[Duane R Balvage]

Hello all -

I believe that Silence's description was fairly accurate, but it was 

incomplete. When you "clip" a signal, it tends to "hard limit" it

or at least compress it.

 So, after the HPF and clipping ckt. (back to back green

LED's in a feedback loop is my personal favorite - all even *and* odd

harmonics represented...), an envelope follower & VCA mix the "clipped"

signal back into the "clean" signal. That way the harmonic content 

"follows" the music volume like it should. I also have the feeling that 

the HPF loosely "tracks" the input signal's cutoff frequency - that way,

the more muffled the original, the more "enhancement" it gets....


Just my 0.02 worth, an edumucated guess at best....
