How to sweep the phase with AppleScript

this AppleScript script will repeat -180 to 180 degree phase sweep three times. set lp to -180 -- the lowest phase in degree set hp to 180 -- the highest phase in degree set rv to 0 -- set to 1 for reverse (hp to lp) set rp to 3 -- repeat 3 times if hp is less than lp then set tmp to lp set lp to hp...
