Similar to LFNoise2 , it generates polynomially interpolated random values at a rate given by the freq argument, with 3 differences:
If you don't need very high or very low freqs, or use fixed freqs, LFNoise2 is more efficient.
| freq |
Approximate rate at which to generate random values. |
| mul |
Output will be multiplied by this value. |
| add |
This value will be added to the output. |
// try wiggling mouse quickly:// LFNoise2 overshoots when going from high to low freqs, LFDNoise changes smoothly.{ SinOsc.ar(LFNoise2.ar(MouseX.kr(0.1, 1000, 1), 200, 500), 0, 0.2) }.play{ SinOsc.ar(LFDNoise3.ar(MouseX.kr(0.1, 1000, 1), 200, 500), 0, 0.2) }.play// LFNoise quantizes time steps at high freqs, LFDNoise does not:{ LFNoise2.ar(XLine.kr(2000, 20000, 8), 0.1) }.scope;{ LFDNoise3.ar(XLine.kr(2000, 20000, 8), 0.1) }.scope;// use as frequency control({ SinOsc.ar( LFDNoise3.ar(4, 400, 450), 0, 0.2 )}.play;)
