Jock Gill points us to GNU Radio, and, in particular, to Eric Blossom’s work. (He’s been slashdotted here.) GNU Radio is a software-defined radio. Unlike regular radios that are hard-wired about what they do with the information they receive, software-defined radio can do anything it’s programmed to do… including simultaneously receiving two broadcast FM stations from a single input. (Say wha’?)

In fact, the GNU Radio — which may be your computer with a little hardware added — doesn’t have to assume the inputs are sounds at all. Although I’m only following this topic by the skin of my teeth, it seems to me that this is where the real promise lies.

(As with all GNU Brand^TM; products, GNU Radio is a public and free software project.)
