I have several MDs of assorted jazz that were downloaded from MP3.com as 128K MP3's.
I've used CoolEdit 2000 to decompress and play them via S/PDIF (TOSlink) to the MDS-PC
recorder. I've noticed very few artifacts that I can attribute to the MDs ATRAC
encoding. The biggest problem with

And may in fact be undetectable, depending on the MP3 encoder and decoder

You aren't recompressing compressed data; you are compressing the
decompressed output of a previous compression. The various codecs have
overlap in what they consider expendable; they are not orthogonal to one
another.
David, I'm not sure exactly

The point that David, Ratman and others have tried to make to you is that yes
this is some additional compression when you record MP3 files on to MD, but the
