That sounds encouraging. What to you mean by "pre and post" (sorry if that's an
obvious question to you)?

I think you're right. There's nothing universal about making noise and actually
meaning something ;)

Pre and post meaning the start and finish of a recorded wav or region. Example being the first few, and the last few, milliseconds or so. Most of this would be obvious to the ear, so i can imagine a means to edit this could be mechanised in some way. (Being
careful, of course, not to dehumanise the original recording too far.)

Thinking further about modules, you might consider the inclusion (should you try this) of a user definable module, in which the user could set parameters. Consider the lone singer at home, or the voice over artist who uses the same 'voice' on a regular basis. They would tend to form phrases, and speech, in the same way, more often than not, including mouth noise, nasal, etc.... (Big generalisation here, but to get the point across...)
If the user can use his or her own template each time as a start point, then it might prove more efficient, and definable, as a mechanised process.
(Alex singing module, Olivier talking module, etc)
