A HRTF used for 3D spatialized audio is combined with, e.g., by concatenation, additional settings to provide a more comfortable, accessible, and enjoyable experience for a listener such as a player of a computer game listening to audio through a headset. A single transfer function is thus created that includes the other settings, and once the transfer function is computed the run-time processing can be treated as a single combined transfer function rather than multiple separate stages, resulting in computational savings. The additional settings pertain to hearing aids normally worn by the listener as well as a room-related function specific to a particular listening venue.

Disclosed herein are systems and methods for presenting audio content in mixed reality environments. A method may include receiving a first input from an application program; in response to receiving the first input, receiving, via a first service, an encoded audio stream; generating, via the first service, a decoded audio stream based on the encoded audio stream; receiving, via a second service, the decoded audio stream; receiving a second input from one or more sensors of a wearable head device; receiving, via the second service, a third input from the application program, wherein the third input corresponds to a position of one or more virtual speakers; generating, via the second service, a spatialized audio stream based on the decoded audio stream, the second input, and the third input; presenting, via one or more speakers of the wearable head device, the spatialized audio stream.

A device includes a memory configure to store instructions and one or more processors configured to execute the instructions to obtain spatial audio data at a first audio output device. The one or more processors are further configured to perform data exchange, between the first audio output device and a second audio output device, of exchange data based on the spatial audio data. The one or more processors are also configured to generate first monaural audio output at the first audio output device based on the spatial audio data.

The present invention provides a method for processing audio data, comprising providing input audio data containing a mixture of different timbres, decomposing the input audio data to generate decomposed data representing a predetermined timbre selected from the timbres contained in the input audio data, determining a set point position of a virtual sound source outputting the predetermined timbre relative to a position of a virtual listener, and generating stereophonic output data based on the decomposed data and the determined set point position.

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.

In general, the present embodiments relate to a method and apparatus for estimating spatial content of a soundfield at a desired location, including a location that has actual sound content obstructed or distorted. According to certain aspects, the present embodiments aim at presenting a more natural, spatially accurate sound, for example to a user at the desired location who is wearing a helmet, mimicking the sound a user would experience if they were not wearing any headgear. Modes for enhanced spatial hearing may be applied which would include situation-dependent processing for augmented hearing. According to other aspects, methods and apparatuses record or capture the sound experienced by a number of the participants and devices on and near the field of play, analyze the captured sound for its various components and their associated spatial content, and make those components available to participants and spectators.

A method for rendering a spatial audio signal that represents a sound field in a selectable viewpoint audio environment that includes one or more audio objects associated with respective audio content and a respective position in the audio environment. The method includes receiving an indication of a selected listening position and orientation in the audio environment; detecting an interaction concerning a first audio object on basis of one or more predefined interaction criteria; modifying the first audio object and one or more further audio objects linked thereto; and deriving the spatial audio signal that includes at least audio content associated with the modified first audio object in a first spatial position of the sound field that corresponds to its position in the audio environment in relation to said selected listening position and orientation, and audio content associated with the modified one or more further audio objects.

A system for and a method of generating an audio image for use in rendering audio. The method comprises accessing an audio stream; accessing positional information, the positional information comprising a first position, a second position and a third position; and generating an audio image. In some embodiments, generating the audio image comprises generating, based on the audio stream, a first virtual wave front to be perceived by a listener as emanating from the first position; generating, based on the audio stream, a second virtual wave front to be perceived by the listener as emanating from the second position; and generating, based on the audio stream, a third virtual wave front to be perceived by the listener as emanating from the third position.

Systems, apparatuses and methods may provide away to render augmented reality and virtual reality (VR/AR) environment information. More particularly, systems, apparatuses and methods may provide a way to selectively suppress and enhance VR/AR renderings of n-dimensional environments. The systems, apparatuses and methods may deepen a user's VR/AR experience by focusing on particular feedback information, while suppressing other feedback information from the environment.

An apparatus for reproducing a spatially extended sound source having a defined position or orientation and geometry in a space has an interface for receiving a listener position. The apparatus having a projector for calculating a projection of a two- or three-dimensional hull associated with the sound source onto a projection plane using the listener position, information on the geometry of the sound source, and on the position of the sound source; a sound position calculator for calculating positions of at least two sound sources for the spatially extended sound source using the projection plane; and a renderer for rendering the at least two sound sources at the positions to obtain a reproduction of the sound source having two or more output signals, configured to use different sound signals for the different positions.
