Abstract
Official abstract text for this publication.
A device for modifying audio signals to be output within a room is introduced. The device exhibits an input for supplying audio information and a processor unit for modifying the audio information. The device further exhibits at least two outputs for distributing respectively modified audio information. The processor unit is here adapted to modify the audio information in such a way that respective sound sources to be connected to the outputs simulate a linear sound source for outputting the audio information according to the audio signals. The linear sound source is here achieved via the coherent coupling of a plurality of point sound sources, for example loudspeakers.
