    Abstract: An electronic device communicates with a display, an input device, and a wearable audio output device. The device displays a user interface with dynamic visual representations of participants in a communication session. Outputting, via the wearable audio output device, audio from the plurality of participants in the communication session. The audio is adjusted to maintain simulated spatial locations of participants relative to a frame of reference of the communication session, independently of a position of the wearable audio output device relative to the frame of reference. The simulated spatial locations correspond to the locations of the dynamic visual representations. Receiving an input selecting one of the dynamic visual representations. In response, displaying the dynamic visual representations at locations different from their initial locations, and outputting audio from the participants to position their audio at a different simulated spatial locations, relative to the frame of reference.

    Abstract: Virtualizing speakers for a headphone set can include determining a location of a display. Locations of one or more virtual speakers can be assigned based on the location of the display. A first virtual speaker can be located at the display. A position of a head of a user can be tracked. Audio content can be spatialized with a spatial renderer to generate spatialized audio signals, based on the tracked position of the head and the locations of the virtual speakers. Other aspects are also described and claimed.

    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: An audio processing system has one or more processors that process an audio signal on three paths. The first path has a direct gain and a direct virtual source algorithm operating on the audio signal. The second path has a plurality of early reflection gains operating on the audio signal. Operation with the early reflection gains produces a plurality of early reflections. Each of the early reflection signals may be subjected to a delay and may be processed according to an early reflections virtual source algorithm. The third path has a reverb gain and binaural reverb filters operating on the audio signal. The third path also has a crosstalk canceler. A mixer combines left and right channel outputs of each of the first path, second path and third path. The mixer produces a left loudspeaker signal and a right loudspeaker signal.
