panning sound in Supercollider with a PING sensor
hello again all
i planning on panning sound in supercollider using 4 ping sensors , 1 arduino.
i want make 4 channel speaker panning machine of sorts, quadraphonic speaker arrangement.
each sensor associated 1 loudspeaker example front left , other sensors other loudspeakers.
problem not know if possible manipulate pan position 4 individual loudspeakers in supercollider, can stereo thats pretty extent of sc panning knowledge.
if has clues or info how using arduino program , supercollider please shout them out.
kind regards
jay

here interesting page on known "seeburg" quadraphonic "decoder" system, used on series of old seeburg jukeboxes (from 1970's, believe):
http://home.pacbell.net/fmillera/quad_decoder.htm
if scroll bottom area, see how speakers wired allow panning left-to-right, front-to-back, using potentiometers connected between speaker pairs vary volume.
you use similar system, , change volume mechanically coupling servos potentiometers, changing servo positions arduino based on ping sensor readings, may or may not fast enough or want.
the better approach might @ "line level" (instead of "speaker level"), , hook line level signals sound source though digital potentiometers (connected in same manner shown in diagram), , control these directly arduino (based on ping sensor readings). device sit between outputs of line-level sound source(s), , line-level inputs amplifier(s) driving speakers.
alternatively, use 4 digital potentiometers, 1 between each line-level source , amplifier, , mixing of levels , such in software (you end close same arrangement - although have better control options since speaker channel levels wouldn't coupled).
hope helps!
[edit]hmm - looking @ seeburg setup, see more of haffler mod (not quite same true quadraphonic sound); still, usage of digital potentiometers, , placing these @ line-level between sources , amps/speakers...[/edit]
