Speaker Properties.
The origin for azimuth is right (as by math conventions dealing with radians).
The elevation origin is also right, visualizing a rotation of a circle across the
-pi/pi axis of the horizontal circle. Thus, an elevation of -pi/2 corresponds
to bottom, and a speaker standing on the left, and 'beaming' upwards would have
an azimuth of -pi, and an elevation of pi/2.
For user interface representation, grads are more likely to be used, and the
origins will obviously 'shift' accordingly.
