If I understand the full ramifications of what you've just said, I think
you've just answered my question, but because I'm curious, I'll ask anyway:
Can the different ATRAC compression algorithms result in data loss that is
not directly related to ATRAC? For example, is it possible to get more
definition in a recording with a company's v1.0 compression/encoding engine
(algorithm) than with the same company's later (and presumably better) v8.0
compression engine?
