Audiowiedergabesystem und Verfahren zum Wiedergeben eines Audiosignals

WO2004047485 A UPAB: 20040702 NOVELTY - A central wave field synthesis module (10), determines audio channel information, to match each audio channel virtual position with a loudspeaker position. The virtual position is dependent on the audio source position associated with the audio track, such that audio channel information exists for each channel, from each virtual position to each loudspeaker, in order to calculate synthesis signals from the virtual position for the loudspeaker (24), in order to supply one or more synthesis signals to each loudspeaker. DETAILED DESCRIPTION - These signals are reproducible by the relevant loudspeaker. Additional channel information is supplied for one or more synthesis signals. The method is further elaborated on the basis of the foregoing principles. An INDEPENDENT CLAIM is included for a corresponding method and computer program product. USE - An audio reproduction system playing tracks into specific, fixed-position speakers. A wide range of auditoria is targeted for commercial ends, from the small room to a large hall, including cinemas. ADVANTAGE - The audio reproduction concept is designed for greater acceptance in the market place. This derives from its scalability. This is related in turn to computing power and price. A system for a small reproduction room or hall costs less than one for larger auditoria such as cinemas
