    Abstract: An exemplary extended reality audio processing system (“processing system”) and an exemplary extended reality audio rendering system (“rendering system”) are disclosed to interoperate with one another to perform near-field and far-field audio reproduction. The processing system accesses audio data representative of virtual sound presented, within an extended reality world, to an avatar of a user experiencing the extended reality world. Based on the audio data, the processing system generates complementary first and second multi-channel audio data streams configured, in combination, to represent the virtual sound.

  • Patent number: 10491179
    Abstract: A method for audio processing includes receiving multiple electrical signals to be transmitted in parallel via multiple respective audio channels. Multiple respective weights are assigned to the multiple electrical signals, wherein at least two of the weights differ from one another. An instantaneous gain is calculated, to be applied to the multiple electrical signals. The instantaneous gain depends on (i) instantaneous amplitudes of the multiple electrical signals, and (ii) the weights assigned to the multiple electrical signals. The instantaneous gain is applied to the multiple electrical signals, and the multiple electrical signals are transmitted via the multiple respective audio channels.

  • Patent number: 10419842
    Abstract: A sound management system for use by a user located within an environment includes a memory device for storing a selection of sounds. The sounds can be music and/or various “colors” of noise (e.g., white, pink, and brown). A controller is used to select one particular stored sound based on a measured biological condition of the user, such as stress or fatigue, or an environmental condition of the environment, such as ambient noise. According to one embodiment, the system is used in conjunction with a sit/stand desk and the sound selection is made in response to changes in the desk height. The selected sound is selected to help abate or mitigate distracting sounds in the environment, such as people talking. The selected sounds are played to the user through headphones worn by the user, or through nearby speakers.

    Abstract: The present aspects relate to audio management for a web browser. For example, an electronic device such as a mobile device may enable a user to navigate to a webpage within a web browser. In some embodiments, the webpage may automatically initiate presentation of audio content. However, the user may wish to quickly silence the audio content that is playing without locating the media player controls of the audio content within the webpage. Accordingly, the present aspects provide audio control for a web browser. Specifically, an audio control affordance may be displayed at a noticeable and recognizable position or area in the web browser, and based on a determination that a webpage includes audio content and/or determination of playback of the audio content. The user may in turn readily adjust a property of the audio content.
