        Bravo Brad!  Thanks for all the work you're putting into this!  I 
have only one comment:

> 2.0 The Leslie Speaker

        In addition to the AM, FM, and reflected sound, there is also a 
timbral shift with rotation.  The treble content of the speaker output heard 
by the listener increases as the source rotates toward the listener and 
decreases as the source rotates away due to the directional characteristics 
of sound waves.  Higher frequency waves (shorter) are more easily trapped 
than lower frequecy waves (longer) so the when speaker is pointing away from 
the listener there are fewer high frequencies reaching the listener.
