I haven't done anything with the audio device, but shouldn't it be possible
for a new/possibly massively changed audio device to do digital reverb within
the machine, instead of buying an add-on?  Maybe not quite as great in sound
quality, but it could provide some reverb and maybe stereo imaging effects.
(speculation)

I'm thinking along the lines of audio.device remembering the previous N samples
sent to the D/A (somehow in sync with the DMA) and altering the samples yet
to some to get the reverb effect.  Maybe 8 bits would be too much quantization
error in the reverb components.  Anyone care to comment? experiment?
