Patent number: 8755922Abstract: 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.Type: GrantFiled: February 24, 2011Date of Patent: June 17, 2014Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Katrin Reichelt, Gabriel Gatzsche, Sandra Brix

Patent number: 8189824Abstract: In a reproduction area where there are at least three directional groups, each of which has speakers, triggering of the speakers is achieved in that a source path from a first directional group position to a second directional group position is initially obtained along with movement information for the source path. Subsequently, a source path parameter is calculated for different points in time on the basis of the movement information, the source path parameter indicating a position of an audio source on the source path. In addition, a path modification command is received to define a compensation path to the third directional zone, a value of the source path parameter further being stored at a location where the compensation path deviates from the source path, and being used, along with a compensation parameter, for calculating weighting factors for the speakers of the three directional groups.Type: GrantFiled: July 5, 2006Date of Patent: May 29, 2012Assignee: Fraunhofer-Gesellschaft zur Foerderung der Angewandten Forschung e.V.Inventors: Michael Strauss, Michael Beckinger, Thomas Roeder, Frank Melchior, Gabriel Gatzsche, Katrin Reichelt, Joachim Deguara, Martin Dausel, Renè Rodigast

Patent number: 8160280Abstract: In a reproduction environment, speakers are grouped in directional groups, wherein the directional groups overlap with respect to the associated speakers so that speakers are present which have a speaker parameter having different values for the first directional group and the second directional group. A controller for controlling a plurality of speakers has a provider for providing a source position of an audio source, wherein the source position is located between the first directional group position and the second directional group position. The apparatus further has a calculator for calculating a speaker signal for the at least one speaker, based on the first parameter value for the speaker parameter and based on the second parameter value for the speaker parameter.Type: GrantFiled: July 5, 2006Date of Patent: April 17, 2012Assignee: Fraunhofer-Gesellschaft zur Foerderung der Angewandten Forschung e.V.Inventors: Michael Strauss, Michael Beckinger, Thomas Roeder, Frank Melchior, Gabriel Gatzsche, Katrin Reichelt, Joachim Deguara, Martin Dausel, Renè Rodigast

Patent number: 7962231Abstract: 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.Type: GrantFiled: August 17, 2007Date of Patent: June 14, 2011Assignees: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V., Tu IlmenauInventors: Katrin Reichelt, Gabriel Gatzsche, Thomas Heimrich, Kai-Uwe Sattler, Sandra Brix

Patent number: 7813826Abstract: Audio files for an audio piece are stored in cross-scene optimized manner, so that when reading out audio files for a scene entailing high utilization of a wave field synthesis system, very short memory access times are achieved, whereas for scenes not entailing such a high utilization of the wave field synthesis system, longer memory access times in turn are accepted.Type: GrantFiled: August 10, 2007Date of Patent: October 12, 2010Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Katrin Reichelt, Gabriel Gatzsche, Sandra Brix

Patent number: 7809453Abstract: 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.Type: GrantFiled: August 10, 2007Date of Patent: October 5, 2010Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Katrin Reichelt, Gabriel Gatzsche, Frank Melchior, Sandra Brix

Patent number: 7680288Abstract: 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.Type: GrantFiled: August 4, 2004Date of Patent: March 16, 2010Assignee: Fraunhofer-Gesellschaft zur Foerderung der Angewandten Forschung E.V.Inventors: Frank Melchior, Jan Langhammer, Thomas Roeder, Katrin Reichelt, Sandra Brix

Patent number: 7668611Abstract: 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.Type: GrantFiled: August 17, 2007Date of Patent: February 23, 2010Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Katrin Reichelt, Gabriel Gatzsche, Thomas Heimrich, Kai-Uwe Sattler, Sandra Brix
