I have been thinking along these lines for some time :-)
I have some code and postprocessing running, but I am not
using the soundcard on the Linux boxes :-(
Still this is an important concern, Linux is after all the wave of
the future <flame suit on>
We need the Indefatigueable John Marcus and others in StoneSoup
to comment (you too), you are the real digitari !
Count me in, if you can use any code for TI DSP (EVM boards)
and MCSA (NIM) hardware on the ports I can send it to you.
