Re: equalizer with feedback effect

If I only use "clip" once then the code works as-expected (symmetrically) on stereo ...
It's an approximation of the changing acoustic-feedback if the guitarist was moving-about near the loudspeaker
Code: Select all
;version 4
(setq A1 (hzosc 0.090909))
(setq A2 (hzosc 0.052631))
(setq A3 (hzosc 0.034482))
(setq A4 (hzosc 0.024390))
(setq P 0.05) ; Recommend P<0.08
(clip (sim (mult A1 -0.5) (mult A2 -0.5) (mult A3 -0.5) (mult A4 -0.5)
(mult (sum 0.5 (feedback-delay *track* 0.00502512 (* 11 P))) A1)
(mult (sum 0.5 (feedback-delay *track* 0.01492537 (* 3 P))) A2)
(mult (sum 0.5 (feedback-delay *track* 0.02325581 (* 2 P))) A3)
(mult (sum 0.5 (feedback-delay *track* 0.03255813 (* 9 P))) A4)).5)
