Abstract:
1. An apparatus for controlling a plurality of speakers grouped into at least three directional groups, each directional group having a directional group position associated with it, the apparatus comprising: a source path receiver for receiving a source path from a first directional group position to a second directional group position, and movement information for the source path; a source path parameter calculator for calculating a source path parameter for different points in time on the basis of the movement information, the source path parameter indicating a position of an audio source on the source path; a path modification command receiver for receiving a path modification command by means of which a compensation path to the third directional zone may be initiated; a storer for storing a value of the source path parameter at a location where the compensation path deviates from the source path; and a weighting factor calculator for calculating weighting factors for the speakers of the three directional groups on the basis of the source path, the stored value of the source path parameter, and information on the compensation path.
