The rate at which new grains are created (in Hz).
A randomness factor for window size (as a percentage of the winsize).
In radians, -pi to pi.
Percentage of deviation from the azimuth.
In radians, -0.5pi to 0.5pi.
Percentage of deviation from the eleveation.
The speaker radius. (1 places around at the radius, <1 within the radius, >1 is outside the radius.) Beyond the radius, this mostly acts as an amplitude scaler (no filtering is done).
