  • Publication number: 20240098438
    Abstract: The present invention is directed to methods and apparatus for translating a first plurality of audio input channels to a second plurality of audio output channels. This includes determining that there is pair-wise coding among any of the first plurality of audio input channels, determining an input/output-mapping matrix for mapping at least a first set of the first plurality of audio input channels to at least a second set of the second plurality of audio output channels; and deriving the second plurality of audio output channels based on first plurality of audio input channels, the input/output-mapping matrix and the determined pair-wise coding. The first plurality of audio input channels represent the same soundfield represented by the second plurality of audio output channels.

  • Patent number: 11924619
    Abstract: An apparatus and method of rendering audio. A binaural signal is split on an amplitude weighting basis into a front binaural signal and a rear binaural signal, based on perceived position information of the audio. In this manner, the front-back differentiation of the binaural signal is improved.

  • Patent number: 11900470
    Abstract: A first inspection of insured property is performed to detect hazardous conditions related to the insured property. This first inspection is performed using a first set of imagery data received from one or more imagery data sources. One or more preventive measures are recommended to address the detected hazardous conditions based on analysis of the first set of imagery data. A second inspection is performed using a second set of imagery data received from the imagery data sources. The second inspection is performed to verify that recommended preventive measures have been taken. The first and second sets of imagery data may contain satellite and aerial imagery. The imagery data sources may provide information such as an image of an insured property's roof, an image of a terrain surrounding the insured property, or any other aerial images.

  • Publication number: 20230091218
    Abstract: A system and method of modifying a binaural signal using headtracking information. The system calculates a delay, a first filter response, and a second filter response, and applies these to the left and right components of the binaural signal according to the headtracking information. The system may also apply headtracking to parametric binaural signals. In this manner, headtracking may be applied to pre-rendered binaural audio.

  • Patent number: 11308969
    Abstract: A method performed in an audio decoder for decoding M encoded audio channels representing N audio channels is disclosed. The method includes receiving a bitstream containing the M encoded audio channels and a set of spatial parameters, decoding the M encoded audio channels, and extracting the set of spatial parameters from the bitstream. The method also includes analyzing the M audio channels to detect a location of a transient, decorrelating the M audio channels, and deriving N audio channels from the M audio channels and the set of spatial parameters. A first decorrelation technique is applied to a first subset of each audio channel and a second decorrelation technique is applied to a second subset of each audio channel. The first decorrelation technique represents a first mode of operation of a decorrelator, and the second decorrelation technique represents a second mode of operation of the decorrelator.

  • Patent number: 11269151
    Abstract: An enclosure includes a base and at least three members joined to the base, each member having inner and outer walls and extending upward from the base to form at least a first opening and a second opening along an outer surface formed by the outer walls of the members and an interior space bounded by the inner walls, where the first opening and the second opening are wide enough to accommodate one or more cables routed from the first opening to the second opening along the inner wall of the member positioned between the first opening and the second opening, and where the inner wall positioned between the first opening and the second opening has a radius of curvature that prevents a cable routed from the first opening to the second opening along the inner wall from bending beyond a minimum bend radius.

  • Patent number: 10893375
    Abstract: A method of encoding channel or object based input audio for playback, the method including the steps of: (a) initially rendering the channel or object based input audio into an initial output presentation; (b) determining an estimate of the dominant audio component from the channel or object based input audio and determining a series of dominant audio component weighting factors for mapping the initial output presentation into the dominant audio component; (c) determining an estimate of the dominant audio component direction or position; and (d) encoding the initial output presentation, the dominant audio component weighting factors, the dominant audio component direction or position as the encoded signal for playback.
