;; lf-noise0 is step noise.  Generates random values at a rate given by

;; values at a rate given by the nearest integer division of the
;; sample rate by the freq argument.

;; lf-noise2 is quadratic noise.  Generates quadratically interpolated
;; random values at a rate given by the nearest integer division of
;; the sample rate by the freq argument.
