Abstract
Zum Steuern einer in einem Wellenfeldsynthese-System angeordneten Wellenfeldsynthese-Rendering-Einrichtung wird eine Szenenbeschreibung verwendet, in der fuer eine Quelle nicht eine absolute Position oder ein absoluter Zeitpunkt angegeben ist, sondern eine Zeitspanne oder Ortsspanne, innerhalb der das Audioobjekt variieren kann. Ferner ist ein Ueberwachungsmonitor vorgesehen, der eine Auslastungssituation des Wellenfeldsynthese-Systems ueberwacht. Ein Audioobjektmanipulator schliesslich variiert den von der Wellenfeldsynthese-Rendering-Einrichtung zu beachtenden tatsaechlichen Startpunkt des Audioobjekts oder die tatsaechliche Position des Audioobjekts innerhalb der Zeitspanne bzw. der Ortsspanne, um Kapazitaetsengpaesse auf den Uebertragungsleitungen oder in der Rendering-Einrichtung zu vermeiden.

 

DE 102005008333 A1 UPAB: 20061208 NOVELTY - The device has a control monitor (2) to monitor an extent of utilization situation of a wave field synthesis system with a wave field synthesis rendering device. An audio object manipulation device (3) varies a start point/end point of an audio object within a time period or an actual position of a virtual source within a local span, by the rendering device, depending on the situation of the wave field synthesis system. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method of controlling a wave field synthesis rendering device arranged in a wave field synthesis system (2) a computer program with a program code for executing a method of controlling a wave field synthesis rendering device arranged in a wave field synthesis system. USE - Used in entertainment electronics such as multimedia systems, for controlling a wave field synthesis rendering device arranged in a wave field synthesis system, where the rendering device is designed to produce synthesis signals from audio object comprising an audio file for a number of loudspeakers within a loudspeaker array. ADVANTAGE - The audio object manipulation device varies a start point/end point of an audio object within a time period or an actual position of a virtual source within a local span, by the rendering device, depending on the extent of utilization situation of the wave field synthesis system, thereby avoiding capacity constraint on the transmission lines or in the rendering device. The control device hence reduces the quality break-down of the wave field synthesis system and enables the wave field synthesis system to achieve a high flexibility of application at the same time. The control device controls the wave field synthesis rendering device arranged in a wave field synthesis system in a flexible manner at low cost.
