  • Patent number: 11715479
    Abstract: An audio signal is enhanced using interaural coherence to control noise reduction and binaural cue preservation. Sounds from a local area are detected via an acoustic array. An interaural coherence is determined using the detected sounds. Sound filters for an audio signal are generated based on the interaural coherence. The sound filters implement a tradeoff between increasing signal-to-noise ratio (SNR) between a target source and an interfering source and preserving of binaural information of the interfering source. The tradeoff is controlled based on the interaural coherence. The sound filters are applied to the audio signal to generate audio content. The audio content is presented via a speaker array.

  • Patent number: 11638086
    Abstract: A method and an apparatus for enabling adaptive audio signal alteration are described. When an input audio signal is received, a determination of whether the user of an audio device hears the input audio signal is performed based upon brain activity of the user. A determination of whether the user is distracted by the audio signal is performed based upon sensor measurements indicating a physical state of the user. In response to determining that the user hears the input audio signal and that the input audio signal causes the user to be distracted, a determination of configuration parameter(s) is performed. An alteration of audio signal(s) is caused based upon the configuration parameter(s) to obtain modified version(s) of the audio signal(s) that are intended to address the distraction caused by the input audio signal, and output audio signals are output, where the output audio signals include the modified versions.

    Abstract: A system for dynamically updating a head-related transfer function (HRTF) model that is customized to a user. The system receives one or more images of the user captured by one or more imaging devices. The system determines a pose of the user using the one or more captured images. The pose of the user includes a head-torso orientation of the user. The system updates a HRTF model for the user based on the determined pose including the head-torso orientation. The system generates one or more sound filters using the updated HRTF model and applies the one or more sound filters to audio content to generate spatialized audio content. The system provides the spatialized audio content to the user.
