;; lfd-noise0: Dynamic step noise. Like lf-noise0, it generates random

|
|
;; no time quantization, and fast recovery from low freq values.

;; lfd-noise1: Dynamic ramp noise. Like lf-noise1, it generates linearly
|
|
;; interpolated random values at a rate given by the freq argument,

|
;; with two differences: no time quantization, and fast recovery from
|
|
;; low freq values.

;; lfd-noise3: Dynamic cubic noise. Like Lf-Noise3, it generates
|

;; linearly interpolated random values at a rate given by the freq

;; recovery from low freq values.

;; (lf-noise0,1,3 quantize to the nearest integer division of the
|
|
;; samplerate, and they poll the freq argument only when scheduled,
|

;; and thus seem to hang when freqs get very low).

|
;; If you don't need very high or very low freqs, or use fixed freqs,

;; Try wiggling mouse quickly; Lf-Noise frequently seems stuck,
|
|
;; LFDNoise changes smoothly.
