Ok, if there were such a project already I guess one
of you would
know. I also found nothing on the web so there probably is none. But
Perhaps something like
http://lists.linuxaudio.org/pipermail/linux-audio-dev/2009-November/024713.…
I'm going forward with it in a kind of glacial pace.
Have a look at:

A development board like the stellaris launchpad could
be a good
starting point for a prototype. It has an 80 MHz ARM CPU with floating
point, a few KB of RAM, some flash storage for code, and the ADCs
should be perfectly ok for audio. It's only 13 US$, and I have a
couple of them here.

Yes, but if you want something open source, where do you have any
suitable libs for stellaris?
There is preliminary support in http://libopencm3.org/ (under lm3s)
but I don't think it is ready for prime time.

The DSO nano quad is an open source oscilloscope with
2 analog inputs
with more bandwidth than any audio recorder would need:

...
It uses a STM32F103VCT6:

It should be doable to design something around that.
