Brian said it best when he
said "Many have Tried and many have failed."

Many have failed, and I suspect a few more will do so again. =)

But having said that, heard a rumor amongst the remixers at Winter
Music Conference there is a company from Germany that has worked in
the scientific audio field for some time and made a claim that they
had a product that could do such a thing, and might be looking to move
it into the audio. But at about $9000 a pop for the gear, no one had
bothered pursuing it.

Also, another rumor (from a source who asked to be unnamed) has it
that Digidesign (Pro Tools) has been experimenting with trying to
develop a plug-in for just such a use and was hoping to have it out in
the first half of 2001. But at the time the idea was still in
research, so it might not live to even see (or have seen) alpha
testing.
