Description::

Generates linearly interpolated random values at a rate given by the
nearest integer division of the sample rate by the
code::freq::  argument.


classmethods::

method::ar, kr

argument::freq
Approximate rate at which to generate random values.

argument::mul
Output will be multiplied by this value.

argument::add
This value will be added to the output.

Examples::

code::
{ LFNoise1.ar(1000, 0.25) }.play;

// modulate frequency

{ LFNoise1.ar(XLine.kr(1000, 10000, 10), 0.25) }.play;

// as frequency modulator
(
{ SinOsc.ar(
		LFNoise1.ar(4, 400, 450),
		0, 0.2
	)
}.play;
)

// freq is the rate of starting points
{ var freq = 1000; [LFNoise1.ar(freq), Impulse.ar(freq)] }.plot
