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
