I've got some time for hacking on this today, and I just pushed an update to my wip repo (http://www.southpole.se/~nisse/libav.git, branch xll).
I fixed parsing of the sample data which I had some trouble with a few weeks ago. It turned out it was the hybrid rice flag that wasn't handled correctly. And then I have a made first attempt at implementing the "inverse adaptive prediction" and "inverse channel correlation". Next steps: 1. Do the msb/lsb reassembly. 2. Figure out how to actually generate any output to the codec user, and d any needed channel permutation. After that, it should be possible to get some audio out, and try to debug this thing. Not yet at all implemented: Fixed prediction (that wasn't used in my primary test input), and the mode of operation where the xll sample data is added as a correction term to the "core" audio data.
