Decoding of mono AT3+ using SonicStage

[Hykem]

Well, I've collected enough information on the ATRAC3+ codec from reversing the codec and atrac3plus libs in order to verify most of the conclusions on the ATRAC3+ Multimedia Wiki page, so, with some more research, it may be possible to create our own transcoder.
But, of course, this will be a much harder solution...

Isn't the Atrac3+ decoding done in hardware on a PSP???

Yes. What I meant is that you can analyze the way the PSP interacts with it's ME chip by studying it's libs and then verify the results against the hardware research being done by FFMPEG.
