A while ago we asked Ardour team if they wanted some

reverse-engineered. Paul named a couple of such file formats,
including REX2 audio loops [2].
I attempted reverse engineering this file format for includsion
in libsndfile a number of years ago but made little progress beyond
reading the actual chunck data. The results of that work is in
the src/rx2.c of the libsndfile tarball. It can be enabled by
configuring libsndfile with --enable-experimental.
And since we do it not just for fun, but for actual
results, we'd be
glad if developers of other applications (FreeCycle and Smasher are
the first I can think of) implemented support for REX2.
If libsndfile has it, all the programs that use libsndfile can have
it too.
Coincidentally we are also interested in people who
are good at audio
compression algorithms. *cough* Monty *cough* :)
From my previous work on this file format, I came to
the conclusion
that they don't actually use an audio compression algorithm, but
rather, they use an encryption algorithm.
