A device includes a memory configured to store instructions. The device also includes a processor configured to execute the instructions to obtain spatial audio data representing audio from one or more sound sources. The processor is also configured to execute the instructions to generate first directional audio data based on the spatial audio data. The first directional audio data corresponds to a first arrangement of the one or more sound sources relative to an audio output device. The processor is further configured to generate second directional audio data based on the spatial audio data. The second directional audio data corresponds to a second arrangement of the one or more sound sources relative to the audio output device. The second arrangement is distinct from the first arrangement. The processor is also configured to generate an output stream based on the first directional audio data and the second directional audio data.

CONVEYING MOTION DATA VIA MEDIA PACKETS

A device includes a memory configured to store instructions and one or more processors configured to execute the instructions to receive a media packet and to determine, based on a field of the media packet, whether the media packet includes motion data. The one or more processors are also configured to execute the instructions to, based on the media packet including motion data, extract the motion data from the media packet.

Modeling Acoustic Effects of Scenes With Dynamic Portals

The description relates to modeling acoustic effects in scenes with dynamic portals. One implementation includes obtaining a representation of a scene having a plurality of portals and simulating sound travel in the scene using a plurality of probes deployed in the scene. The implementation also includes determining acoustic parameters for initial sound traveling between respective probes based at least on the simulating. The implementation also includes identifying one or more intercepted portals in the scene that are intercepted by a particular initial sound path from a particular source location to a particular listener location, using particular acoustic parameters for the particular source location and the particular listener location.

LOW LATENCY, LOW POWER MULTI-CHANNEL AUDIO PROCESSING

An electronic eyewear device includes a display and a speaker system adapted to present augment reality objects and associated sounds in a scene being viewed by the user. A processor receives one or more audio tracks respectively associated with one or more augmented reality objects, encodes the audio tracks into an aggregated audio track including the audio tracks, a header for each audio track that uniquely identifies each respective audio track, and an aggregate header that identifies the number of tracks in the aggregated audio track. The processor transfers the aggregated audio track to an audio processor that uses the header for each audio track and the aggregate header to separate the audio tracks from the aggregated audio track. The audio processor processes the audio tracks independently in parallel and provides the audio tracks to the speaker system for presentation with the augmented reality objects.

20220374197 · 2022-11-24 ·

A computer system displays an audio settings user interface that includes a first user interface element that is activatable to change a current audio output mode of a set of one or more audio output devices. The computer system receives a second set of one or more inputs including an input directed to the first user interface element. In response, the computer system transitions the set of one or more audio output devices from a first audio output mode to a different second audio output mode. In the first audio output mode, audio is output based on a first frame of reference that is a three-dimensional physical environment surrounding the set of one or more audio output devices. In the second audio output mode, audio is output based on a different second frame of reference that is fixed relative to the set of one or more audio output devices.
