Patent ID: 7668611

Claim:
An apparatus for controlling a wave field synthesis renderer arranged in a wave field synthesis system, wherein the wave field synthesis renderer is formed to generate, from audio objects, wherein an audio file for a virtual source arranged at a source position is associated with an audio object, synthesis signals for a plurality of loudspeakers coupled to the wave field synthesis renderer, comprising: a provider for providing a scene description, wherein the scene description sets a temporal sequence of audio objects, wherein an audio object defines a temporal start or a temporal end for a virtual source associated with the audio object, wherein the audio object for the virtual source comprises a time span in which the start or the end of the audio object must exist, or wherein the audio object comprises a location span in which a position of the virtual source must exist; a monitor for monitoring a utilization situation of the wave field synthesis system; and an audio object manipulator for varying an actual starting point or an actual end point of the audio object to be considered by the wave field synthesis renderer within the time span or an actual position of the virtual source within the location span, depending on a utilization situation of the wave field synthesis system.
