I'm working on a dvd for a group of friends, the picture quality is good but I'm having a few issues with the audio. One of the group has had a lot of experience working on music recording having produced one or two albums and worked for many years as a musician. Now he can work wonders downplaying embarrasing bits on audio recordings but wants the raw files as wav's, now converting them into wavs is not a problem it's what do with them afterwards that is my concern. When I come to make the dvd could I simply use the wavs instead of the original dobly ac3? Would the wavs give a similar quality or am I better using something completely different when I come to make the dvd? I'm going to use dvda 4.5 and I'm editing is vegas 8 pro.
