Hi All, I've got this audio file (99% certain it contains audio) it ends in .sound but is supposed to be an AAF type file... I cannot for the life of me figure out what software to use to open it. It comes from a game I'm trying to mod - just change sounds over as they are messed up.
Can anyone here identify the header? Or find a way to open/play/convert it to wav?

many thanks
