    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 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 generating, storing or editing an audio representation of an audio scene includes audio processing means for generating a plurality of speaker signals from a plurality of input channels as well as means for providing an object-oriented description of the audio scene, wherein the object-oriented description of the audio scene includes a plurality of audio objects, wherein an audio object is associated with an audio signal, a starting time instant and an end time instant. The apparatus for generating further distinguishes itself by mapping means for mapping the object-oriented description of the audio scene to the plurality of input channels, wherein an assignment of temporally overlapping audio objects to parallel input channels is performed by the mapping means, whereas temporally sequential audio objects are associated with the same channel. With this, an object-oriented representation is transferred into a channel-oriented representation, whereby on the object-oriented side the optimal representation of a scene may be used, whereas on channel-oriented side the channel-oriented concept users are used to may be maintained.

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.
