Abstract: An audio output device case that includes one or more input devices and is in communication with at least one or more audio output devices and an audio source, performs a method, while the audio source is in communication with the one or more audio output devices, that includes receiving an input via the one or more input devices of the audio output device case, and in response to receiving the input, causes the one or more audio output devices to perform an operation associated with the received input while maintaining communication of the audio source with the one or more audio output devices.

Abstract: A media system and a method of using the media system to reproduce spatial audio based on head-to-torso orientation, are described. The method includes determining a head-to-source orientation and a head-to-torso orientation based on head orientation data generated by a head tracking device. Determining the head-to-torso orientation includes determining torso movements based on movements of the head. The torso can be determined to move when the head movements meet a head movement condition, such as a predetermined angle of movement or pattern of movement. A binaural audio filter that is based on a head-related transfer function corresponding to both the head-to-source orientation and the head-to-torso orientation is applied to an audio input signal to generate an audio output signal. The audio output signal is played to accurately recreate spatial audio having sounds emitted to the user by a sound source. Other aspects are also described and claimed.

Abstract: A binaural sound reproduction system, and methods of using the binaural sound reproduction system to dynamically re-center a frame of reference for a virtual sound source, are described. The binaural sound reproduction system may include a reference device, e.g., a mobile device, having a reference sensor to provide reference orientation data corresponding to a direction of the reference device, and a head-mounted device, e.g., headphones, having a device sensor to provide device orientation data corresponding to a direction of the head-mounted device. The system may use the reference orientation data to determine whether the head-mounted device is being used in a static or dynamic use case, and may adjust an audio output to render the virtual sound source in an adjusted source direction based on the determined use case. Other embodiments are also described and claimed.

Abstract: An audio system and a method of using the audio system to determine an interaural head-related transfer function (HRTF) parameter, are described. The audio system can generate binaural recordings using microphones that are worn by a user in everyday scenarios. The audio system can measure interaural parameter values of selected segments of the recordings, and the measurements can be accumulated over time. The interaural HRTF parameter can be estimated based on the measurements. The interaural HRTF parameter can be used to adapt a generic HRTF to generate an individualized HRTF for the user. Other aspects are also described and claimed.

Abstract: An audio system and a method of using the audio system to generate a head-related transfer function (HRTF) map, are described. The audio system can determine one or more HRTF and corresponding HRTF locations along an azimuthal path of an azimuth extending around a head of a user. The HRTFs or HRTF locations can be measured, and other HRTFs or HRTF locations can be interpolated or extrapolated. The HRTF map can include the HRTFs assigned to HRTF locations along the azimuth. HRTFs from the HRTF map are used to render spatial audio to the user. Other aspects are also described and claimed.

Abstract: A presence of a person within a camera field of view of an electronic device is determined by digitally processing images captured by a camera. A position of a body member of the person with respect to the electronic device is also computed by digitally processing the camera captured images. A crosstalk cancellation (XTC) signal is adjusted based on the computed position of the body member. Adjusting the XTC signal includes adjusting a first predetermined model location, which includes a location at which a user should be in order to achieve a desired virtual acoustics effect. Processing program audio based on the adjusted XTC signal, to generate audio signals that drive speakers. Other aspects are also described and claimed.
