New method for elevation panning in a loudspeaker array

The new algorithm IKA-PAN was developed to pan an audio signal between elevated loudspeakers, which means it generates different signals for the loudspeakers that the sound event appears clearly in between the elevated loudspeakers. With this algorithm the 3D-sound reproduction over a loudspeaker array is improved in either reducing the number of necessary loudspeakers for a given reproduction quality or by improving the reproduction quality keeping the number of loudspeakers, which were used without this algorithm. The new algorithm enlarges also the reproduction area.
