That's great news! For some reason I was thinking that most LAD stuff
works in 44.1/16 which really isn't the best for professional audio. I
only dither down when mastering to a CD.
Hmm.. ok. Does anyone go up to 96Khz sampling?
Just trying to get a feel what people see as acceptable etc.
-Lea.
PS: I never use 96Khz but I'm sure there are plenty who would want to
use LAD technology for DVD authoring in the future.
