Abstract (en)
[origin: WO2009056858A2] There is disclosed a method and apparatus to assist in setting up an array-type Sound Projector. A sound beam is swept around the room and the magnitude of maximum correlation between the emitted test signal and a received signal at the listening position, along with the time of said maximum correlation, are recorded. Rules are then applied to determine the optimum position of the sound channels during playback. Sound beams having a wide angle and shorter path length are preferred for the left and right sound channels, whereas sound beams having smaller angles and longer path lengths are preferred for the surround sound channels.
