lfNoise1 rate freq
Ramp noise. Generates linearly interpolated random values at a
rate given by the nearest integer division of the sample rate by
the freq argument.
freq - approximate rate at which to generate random values.
> audition . (out 0) . (* 0.05) =<< lfNoise1 AR 1000
Modulate frequency.

> n <- lfNoise1 AR f
> audition (out 0 (n * 0.05))
Use as frequency control.
