I now believe this sound byte was released in a followup file to the general 'sound.cdf' file. I think this is a way to encapsulate several sound bytes into a general file, much like a '.dll' file or '.pak' file. Extracting this byte without exact knowledge might prove bothersome, so I went out on a limb and contacted Meatwater on it.
I will continue to search out a file, or method, to accomplish this, but for now we will have to wait, or hope that someone in AH has the ability to extract it for us.
Converting it for AH use will be a no brainer, but I haven't any experience with hacking EAW in this way. Though, I know it is just a matter of knowing which '.cdf' file to use, and which address to start and end upon. Even Ultra Edit could do it, but knowing where to start, "Aye, there's the rub!"
