Like LFNoise1, it generates linearly interpolated random values at a rate given by the freq argument, with two differences:
If you don't need very high or very low freqs, or use fixed freqs, LFNoise1 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. |
