  • Patent number: 11638093
    Abstract: Controlling temperature of a surface of the electronic device. The electronic device includes: a speaker, an adaptive control circuit configured to receive an audio input signal responsive to an audio input power to the speaker and a temperature sensor configured to sense a temperature internal to the electronic device. A temperature signal responsive to the sensed temperature is input to the adaptive control circuit. Responsive to the audio input signal and the temperature signal a power control signal is computed by the adaptive control circuit so that a temperature of the surface of the electronic device at a later time approaches a previously determined target temperature. An audio limiter is configured to limit the audio input power to the speaker responsive to the power control signal.

  • Patent number: 11620771
    Abstract: Computing a relative-head-orientation relative to a moving-reference. First and second data are received. The first data are indicative of a head-orientation of a head of a user. The second data are indicative of at least one of: a location, a motion, an orientation, a velocity and an acceleration of the user. A head-orientation is computed according to the first data. A moving-reference is updated by an adjustment toward the head-orientation, to produce an updated-moving-reference. The amount of adjustment is indicated by processing the second data. A relative-head-orientation is computed relative to the updated-moving-reference. Binaural audio is rendered in accordance with the relative-head-orientation.

  • Patent number: 11531519
    Abstract: Adjusting gains of an audio mix. Audio tracks using respective gains are individually analyzed to compute a first metric of frequency content. A user input specifies a desired second metric of the frequency content. Responsive to the user input, respective gains of the audio tracks are collectively and simultaneously adjusted to produce respective adjusted gains of the audio tracks. A second audio mix when played of the audio tracks with the respective adjusted gains has a third metric of frequency content different from the first metric of frequency content. The third metric is closer to the second metric than said first metric.

  • Patent number: 11425258
    Abstract: First and second computer systems and respective first and second microphones thereof receive respective portions of a same audio input signal. Audio buffers received respectively from the first and second computer system include data encoded from respective microphone inputs of the first and the second computer systems. The received audio buffers are synchronized and corrected for gain differences between the received audio buffers to produce corrected audio buffers. The corrected audio buffers are mixed into an output buffer. The synchronization reduces echo when the output buffer is played at a remote peer computer system.
