Patent number: 11563855Abstract: A system controls the audio focus for a user in a virtual conference call. The system retrieves sound parameters associated with participants in the virtual conference call with the user from a user profile of the user. The sound parameters define volume adjustments to be applied to audio data received from the participants for generating an audio mix customized to the user. The system receives the audio data from client devices of the participants, and for each of the participants, adjusts the audio data of the participant using the associated sound parameter of the participant. The system adds the adjusted audio data of the participants to the audio mix for the user and provides the audio mix to a client device of the user.Type: GrantFiled: May 14, 2021Date of Patent: January 24, 2023Assignee: Meta Platforms Technologies, LLCInventors: Igor D. Spivak, Andrew Lovitt

Patent number: 11523247Abstract: Determination of a set of acoustic parameters for a headset is presented herein. The set of acoustic parameters can be determined based on a virtual model of physical locations stored at a mapping server. The virtual model describes a plurality of spaces and acoustic properties of those spaces, wherein the location in the virtual model corresponds to a physical location of the headset. A location in the virtual model for the headset is determined based on information describing at least a portion of the local area received from the headset. The set of acoustic parameters associated with the physical location of the headset is determined based in part on the determined location in the virtual model and any acoustic parameters associated with the determined location.

Publication number: 20220342213Abstract: Embodiments relate to an audio system for various audio applications. The audio system registers the locations of one or more sound sources and selects the target sound source based on a hidden Markov model. A health monitoring system that integrates an audio system may use information collected by sensors to monitor an amount of social interaction of a user and predict a risk of dementia and/or hearing loss based on a model. The audio system uses a current/voltage sensor to detect electrical drive signals for determining a level of audio leakage of the audio system. Additionally, the audio system may update a video stream with an audio background based on an artificial visual background in the video stream so that the updated video stream sounds as if it originated from the user being located in a physical representation related to the background.Type: ApplicationFiled: July 8, 2022Publication date: October 27, 2022Inventors: Hao Lu, William Owen Brimijoin, II, Christi Miller, Limin Zhou, Andrew Lovitt

Patent number: 11462230Abstract: An audio system that includes an IMU or accelerometer in physical proximity to a microphone and a driver. The signal generated by the IMU or accelerometer may be used to filter the audio signal generated by the microphone with respect to mechanically coupling between the driver outputting sound and the microphone via a shared structure. In some cases, an accelerometer may be incorporated into a package of the microphone to provide analog-based filtering prior to converting the audio signal of the microphone to a digital format.Type: GrantFiled: February 8, 2021Date of Patent: October 4, 2022Assignee: Meta Platforms Technologies, LLCInventors: Sebastian Sztuk, Tony David, Andrew Lovitt

Patent number: 11409360Abstract: A method comprising determining a set of position parameters for an inertial measurement unit (IMU) on a headset worn by a user. The set of position parameters includes at least a first yaw measurement and a first roll measurement. The set describes a pointing vector. The method further comprises calculating a drift correction component that describes a rate of correction. The drift correction component is based at least in part on the set of position parameters. The method further comprises applying the drift correction component to one or more subsequent yaw measurements for the IMU.

Publication number: 20210405959Abstract: This disclosure describes embodiments of methods, non-transitory computer-readable media, and systems for detecting that a physical space includes a physical object corresponding to an analogous virtual object from an augmented reality experience and rendering (or otherwise modifying) the augment reality experience to integrate the physical object as part of the experience. In particular, the disclosed systems can determine that a physical object within a physical environment corresponds to an analogous virtual object of an augmented reality experience. Based on this correspondence, the disclosed systems can modify one or more of the virtual graphics, sound, or other features corresponding to the augmented reality experience to represent the virtual object using the physical object. For example, the disclosed systems can modify acoustic features of a sound for the augmented reality experience to simulate the sound originating from (or being affected by) the physical object.Type: ApplicationFiled: June 29, 2020Publication date: December 30, 2021Inventor: Andrew Lovitt
