<br>
nice to hear someone is interested :) quad lives!<br>
<br>
A scanner is one way to do it but the person I have in mind for this is more
interested in gestural motions so dual voltages for X, Y positioning is more
convenient I think. <br>
<br>
I'm happy to chat about the fundamentals of the idea, the circuit itself
is not really finished yet. <br>
<br>
What I'm playing with right now derives "quadrant" voltages from
joystick X and Y inputs to control 4 VCAs that would be for Front Right, Rear
Right, Rear Left and Front Left speakers. There is equal power breakpoint
panning between adjacent channels. The equal power law is adjustable, I'm
not sure which would be most appropriate yet (-3dB, -4.5dB, -6dB). Single-axis
panning goes down to full closed in the center and back up when going straight
across. Controlling it with a joystick, joystick straight forward sound would
come out of both front speakers at a slightly reduced amplitude, rotating
joystick to the right it would come out stronger out of only the front right
speaker, and as you continued to rotate around it would crossfade smoothly from
speaker to speaker.<br>
<br>
here is the simulation fully rotating around:<br>

<br>
and here is the simulation of single axis front-to-back motion:<br>

Serge T mentioned a CalArts paper on the subject by Darrell Johansen. I
would be interested if anyone knows where to find a copy of that for me to
read, or anything else that may be relevant.<br>
