(describe argument here)
In radians, -pi to pi.
In radians, -0.5pi to +0.5pi.
The speaker radius (1 places shound at the radius, <1 within the radius, >1 is outside the radius) beyond the radius, a distance scaling is applied (no filtering is done).
A control rate level input.
Chooses how the W channels is scaled. If 0, a scaler of 0.707 is used. If 1, W is varied according to the scaling of the X, Y, Z, R, S, T, U, and V channels. 1 is the default.
NOTE: Output channels are in order W,X,Y,Z, R, S, T, U, V. Because of the way the W component is scaled, it is recommended that you only decode with FMHDecode1 and it's methods.
