Fan Dubbing(?)

Maybe if you have a bunch of people who are passionate about the series that's being dubbed and those people can actually act, you might be able to turn out something decent, or even better than a lot of the dubs out there. There are a few good ones, and even some that I almost prefer dubbed. Almost.

Splitting the voices from the rest may be possible but dont hope too much for it. The way to do it is the following:

You invert the left or right stream of the sound (stereo sound consists of two different streams as you know). This can be done with quite some programs and one is Cool Edit. Now that it is inverted you merge it with the original sound and all sounds that are existent on both the right and the left stream will be neutralized while youll keep everything else. The shitty part is for one; the voices dont necessarily need to be existent on both the streams and if they arent you cant remove them. Another problem is voices arent the only thing that usually appears on both of the streams thus you may end up removing more of the sound than just the voices.
If you want to remove all except for the voices your in deep shit but logically thinking you could remove everything that isnt existent on both the streams and hope the voices are what remains. How to do this is for you to figure out because I have never done such a thing and dont have a clue on how to.

Yeah without the separate channels method, it's impossible (or, more accurately, extremely hard) splitting voices from non-voices. And won't it be common for there to be a changing mix of voice and non-voice on each channel?
