The mic. has a very 
clean high dynamic range, it could be used by the FBI!  Be looking for a
review from Peggy Herrington. What I have done is modify the input such
that the mouse simulates the sound input. You can think of this program,
"Viz", as  a real time "live art machine", to operate, you hit the keys 
and move the mouse,  great for kids! Actually, there are many animation
controls, every single Vanilla Key is used, both upper and lower case.
This program contains a browser I/O window, allowing you to search 
disks, view lo-res IFF files, and use them as backdrops. The letter keys
are what we call "modes", each being a  kinetic  perception of sound.
You are probably running the program and pressing keys already ... 

 Go to the  Animation-Disk I/O window click: df1: -  Visuals - IFF_1
LOAD_IFF  wait... VIEW - VIEW - QUIT... now you are back out the window.
Now press the `  key (below the ESC key). You now are in backdrop
animation, press some letter modes, now press the = key,  now the \ key.

  Some modes, ( w, W, f, F, u, U ) have a whole range of V numbers:
  1   2   Fast Tweek        3  Stop
  0   .   Slow Tweek        - display V      --- Master Reset

  Try this: press the f key (flame mode), press the - key three times to
reset the V number, press the 1 key, the - key, and get ready to press
the 3 key... You should see a number down at the right corner counting
negatively, when that number gets near -1300 press the 3, now fine tweek
the number to -1296 using the 0 and . keys, press 3 to stop and - to 
remove V number display.  While doing this, move the mouse.
