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.

An audio output apparatus is disclosed. The audio output apparatus that outputs a multi-channel audio signal through a plurality of speakers disposed at different locations, the audio output apparatus includes an input interface, and a processor configured to, based on the multi-channel audio signal input through the inputter being received, obtain scene information on a type of audio included in the multi-channel audio signal and sound image angle information about an angle formed by sound image of the type of audio included in the multi-channel audio signal based on a virtual user, and generate an output signal to be output through the plurality of speakers from the multi-channel audio signal based on the obtained scene information and sound image angle information, wherein the type of audio includes at least one of sound effect, shouting sound, music, and voice, and a number of the plurality of speakers is equal to or greater than a number of channels of the multi-channel audio signal.

Disclosed are a test instrument and testing methods for audibly providing signal metrics (such as signal strength and/or signal quality) of fifth-generation network (5G) beams to assist installation of 5G Customer Premises Equipment (CPE) antenna at a premises. A test instrument may obtain signal metrics and provide audio output based on the signal metrics at various locations of the premises. The audio output may be transmitted to a headphone device worn by a user. In this manner, the user may select an appropriate location on the premises at which to install the 5G CPE antenna via audible queues that are based on the measured signal metric at a given location. The test instrument may provide fine-tuning capabilities by also audibly providing directional information that indicates where the 5G CPE antenna should be pointed or moved to align the 5G CPE antenna to a 5G beam.

Systems (100) and methods (800) for communicating information. The methods comprise: storing message sets in Communication Devices (“CDs”) so as to be respectively associated with speaker information; performing operations, by a first CD, to capture an audio message spoken by an individual and to convert the audio message into a message audio file; comparing the message audio file to each reference audio file in the message sets to determine whether one of the reference audio files matches the message audio file by a certain amount; converting the audio message into a text message when a determination is made that a reference audio file does match the message audio file by a certain amount; generating a secure text message by appending the speaker information that is associated with the matching reference audio file to the text message, or by appending other information to the text message; transmitting the secure text message.

An apparatus including circuitry configured for: displaying content within a viewport; displaying a symbol representing a sound source within the viewport; detecting one or more gestures that place the displayed symbol in the displayed content; disambiguating between a first placement method, performed for the symbol, that locks the sound source to a position that moves with displayed content moving within the viewport and a second placement method performed for the symbol that is different to the first placement method and locks the sound source to a position that does not move with displayed content moving within the viewport, wherein the first placement method includes a disambiguating gesture relative to the viewport, for the symbol, indicating movement of the symbol relative to the viewport that disambiguates the first placement method from the second placement method.

A sound spatialisation method includes determining digital processing parameters to be applied to sound signals to be broadcast by a set of at least two loudspeakers in order to reproduce a virtual sound source at a desired position, and restoring sound signals by the loudspeakers during which the digital processing parameters are applied to the sound signals. The sound spatialisation method also includes defining a trajectory defined by a set of N points, with two consecutive points of the trajectory being connected together by a curve, and positioning during which the desired position of the virtual sound source is defined on the trajectory.

A method for generating an audio signal associated with a virtual sound source is disclosed. The method comprises obtaining an input audio signal x(t) and modifying the input audio signal x(t) to obtain a modified audio signal. The latter step comprises performing a signal delay operation. Optionally, modifying the input audio signal comprises a signal inverting operation and/or a signal amplification or attenuation and/or a signal feedback operation. The method further comprises generating the audio signal y(t) based on a combination, e.g. a summation, of the input audio signal x(t) and the modified audio signal.

Providing a more natural, physically accurate rendering of the acoustic behavior of a volumetric audio source (e.g., a line-like audio source). In one embodiment, this is achieved by applying a parametric distance-dependent gain function in the rendering process, where the shape of the parametric gain function depends on characteristics of the volumetric audio source.

An apparatus including circuitry configured for receiving a spatial media content file including a plurality of viewpoints; circuitry configured for determining a first viewpoint from the plurality of viewpoints for a first user consuming the spatial media content file; circuitry configured for receiving an indication that affects an audio rendering of the first viewpoint for the first user, wherein the indication is associated with one or more actions of at least one second user consuming the spatial media content file; and circuitry configured for controlling the audio rendering of the first viewpoint for the first user in response to the receiving of the indication based on at least one of: a position and/or orientation of the first user, and the one or more actions of the second user.
