9 Like link::Classes/LFNoise1:: , it generates linearly interpolated
10 random values at a rate given by the code::freq::
11 argument, with two differences:
13 ## no time quantization
14 ## fast recovery from low freq values footnote::
15 link::Classes/LFNoise0:: , link::Classes/LFNoise1:: and
16 link::Classes/LFNoise2:: quantize to the nearest integer division
17 of the samplerate, and they poll the code::freq::
18 argument only when scheduled; thus they often seem to hang
19 when freqs get very low.
23 If you don't need very high or very low freqs, or use fixed freqs,
24 link::Classes/LFNoise1:: is more efficient.
32 Approximate rate at which to generate random values.
35 Output will be multiplied by this value.
38 This value will be added to the output.
43 // try wiggling mouse quickly;
44 // LFNoise frequently seems stuck, LFDNoise changes smoothly.
