I guess it's also worth mentioning that making a decoder for the
format should be trivial, it's just raw Speex packets, packed
together as tightly as possible. I have a decoder I use for
debugging, and the source can be found here:
It outputs raw 16 bit mono files, and needs a 1.2 beta libspeex to
compile, thanks to the use of speex_bits_set_bit_buffer(), but apart
from that, it's nothing special at all.
