I have my doubts that ATRAC would be contributing much. The sound was
already ruined before it got there, so who cares. It's not the job of
ATRAC to clean up the mess that occurred before it.
My own experience is that ATRAC could record this accurately. At least
the newer versions. But, I for one have no need to experiment on that. I
work to not feed it this sort of stuff.
The real culprit, and I think what Rich was getting at is overdriving in
pre and A/D. He is right, this is common. It will be just as common in
the new solid state digitals. It's a matter of teaching folks to handle
digital recording. There's still a lot of recording advice floating
around that's straight from analog recording and ruins digital
recordings. We need to root that out.
