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. |
