Methods and apparatus for rendering audio objects

Multiple virtual source locations may be defined for a volume within which audio objects can move. A set-up process for rendering audio data may involve receiving reproduction speaker location data and pre-computing gain values for each of the virtual sources according to the reproduction speaker location data and each virtual source location. The gain values may be stored and used during “run time,” during which audio reproduction data are rendered for the speakers of the reproduction environment. During run time, for each audio object, contributions from virtual source locations within an area or volume defined by the audio object position data and the audio object size data may be computed. A set of gain values for each output channel of the reproduction environment may be computed based, at least in part, on the computed contributions. Each output channel may correspond to at least one reproduction speaker of the reproduction environment.

Hearing assistance device incorporating virtual audio interface for therapy guidance

A hearing assistance device adapted to be worn by a wearer comprises a processor configured to generate a sequence of audio cues that audibly guide the wearer through a series of actions involving the wearer's head and neck in accordance with a predetermined corrective or therapeutic maneuver. A speaker is configured to play back the sequence of audio cues for reception by the wearer. One or more sensors are configured to sense movement of the head during each of the actions. The processor is configured to determine if head movement for an action associated with each audio cue has been correctly executed by the wearer, and produce an output indicative of successful or unsuccessful execution of the actions by the wearer.

MODIFYING AUDIO DATA TRANSMITTED TO A RECEIVING DEVICE TO ACCOUNT FOR ACOUSTIC PARAMETERS OF A USER OF THE RECEIVING DEVICE

A communication system provides audio content to one or more client devices capable of playing spatialized audio content. For example, the communication system receives audio content from a client device and transmits the audio content to other client devices to be played for users. The communication system dynamically modifies audio content transmitted to different client devices based on a payload including audio parameters (e.g., local area acoustic properties, an audiogram for a user, a head related transfer function for a user, etc.) received from a client device.

A display apparatus is provided. The display apparatus includes a display panel comprising a plurality of pixels, a driver configured to drive the display panel, and at least one processor. The at least one processor may, based on receiving content comprising video content and audio content, obtain sound location information based on multi-channel information included in the audio content, identify one area of the video content corresponding to the obtained sound location information, and control the driver to adjust brightness of pixels included in the identified one area.

METHODS AND SYSTEMS FOR SPATIAL RENDERING OF MULTI-USER VOICE COMMUNICATION

An illustrative application executing on a first device establishes a first network connection between the first device and a collaboration platform server managing a set of components for a collaboration platform providing voice communication services with respect to a virtual space. Using the first network connection, the application: 1) sets a first location within the virtual space at which a first voice component is positioned, and 2) determines a second location within the virtual space at which a second voice component is positioned. The application receives, by way of a second network connection between the first and second devices, audio data representing voice communication originating at the second device. Based on the first and second locations, the application generates a spatialized rendering of the audio data for presentation to a user. Corresponding methods and systems are also disclosed.

ENHANCEMENT OF SPATIAL AUDIO SIGNALS BY MODULATED DECORRELATION

Some methods involve receiving an input audio signal that includes N input audio channels, the input audio signal representing a first soundfield format having a first soundfield format resolution, N being an integer ≥2. A first decorrelation process may be applied to two or more of the input audio channels to produce a first set of decorrelated channels, the first decorrelation process maintaining an inter-channel correlation of the set of input audio channels. A first modulation process may be applied to the first set of decorrelated channels to produce a first set of decorrelated and modulated output channels. The first set of decorrelated and modulated output channels may be combined with two or more undecorrelated output channels to produce an output audio signal that includes O output audio channels representing a second and relatively higher-resolution soundfield format than the first soundfield format, O being an integer ≥3.

A processing load at a receiving side is reduced in a case where a plurality of classes of audio data is transmitted. A predetermined number of audio streams including coded data of a plurality of groups is generated and a container of a predetermined format having this predetermined number of audio streams is transmitted. Command information for creating a command specifying a group to be decoded from among the plurality of groups is inserted into the container and/or the audio stream. For example, a command insertion area for the receiving side to insert a command for specifying a group to be decoded is provided in at least one audio stream among the predetermined number of audio streams.

An electronic device includes one or more pose sensors for detecting a pose of a user of the electronic device relative to a first physical environment and is in communication with one or more audio output devices. While a first pose of the user meets first presentation criteria, the electronic device provides audio content at a first simulated spatial location relative to the user. The electronic device detects a change in the pose of the user from the first pose to a second pose. In response to detecting the change in the pose of the user, and in accordance with a determination that the second pose of the user does not meet the first presentation criteria, the electronic device provides audio content at a second simulated spatial location relative to the user that is different from the first simulated spatial location.
