A new technique uses rectangular to spherical coordinate transforms to generate an angular map, displaying auditorium seating in latitude and longitude angles as seen by the loudspeaker. Loudspeaker coverage and inverse-square losses can be instantly determined by this method. Loudspeaker radiation angular contours are presented for a number of commercial high frequency horns, as well as software for automatic computation of map point locations.
