APPARATUS AND METHOD FOR CONTROLLING A PLURALITY OF LOUDSPEAKERS BY MEANS OF A GRAPHIC USER INTERFACE

摘要

The aim of the invention is to trigger loudspeakers in a reproduction zone in which at least three directional groups are provided, each of which comprises loudspeakers. Said aim is achieved by first obtaining a source path from a first directional group position to a second directional group position along with a piece of movement information for the source path (800). A source path parameter is then calculated for different points in time based on the movement information, said source path parameter indicating a position of an audio source along the source path. Furthermore, a path modification command is received (804) in order to define a compensation path to the third directional zone while a value of the source path parameter at a point where the compensation path deviates from the source path is stored and is used together with a compensation parameter to calculate (810) weighting factors for the loudspeakers of the three directional groups.
