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.

If libsndfile has it, all the programs that use libsndfile can have
it too.

that they don't actually use an audio compression algorithm, but
rather, they use an encryption algorithm.
