In a reproduction area where there are at least three directional groups, each of which has speakers, triggering of the speakers is achieved in that a source path from a first directional group position to a second directional group position is initially obtained along with movement information for the source path. Subsequently, a source path parameter is calculated 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. In addition, a path modification command is received to define a compensation path to the third directional zone, a value of the source path parameter further being stored at a location where the compensation path deviates from the source path, and being used, along with a compensation parameter, for calculating weighting factors for the speakers of the three directional groups.

Apparatus and method for controlling a plurality of speakers by means of a graphical user interface

In a reproduction environment, speakers are grouped in directional groups, wherein the directional groups overlap with respect to the associated speakers so that speakers are present which have a speaker parameter having different values for the first directional group and the second directional group. A controller for controlling a plurality of speakers has a provider for providing a source position of an audio source, wherein the source position is located between the first directional group position and the second directional group position. The apparatus further has a calculator for calculating a speaker signal for the at least one speaker, based on the first parameter value for the speaker parameter and based on the second parameter value for the speaker parameter.
