is there any way to change the voice pattern to make it sound like someone else is singing the same song?

Aside from re-performing it as Koz mentioned, no.

In order to do that you'd need two things:
1) a solo voice track.
2) a plugin to change one voice from another.

#1 you can get using the Center Pan Remover and just subtracting the original signal from the signal put out by that plugin. But #2 doesn't exist, the human voice is too heavily filtered by your lungs + throat + mouth to re-filter it and make it sound like someone else. It's even more impossible to make it sound like someone specific.

Only slightly off topic:

<<<#2 doesn't exist>>>

No, but I can think of ways of doing it. The tools are certainly there. Given that you have the voice track by itself, apply a nice FFT with the ability to manipulate the Fourier elements independently from each other. They have equipment that can take a bad answering machine and tell you with absolute certainty who it is with similar tools.

I imagine a nice engineering student should be able to handle that before lunch.

Koz,

You're talking about shifting the formats in someone's "voice pattern" to a different set of formats (you'd also likely need to change the fundamental frequency, but that's trivial). You can do things like that, it isn't very hard (it's basically just a very radical EQ). But there's more to a "voice pattern" than just frequency response. In order to be convincing, you'd also have to change the timing, pronunciation, accent, and breath noises. I don't doubt that it's technically possible, but it's still a ways off.

<<<I don't doubt that it's technically possible, but it's still a ways off.>>>

So you're not going to whip this out before lunch?

I'm crushed.

Heh, well I've been fooling around with Audacity, but can't seem to do it yet. Koz, when you were talking about the FFT, did u mean that it is possible to mess around with the voice pattern or something using that?

Can you actually change someone's voice with this?

No, but you can synthesize a "replacement" vocal.

It's actually a hybrid sampler/synthesizer - It sounds a bit strange (synthetic) as a lead vocal, but it's pretty good for backing vocals. Also, it has the advantage that it will "sing" for you any time of the day or night, sings in tune, does not have tantrums, and won't run off with the drummer

<<<Can you actually change someone's voice with this?>>>

No. That was a not so subtle joke to get Latham to write a tool that would do that.

He didn't take the bait...yet.

Ok well, I'm just still messing with it, but nothing. I'm trying to somehow access the voice pattern, but no luck. i.e., I'm trying to make Weird Al sing "Mind Games" which is by John Lennon, and basically, I want Mind Games to sound the exact same way , just with a different voice singing it. Is there any effect or something to do that? n I'm trying to make this go possible for any song, (if it is possible now).

An effect to change John Lennon into Weird Al ?
No there isn't (thankfully)
