  • Publication number: 20230396950
    Abstract: 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.

  • Patent number: 11671757
    Abstract: 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.

  • Publication number: 20220038838
    Abstract: 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.

  • Patent number: 11032646
    Abstract: 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.

  • Publication number: 20210168552
    Abstract: An audio processor for providing a plurality of loudspeaker signals, or loudspeaker feeds, on the basis of a plurality of input signals, like channeled signals and/or object signals, is configured to obtain information about the position of a listener, to obtain an information about the position of a plurality of loudspeakers, or sound transducers, which may be placed within the same containment, e.g. a soundbar, to dynamically adapt an allocation of objects and/or channel objects and/or adapted signals, like adapted channel signals, derived from the input signals, like channel signals or channel objects, or like upmixed or downmixed signals, to loudspeakers, and to render the objects and/or the channel objects and/or the adapted signals derived from the input signals, in dependence on the information about the positions of the listener and of the loudspeakers, and on the allocation, in order to obtain the loudspeaker signals, such that a rendered sound follows a listener.
