摘要： In order to control a wave field synthesis rendering device arranged in a wave field synthesis system, a scene description is used (1) in which an absolute position or an absolute time is not specified for a source but a time span or location span within which the audio object can vary. In addition, a monitor (2) is provided which monitors a capacity utilization situation of the wave field synthesis system. Finally, an audio object manipulator (3) varies the actual starting point of the audio object, which starting point is to be taken into consideration by the wave field synthesis rendering device, or the actual position of the audio object within the time span or the location span in order to avoid capacity bottlenecks on the transmission lines or in the rendering device.

摘要： The invention relates to a method for producing a low-frequency channel for a low-frequency speaker which is disposed in a predetermined low-frequency speaker position. According to said method, a plurality of audioobjects is provided (900), and an object position and an object description is associated with every audioobject. A calculation (906) of an audioobject calibration value for every audioobject is carried out in accordance with the object description so that an actual amplitude status at a reference playback position at least approximates a desired amplitude status. Every object signal is scaled with an associated audioobject scaling value (910) and the scaled object signals are summed up (914). The sum signal thereby obtained is used to derive a low-frequency channel for the low-frequency speaker and the corresponding low-frequency speaker is provided (918). The scaling of the individual object signals of the audioobjects renders the method independent of an actual situation of a multichannel projection system with respect to the number and density of the speakers and with respect to the size of the actually present projection zone.

摘要： The invention relates to a device for delivering data for electromagnetic field synthesis treatment in an electromagnetic field synthesis system containing a plurality of renderer modules, at least one loudspeaker being associated with each renderer module, and the loudspeakers assigned to the renderer modules being applicable to different positions in a reproduction region. The inventive device comprises a system (22) for delivering a plurality of audio files, a virtual source being associated with an audio file on a source position. The inventive device also comprises a data output device (24) for delivering the audio files to a renderer with which an active loudspeaker is associated, while the data output device (24) is also embodied in such a way as to not deliver the audio files to a renderer, when all the loudspeakers associated with the renderer do not need to be active for the reproduction of the source. In this way, unnecessary data transmissions in the electromagnetic field synthesis system are avoided, the maximum renderer capacity being simultaneously exploited in a multi-renderer system in an optimum manner.
