Hi Peter,

I've mentioned before about doing a talk on Jack, and I'm still
interested in doing that - just it kinda got a little forgotten about.

Have to say I don't know anything about Gstreamer or Pulse so no
mention by me of them (except to disable Pulse if you're trying to use
Jack).

With Jack I can show you recording and analysis. I don't have
experience with streaming or really know much about it. Can you
explain more about this part of what you want to do? It sounds like a
3 stage process - record, stream, analyse - rather than an
simultaneous in-line process.

With Jack you can simultaneously record and analyse. What Jack has
that others don't is flexibility and routing between applications.

I can also give some basic guidance on setting up a system for use with Jack.

It wouldn't be a long talk, nor would it be a jam session, nor would a
20K rig be required ;-)


Cheers,
James.
