I have been looking into designing a 12 bit A/D with a differential amplifier in front which would sample at 6, 12 or 24 Mhz delivering the raw samples to the host over USB (FX2LP chips are good at pumping USB data). In this way I have all the info I can get and then applying various algorithms to the signal is the task of the host. If the host is quick it might even be able to do processing in real-time?

There is a prudaq cape for beaglebone that gives you two coherent a/d channels Before i was locked out of my lab, I had my analog streaming usb setup from magtape hooked up to a floppy with a fluxengine to compare the output of the read channel with the analog signal out of the preamp There are a couple of pictures of it on my twitter feed, but twitter doesn't make it easy to find old tweets
