Abstract: In an aspect, a lens is zoomed in to create a zoomed lens. Lens data associated with the lens includes a direction of the lens relative to an object in a field-of-view of the zoomed lens and a magnification of the object resulting from the zoomed lens. An array of microphones capture audio signals including audio produced by the object and interference produced by other objects. The audio signals are processed to identify a directional component associated with the audio produced by the object and three orthogonal components associated with the interference produced by the other objects. Stereo beamforming is used to increase a magnitude of the directional component (relative to the interference) while retaining a binaural nature of the audio signals. The increase in magnitude of the directional component is based on an amount of the magnification provided by the zoomed lens to the object.

Abstract: A device includes a mixer configured to mix first ambisonic data and second ambisonic data to generate mixed ambisonic data. The first ambisonic data and the second ambisonic data correspond to different spatial orders. The device also includes ambisonic adjustment circuitry configured to adjust the mixed ambisonic data based on position data to generate an adjusted mixed ambisonic output.

Abstract: An apparatus includes de-jitter buffer control circuitry configured to determine an arrival delay value based on previously received audio packets, to identify a receive time of a first audio packet of a talk spurt, to determine an offset value of the first audio packet based on the receive time and the arrival delay value, and to adjust a target delay value associated with a de-jitter buffer based on the offset value. The apparatus also includes a de-jitter buffer configured to buffer the first audio packet based on the adjusted target delay value.
