wtf is atrac type R ?
Am I correct in thinking that it is only found in decks?
Thanks

Sony doesn't say, and now it is impossible to find out unless Sony tells us.
The reason for this is that Sony now uses different ATRAC DSP chips for the
portables and the decks.
We can safely assume, however, that it is not type-R, because it would have
been an important advantage over other por

Atrac version only affects the way it is recorded in the first place,
not how it is played back. Just get the one you want and it will be
compatible.

Hi there,
The DSP chips on recent Sony portables (i.e. from the R90 generation
onwards) are used in portables only and not home decks. So we can no longer
find out the ATRAC version by a "matching" method.
The only way to find out is to ask Sony, assuming that they don't mind
telling you.

Hi,
I am extremely interested in ATRAC, could you point me to the right
direction with a few links to various sites that's got the algorithm? where
did you get yours from? Any info would be great. I am hoping to gather more
info about it any maybe use it to do my dissertation next year.
Cheers,
I think everybody here would be glad to erceive a copy of this
software that you have. It sounds like just the thing that all of us
have been waiting for. Please let us (me) know how we can get this
for ourselves.
Thanks
