  • Patent number: 11962991
    Abstract: Systems and methods discussed herein can change a frame of reference for a first spatial audio signal. The first spatial audio signal can include signal components representing audio information from different depths or directions relative to an audio capture location associated with an audio capture source device with a first frame of reference relative to an environment Changing the frame of reference can include receiving a component of the first spatial audio signal, receiving information about a second frame of reference relative to the same environment, determining a difference between the first and second frames of reference, and, using the determined difference between the first and second frames of reference, determining a first filter to use to generate at least one component of a second spatial audio signal that is based on the first spatial audio signal and is referenced to the second frame of reference.

  • Publication number: 20220328062
    Abstract: A method comprises: obtaining a mixed soundtrack that includes dialogue mixed with non-dialogue sound; converting the mixed soundtrack to comparison text; obtaining reference text for the dialogue as a reference for intelligibility of the dialogue; determining a measure of intelligibility of the dialogue of the mixed soundtrack to a listener based on a comparison of the comparison text against the reference text; and reporting the measure of intelligibility of the dialogue.

  • Publication number: 20220166396
    Abstract: Embodiments of systems and methods for adaptive sound equalization in personal hearing devices are disclosed. In some embodiments a microphone in a personal hearing device receives sound from the listener's environment. The sound then is analyzed to determine one or more desired targets, for instance loudness level or spectral balance. The determined targets then are used to control adaptive processing of the sound received by the microphone to generate a perceptually improved sound to render to the listener.

  • Patent number: 11190877
    Abstract: Embodiments of systems and methods are described for reducing undesired leakage energy produced by a non-front-facing speaker in a multi-speaker system. For example, the multi-speaker system can include an array of forward-facing speakers, one or more upward-facing speakers, and/or one or more side-facing speakers. Filters coupled to any two of the speakers in the multi-speaker system can generate audio signals output by the coupled speakers to reduce, attenuate, or cancel a portion of an audio signal output by one or more non-front-facing speakers that acoustically propagates along a direct path from the respective non-front-facing speaker to a listening position in a listening area in front of the multi-speaker system.

  • Patent number: 10887716
    Abstract: A method and a system for calibrating a surround sound system are disclosed. The calibration system can provide a graphical user interface for display comprising a visual representation of the room hosting a multichannel surround sound system. The graphical user interface can permit user input of gestures to place or make changes to the placement of icons representing one or more loudspeakers and a listener. The calibration system can estimate the positions of the one or more loudspeakers or the listener based on the placement of the icons in the model room. A spatial calibration based on the estimated positions can then be performed such that the multichannel surround sound system can render sound scenes more accurately.

  • Patent number: 10869152
    Abstract: The present subject matter provides technical solutions to technical problems facing audio virtualization. To reduce the technical complexity and computational intensity facing audio virtualization, a technical solution includes rendering audio objects binaurally with differing quality levels, where the quality level for each audio source may be selected based on their position relative to the user's field of view. In an example, this technical solution reduces technical complexity and computational intensity by reducing the audio quality for audio sources outside of a user's central field of vision. In an example, high quality audio rendering may be applied to sound objects within this strong central visual acuity area. These technical solutions reduce processing over higher complexity systems, and provides potential for much higher quality rendering at a reduced technical and computational cost.

  • Publication number: 20200367008
    Abstract: A system and method for accurately rendering a virtual sound source at a specified location is disclosed. The sound source is rendered through loudspeakers while visual content is rendered on the screen of a device (such as a tablet computing device or a mobile phone). Embodiments of the system and method estimate both the device pose and the listener pose and render the sound source through loudspeakers or headphones in accordance with the listener pose. The sound source is rendered to the listener such that the perceived location does not change if the device pose is changed, for instance by rotation or translation of the device.

  • Patent number: 10820134
    Abstract: The method and apparatus described herein make use of multiple sets of head related transfer functions (HRTFs) that have been synthesized or measured at various distances from a reference head, spanning from the near-field to the boundary of the far-field. Additional synthetic or measured transfer functions maybe used to extend to the interior of the head, i.e., for distances closer than near-field. In addition, the relative distance-related gains of each set of HRTFs are normalized to the far-field HRTF gains.
