Patent ID: 7706544

Claim:
An audio reproduction system for a reproduction room, in which a plurality of loudspeakers are disposed at a plurality of defined loudspeaker positions, wherein an audio signal with a plurality of audio tracks is used, wherein a different virtual audio source position is associated to each audio track of the plurality of audio tracks, the audio reproduction system comprising: a central wave-field synthesis module, formed to determine, for each virtual audio source position of the plurality of audio tracks, audio channel information for an audio channel from the virtual audio source position to a defined loudspeaker position of the plurality of defined loudspeaker positions, wherein the audio channel information is obtained for each channel from each virtual audio source position of the plurality of audio tracks to each loudspeaker of the plurality of loudspeakers, calculate synthesis signals for the plurality of loudspeakers using amplitude scaling and time delaying the plurality of audio tracks, wherein the synthesis signals for the plurality of loudspeakers for each audio track of the plurality of audio tracks associated with the different virtual audio source positions are obtained, and supply the synthesis signals calculated for the plurality of audio tracks associated with the different virtual audio source positions and the audio channel information for each virtual audio source position of the plurality of audio tracks to each loudspeaker of the plurality of; a plurality of loudspeaker modules, wherein each loudspeaker module of the plurality of loudspeaker modules being associated to at least one loudspeaker of the plurality of loudspeakers, and wherein each loudspeaker module of the plurality of loudspeaker modules comprises: a receiver for receiving the synthesis signals for the respective at least one loudspeaker for each virtual audio source position of the plurality of audio tracks and the audio channel information for each virtual audio source position to the respective at least one loudspeaker; a renderer for calculating a reproduction signal for the respective at least one loudspeaker by using the synthesis signals for each virtual audio source position of the plurality of audio tracks and the audio channel information for each virtual audio source position to the respective at least one loudspeaker; and a signal processor for generating an analog loudspeaker signal from the reproduction signal for the respective at least one loudspeaker; and a plurality of transmission paths from the central wave-field synthesis module to each loudspeaker module of the plurality of loudspeaker modules, wherein each transmission path is coupled to the central wave-field synthesis module on the one hand and to an individual loudspeaker module of the plurality of loudspeaker modules on the other hand.
