[sdiy] video signals as audio

[Todd Sines]

I am probably the wrong person to be suggesting this, but ...

after some discussion with Mr. Verbos...

would actually be interested in going the other direction; bringing  
video [analog, of course] down to the right frequency range [20hz-  
20,000hz] for some very complex harmonics.. but maybe things could  
become not so complex. A frequency shifter [Cwejman, Doepfer, etc]  
might do the trick; but are rather expensive for this sort of  
experiment; and also might not bring the frequency far enough down  
into the audio spectrum.

first thought was some simple devices, like B&W 1-chip CCD security  
cameras; maybe introduce some feedback, modify vertical  / horizontal  
hold.. ;)

but sources like Vectrexs, Telestars, Atari 2600s.. could also be  
sources of some _very_ limited signals.

curious to hear anyone else's experiments..
