I have heard about plug-ins (don't know for which program) that will tune someone's recorded voice if they are off-key. I know there are digital boxes that will do this but assume that there are also plug-ins to do the same (I saw it in some video making fun of how easy it is to "manufacture" pop stars) Does anyone know anything about these plug-ins or the program they can be used in? I've tried searching the forums but really didn't know what I was looking for.
