;; (crackle rate chaosParam)

;; A noise generator based on a chaotic function.  The parameter of
;; the chaotic function has useful values from just below 1.0 to just
;; above 2.0. Towards 2.0 the sound crackles.

;; The equation implemented is: y0 = fabs(y1 * param - y2 - 0.05f)

(audition (out 0 (mul (crackle ar 1.95) 0.5)))

;; Modulate chaos parameter
