Hi Jan, > iii) Is there an atrac3plus decoder available for GNU/Linux (for tracks > that are not encrypted). Just wanted to let you know that I talked with Benjamin and Maxim (the two guys from ffmpeg who also wrote the ATRAC1 decoder) and they told me they are already working on an implementation of ATRAC3+ for ffmpeg and therefore Linux. They have already written some code with the help of the specifications from Michael Karcher. As I said before, I provided them with your recording samples, so they should have everything you need (ok, actually the specifications are not yet complete, but it's a very good start). Adrian
