Publication number: 20230396950Abstract: A more efficient rendering of audio objects, which allows 3D panning, is achieved by performing the panning into two stages, namely at least one horizontal in-layer panning leading to a first virtual (speaker) position and a second virtual or real (speaker) position, which is vertically offset, and another panning vertically between the two positions. Although acting in such a manner seems to increase the computational complexity, this staged processing increases, in fact, the stability of the rendering and the location of the intended virtual position. Moreover, the staged processing, enables to perform, according to an embodiment, the panning by use of amplitude panning gains only, i.e. phase processing is not necessary, thereby rendering the computational complexity low. Even further, the rendering is flexible with respect to applicability to a variety of loudspeaker setups.Type: ApplicationFiled: August 24, 2023Publication date: December 7, 2023Inventors: Andreas WALTHER, Christof FALLER, Jürgen HERRE, Markus SCHMIDT, Christian BORSS, Julian KLAPP, Philipp GÖTZ

Patent number: 11671757Abstract: An audio processor for providing loudspeaker signals on the basis of input signals, like channel signals and/or object signals, obtains an information about the position of a listener and an information about the position of a plurality of loudspeakers, or sound transducers. The audio processor selects one or more loudspeakers for a rendering of the objects and/or of the channel objects and/or of the adapted signals, derived from the input signals. The selection depends on the information about the position of the listener and about the positions of the loudspeakers and takes into consideration the information about one or more acoustic obstacles. The audio signal processor renders the objects/channel objects/adapted signals derived from the input signals, in dependence on the information about the position of the listener and about positions of the loudspeakers, in order to obtain the loudspeaker signals, such that a rendered sound follows a listener.Type: GrantFiled: February 1, 2022Date of Patent: June 6, 2023Assignee: Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V.Inventors: Andreas Walther, Jürgen Herre, Julian Klapp, Christof Faller, Markus Schmidt

Publication number: 20220038838Abstract: An audio processor for reproducing multichannel audio has a normal layer processing and a lower layer processing. The normal layer processing is configured for processing one or more channels of the object-specific audio or the multichannel audio belonging to a normal layer. The lower layer processing is configured for processing at least one channel or more channels of the object-specific audio or the multichannel audio belonging to a lower layer. The lower layer processing is configured to feed at least one signal belonging to the one channel or the more channels of the lower layer to a subwoofer output.Type: ApplicationFiled: October 14, 2021Publication date: February 3, 2022Inventors: Andreas WALTHER, Yannik GREWE, Julian KLAPP

Patent number: 11032646Abstract: An audio processor configured for generating, for each of a set of one or more loudspeakers, a set of one or more parameters, which determine a derivation of a loudspeaker signal to be reproduced by the respective loudspeaker from an audio signal, based on a listener position and loudspeaker position of the set of one or more loudspeakers. The audio processor is configured to base the generation of the set of one or more parameters for the set of one or more loudspeakers on a loudspeaker characteristic of at least one of the set of one or more loudspeakers.Type: GrantFiled: October 25, 2019Date of Patent: June 8, 2021Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Andreas Walther, Jürgen Herre, Christof Faller, Julian Klapp
