    Abstract: An illustrative audio processing system identifies an experience location with which an augmented reality presentation device is associated. The experience location is included within a multizone augmented reality space that is presented by the augmented reality presentation device. The audio processing system determines that the experience location is within both a first sound zone and a second sound zone of the multizone augmented reality space, and, based on the determining that the experience location is within both the first and second sound zones, generates a binaural audio stream for presentation by the augmented reality presentation device. The binaural audio stream includes an environmental audio component implemented by a mix of a first environmental audio stream associated with the first sound zone and a second environmental audio stream associated with the second sound zone. Corresponding methods and systems are also disclosed.

    Abstract: An exemplary audio processing system accesses audio stream data representative of a plurality of virtual sounds that virtually originate within an extended reality world and include real-time captured speech originating from a speaking user experiencing the extended reality world and a prerecorded or synthesized sound originating from a real audio source. The audio processing system also accesses acoustic propagation data representative of characteristics that affect propagation within the extended reality world of the virtual sounds to a listening avatar. As the virtual sounds propagate to the listening avatar, the audio processing system renders, based on the audio stream data and the acoustic propagation data, a composite binaural audio stream that represents simulated reproductions of the virtual sounds. The simulated reproductions of the virtual sounds are customized to account for the characteristics that affect the propagation of the virtual sounds to the listening avatar. Corresponding systems and methods are also disclosed.

    Abstract: An illustrative collaboration space provider system provides a virtual collaboration session that allows for audio communication between a user and one or more other users virtually located within a virtual collaboration space. The user is represented by an avatar located at an avatar location within the virtual collaboration space. The collaboration space provider system receives user input from the user, the user input representative of a voice origination location that is within the virtual collaboration space and is distinct from the avatar location. During the virtual collaboration session, the collaboration space provider system simulates propagation within the virtual collaboration space of a voice communication spoken by the user. The propagation of the voice communication is simulated to originate from the voice origination location and not from the avatar location. Corresponding methods and systems are also disclosed.

    Abstract: An exemplary acoustics generation system accesses acoustic propagation data representative of characteristics affecting propagation of a virtual sound to an avatar within an extended reality world being experienced by a user associated with the avatar. Based on the acoustic propagation data, the acoustics generation system also generates a binaural audio signal representative of the virtual sound as experienced by the avatar when the propagation of the virtual sound to the avatar is simulated in accordance with the characteristics affecting the propagation. Additionally, the acoustics generation system prepares the binaural audio signal for presentation to the user as the user experiences the extended reality world by way of the avatar. Corresponding methods and systems are also disclosed.

    Abstract: An exemplary frequency-domain encoder system accesses a set of encoder parameters. The frequency-domain encoder system also accesses time-domain data representative of a content instance. In accordance with the set of encoder parameters, the frequency-domain encoder system transforms the time-domain data into frequency-domain data representative of the content instance. The frequency-domain data includes a plurality of complex coefficients each representing different frequency components of a plurality of frequency components incorporated by the content instance. Also in accordance with the set of encoder parameters, the frequency-domain encoder system generates a frequency-domain data container that includes, in a predefined data container format, the complex coefficients of the frequency-domain data and metadata descriptive of the frequency-domain data.

    Abstract: An exemplary speech presentation system receives a simulated binaural audio signal merging together a plurality of concurrent speech instances originating from a plurality of different speakers speaking concurrently. The speech presentation system also receives acoustic propagation data representative of respective propagation effects applied, within the simulated binaural audio signal, to each of the concurrent speech instances to simulate propagation of the concurrent speech instances. Based on the acoustic propagation data, the speech presentation system extracts, from the simulated binaural audio signal, a different auto-transcribable speech signal for each of the plurality of concurrent speech instances. Additionally, based on the extracted auto-transcribable speech signals, the speech presentation system generates a different closed captioning dataset for each of the plurality of concurrent speech instances.
