Or maybe I understand how others will read it. Posts into the internet
are near immortal. I look at these statements and ask how all possible
readers will interpret what's said. What was said contained a error that
leads to false conclusions.
I'm hiding from nothing, I use ATRAC, I understand what it does and does
not do. I've put considerable study into what's going on and what comes
out. You are hiding behind "lossy compression" without understanding
what it is in this case.
DAT is lossy compression, hard disk digital is lossy compression, every
single digital sampling method for sound is lossy. The question is not
is it lossy, they all are. The question is what does that mean. Saying
it's lossy is just the beginning, not the end of the discussion.
Maybe the reason you preach this gospel of lossy compression is due to
your wilful mis-reading of other's comments. From where I stand that
makes as much sense.
