>Probably 95% of what people do with EEG biofeedback at present is at
freqs above 5Hz, although it would be nice if one could just stretch it
down to 4Hz and thereby cover the traditonal Theta band.<<
That's incorrect. Most people are working with Theta inhibition if they are
working with ADD or squash protocols (and the slower wave delta with the
squash protocols).
Theta filters usually have a gradual cut-off. And some people say theta
starts at 3 Hz.
But irregardless, I'd be surprised if our intrepid programmers can't find a
way to get around the low frequency limitations. I think it's a great idea
to make this technology as affordable as possible to as many people as
possible.
>>And now another thought: It seems to me that we are not only on the
verge of providing cheap EEG biofeedback devices, but also have the
essential features in hand to produce cheap EMG, EKG (as in heart rate
variability), electrodermal, and maybe some other types of biofeedback as
well. Putting this entire range of equipment out into
public access could revolutionize the capacity of humans to self-regulate.

Absolutely!! And actually, if you are creating a piece of freeware that
taps the capabilities of the soundcard, you may find there are a lot of
other applications as well.
