摘要： For controlling a wave field synthesis renderer arranged in a wave field synthesis system, a scene description, in which not an absolute position or an absolute time instant, but a time span or location span within which the audio object may vary is indicated for a source, is used. Furthermore, there is provided a monitor, which monitors a utilization situation of the wave field synthesis system. An audio object manipulator finally varies the starting point of the audio object to be considered by the wave field synthesis renderer or the actual position of the audio object within the time span and/or location span, in order to avoid capacity bottlenecks on the transmission lines or in the renderer.

摘要： An apparatus for providing data for wave field synthesis rendering in a wave field synthesis system with plurality of renderer modules, at least one loudspeaker being associated with each renderer module, and the loudspeakers associated with the renderer modules being attachable at different positions in a reproduction room, includes a provider for providing a plurality of audio files, wherein a virtual source at a source position is associated with an audio file, and a data output for providing the audio file to a renderer with which an active loudspeaker is associated, with the data output further formed to not provide the audio file to a renderer if all loudspeakers associated with the renderer are not to be active for the reproduction of the source. Thus, unnecessary data transmissions in the wave field synthesis system are avoided, while making optimum use of the renderer maximum capacity in a multi-renderer system.

摘要： An apparatus for controlling a wave field synthesis renderer with audio objects includes a provider for providing a scene description, wherein the scene description defines a temporal sequence of audio objects in an audio scene and further includes information on the source position of a virtual source as well as on a start or an end of the virtual source. Furthermore, the audio object includes at least a reference to an audio file associated with the virtual source. The audio objects are processed by a processor, in order to generate a single output data stream for each renderer module, wherein both information on the position of the virtual source and the audio file itself are included in mutual association in this output data stream. With this, high portability on the one hand and high quality due to secure data consistency on the other hand are achieved.

摘要： For simulating a wave field synthesis system, an audio scene description defining a temporal sequence of audio objects is provided, an audio object having an audio file for a virtual source or a reference to the audio file and information on a source position of the virtual source. Furthermore, an output condition the wave field synthesis system is to satisfy is given. Furthermore, a simulator for simulating the behavior of the wave field synthesis system for the audio scene description, using the audio data and the source positions as well as information on the wave field synthesis system, is provided. Finally a checker performs a check to determine if the simulated behavior of the wave field synthesis system satisfies the output condition. This achieves more flexible audio scene description creation as well as flexible portability of an audio scene description developed for one system to another wave field synthesis system.

摘要： For generating a low-frequency channel for a low-frequency loudspeaker arranged at a predetermined low-frequency loudspeaker position, a plurality of audio objects are initially provided, each audio object having an object position and an object description associated with it. Hereafter, a calculation of an audio object scaling value is performed for each audio object on the basis of the object description, so that an actual amplitude state at least comes close to a target amplitude state at a reference playback position. Thereafter, each object signal is scaled with an associated audio object scaling value so as to then sum the scaled object signals. From the composite signal obtained there, a low-frequency channel is subsequently derived for the low-frequency loudspeaker, and is provided to the respective low-frequency loudspeaker. Due to the scaling of the individual object signals of the audio objects, this approach is independent of an actual situation of a multichannel playback system with regard to the number and density of the loudspeakers as well as with regard to the size of the presentation area actually present.

摘要： An audio reproduction system is divided into a central wave-field synthesis module and a plurality of loudspeaker modules disposed in a distributed way, wherein synthesis signals for the individual loudspeakers as well as corresponding channel information associated to the synthesis signals are calculated in the central wave-field synthesis module. The synthesis signals for a loudspeaker as well as associated channel information will then be transmitted to respective loudspeaker modules via a transmission path, wherein every loudspeaker module obtains the synthesis signals and associated channel information intended for the loudspeaker associated to the loudspeaker module. A distributed audio rendering and digital/analog converting takes place in the loudspeaker module to generate the actually analog loudspeaker signals in a distributed way in spatial proximity to every loudspeaker. The division into a central wave-field synthesis module and the plurality of distributed loudspeaker modules allows that audio reproduction systems that are scalable with regard to the price can be generated in order to offer systems of different size scalable in price particularly for cinema reproduction rooms varying strongly in size.
