I had intended to do it but i was surprised by the limitations.

It only works on linux, they pulled support for the important part on mac.
and it doesnt work on win32
The sample rate can never be 8k (its like forced to 48k or something) so we
have to always resample.


I helped out with the development of that
we actually already have the equivalent (mod_soundtouch)

Jack has nothing to do with that, jack is for streaming audio from your
soundcard on one box to another as if the other box was the one with the
soundcard so you could say play music on hold pumped from your itunes on
your desktop as a jack://my_box type stream.

If it weren't for all the limtations I would have done it already.
