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.

Devices, media, and methods are presented for an audio enhanced augmented reality (AR) experience using an eyewear device. The eyewear device has a microphone system, a presentation system, a support structure configured to be head-mounted on a user, and a processor. The support structure supports the microphone system and the presentation system. The eyewear device is configured to capture, with the microphone system, audio information of an environment surrounding the eyewear device, identify an audio signal within the audio information, detect a direction of the audio signal with respect to the eyewear device, classify the audio signal, and present, by the presentation system, an application associated with the classification of the audio signal.

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.

An audio control system includes at least one microphone, at least one speaker, and one or more processors. The at least one microphone is at a first position adjacent to an ear of a user and configured to detect a sound field at the first position and output a sound signal indicative of the detected sound field. The at least one speaker is at a second position spaced from the first position and configured to output sound responsive to receiving an audio signal. The one or more processors are configured to generate the audio signal based on the sound signal and a target parameter of the sound field at (i) the first position and (ii) a third position spaced from the first position; and provide the audio signal to the at least one speaker to cause the at least one speaker to output the sound responsive to receiving the audio signal.

A monitoring device configured for insertion into a conduit of a subject includes a housing, at least one physiological sensor coupled to the housing, a transmitter coupled to the housing, an expandable element, inflatable element, stretched membrane or balloon coupled to the housing and configured to occlude at least a portion of the conduit, a power source attached to the housing, and a processor coupled to the housing and operatively coupled to memory containing computer instruction causing the monitoring device to obtain physiological information via the at least one physiological sensor where the physiological information includes one or more of pulse rate information, body temperature information, breathing rate information, blood pressure information, cardiac output information, or blood gas level information, and processing and analyzing the physiological information to provide a result.

A system for enabling spatializing audio data is provided. The system analyzes audio data to identify when to generate spatialized audio data. The system can receive incoming audio data including a plurality of channel-based audio signals as well as object-based audio. The system performs an analysis of the audio data and/or metadata associated with the audio data to determine when to generate the spatialized audio data. The system can identify one or more categories associated with the audio data (e.g., stereo, mono, game effect, . . . ) and use the category to determine whether to spatialize the audio data or not spatialize the audio data.

A wearable electronic device (WED) includes one or more sensors and cameras that determine a location of a physical object in a zone where the user is located and that track movement of an electronic device that moves to define a boundary of the zone. The WED includes a processor that generates binaural sound and a display that displays a virtual image of the boundary of the zone and a visual warning that notifies the user of the physical object.

Examples of the disclosure describe systems and methods for presenting an audio signal to a user of a wearable head device. According to an example method, a first input audio signal is received, the first input audio signal corresponding to a source location in a virtual environment presented to the user via the wearable head device. The first input audio signal is processed to generate a left output audio signal and a right output audio signal. The left output audio signal is presented to the left ear of the user via a left speaker associated with the wearable head device. The right output audio signal is presented to the right ear of the user via a right speaker associated with the wearable head device. Processing the first input audio signal comprises applying a delay process to the first input audio signal to generate a left audio signal and a right audio signal; adjusting a gain of the left audio signal; adjusting a gain of the right audio signal; applying a first head-related transfer function (HRTF) to the left audio signal to generate the left output audio signal; and applying a second HRTF to the right audio signal to generate the right output audio signal. Applying the delay process to the first input audio signal comprises applying an interaural time delay (ITD) to the first input audio signal, the ITD determined based on the source location.

An information processing device (100) according to the present disclosure includes: an acquisition unit (141) configured to acquire a first image including a content image of an ear of a user; and a calculation unit (142) configured to calculate, based on the first image acquired by the acquisition unit (141), a head-related transfer function corresponding to the user by using a learned model having learned to output a head-related transfer function corresponding to an ear when an image including a content image of the ear is input.

The description relates to rendering directional sound. One implementation includes receiving directional impulse responses corresponding to a scene. The directional impulse responses can correspond to multiple sound source locations and a listener location in the scene. The implementation can also include encoding the directional impulse responses to obtain encoded departure direction parameters for individual sound source locations. The implementation can also include outputting the encoded departure direction parameters, the encoded departure direction parameters providing sound departure directions from the individual sound source locations for rendering of sound.
