/* The target direction is expected to be in spherical point form:
* a,e,r
*
* Where 'a is the azimuth of the first mic channel, 'e' its elevation,
* and 'r' the radius.
* Where 'a' is the azimuth of the target point relative to the center of

* 0 radians azimuth is to the right of the array, and positive angles
* move in a counter-clockwise direction.
