That looks like a good start.  The example files gives loads of
example combinations of carriers and beat frequencies, as do the
measured Monroe Institute tone-sets (also available on my web-site).

The truth is, though, we're all experimenting (even the Monroe
Institute, although they've had more practice than the rest of us).

According to the M.I. there is a limited range of carrier frequencies
for which binaural beats are generated in the brain.  The upper limit
is around 1000-1500Hz.  Carriers above this are no good.  I've used
carriers as low as 60Hz.  One Monroe Institute patent mentions an
"Oersted curve".  The way they talk about it indicates that most
probably this curve plots the effectiveness of carrier frequency
against frequency, and they mention that this peaks at around 275Hz.

Regarding the beat frequencies, I've been experimenting with what I
call sub-delta - beats below 1Hz.  Something critical appears to
happen around 0.9Hz - in my limited experiments some time ago I found
that working downwards little by little, at this frequency I started
to wake up again.

I have a nightly sequence that I run from time to time which
stimulates frequencies randomly in this sub-delta region (along with
some other frequencies), 5 mins on, 5 mins off all night.  Sleeping
does seem to be more efficient this way.

I'll be including this sequence in the new release which shouldn't be
far off now - check out the announcement posted to the list
separately.
