From Bluetooth audio or GSM you'd probably be able to connect direct using the same arrangement. Also I'd have thought you could decode a sine wave or silence using just a diode + capacitor?
You could do some kind of decoding in software, but you'd almost certainly want that to happen in C code rather than JS... It would also pretty much destroy any hopes you might have for power efficiency :)
