lfNoise0 rate freq

Step noise.  Generates random values at a rate given by the nearest
integer division of the sample rate by the freq argument.

> audition . (out 0) . (* 0.05) =<< lfNoise0 AR 1000

Modulate frequency.

> let f = xLine KR 1000 10000 10 RemoveSynth
> in do { n <- lfNoise0 AR f
>       ; audition (out 0 (n * 0.05)) }

Use as frequency control.

> f <- lfNoise0 KR 4
> audition (out 0 (sinOsc AR (f * 400 + 450) 0 * 0.1))
