  • Patent number: 10834514
    Abstract: An overlay network platform facilitates a multi-party conference. End users participate in the conference using client-based web browser software. According to this disclosure, an enhanced “audio” experience for a user participating in the conference is provided by rendering different participants' audio in the conference at different positions in a three-dimensional (3D) space. In operation, and given a set of audio streams that comprise the conference and that are being received, a three-dimensional (3D) position for each audio stream in a 3D soundscape is computed. In one embodiment, the 3D position for each audio stream is computed by identifying a target area region of space, and then determining the 3D position for each stream in the target area region of space. The relative 3D positions may be determined based on contextual information related to the content of an audio stream, as well as a computed “relevance” of one stream versus another.

  • Patent number: 10803843
    Abstract: A computer user interface (UI) is capable of generating a sound when a predetermined event occurs. The sound generated when the predetermined event occurs may possess at least some characteristics of a predominant natural language used by a user and/or a location of a computer implementing the UI. This enables the user to quickly assimilate the sound generated when the predetermined event occurs. Because the user quickly assimilates the sound generated when the predetermined event occurs, the user is able to rapidly respond to the predetermined event, at times using the computer UI, which reduces undesirable memory use, processor use and/or battery drain associated with a computing device that implements the computer UI.

  • Patent number: 10798515
    Abstract: An audio system captures audio data of test sounds through a microphone of a headset worn by a user. The test sounds are played by an external speaker, and the audio data includes audio data captured for different orientations of the headset with respect to the external speaker. A set of head-related transfer function (HRTFs) is calculated based at least in part on the audio data of the test sounds at the different orientations of the headset. A portion of the set of HRTFs is discarded to create an intermediate set of HRTFs. The discarded portion corresponding to one or more distortion regions that are based in part on wearing the headset. One or more HRTFs are generated that correspond to the discarded portion using at least some of the intermediate set of HRTFs to create an individualized set of HRTFs for the user.
