Patent ID: 8755922

Claim:
An apparatus for controlling a wave field synthesis renderer with audio objects, so that the wave field synthesis renderer generates, from the audio objects, synthesis signals reproducible by a plurality of loudspeakers attachable in a reproduction room, comprising: a provider arranged to provide a scene description, the scene description defining a temporal sequence of audio objects in an audio scene, and wherein each audio object of the temporal sequence of audio objects in the audio scene includes information on a source position of a virtual source as well as an audio file for the virtual source or reference information referring to the audio file for the virtual source; and a processor arranged to process the audio objects, in order to generate a single serial output data stream, which is to be fed to the wave field synthesis renderer, the single serial output data stream comprising both the audio file of the audio object and, in association with the audio file, information on the position of the virtual source of the audio object; wherein the processor is arranged to generate the single serial output data stream so that, for each audio object of the temporal sequence of audio objects in the scene, a header, in which the position information for the virtual source for each object is included, is followed by the audio file for the virtual source for each object or follows the audio file for the virtual source for each object, so that the wave field synthesis renderer is capable of determining, based on the temporal position of the header with reference to the audio file, that the audio file is to be rendered with the position information in the header; and the apparatus for controlling a wave field synthesis renderer comprises a hardware device.
