    Abstract: A device includes a memory configured to store instructions. The device also includes a processor configured to execute the instructions to obtain spatial audio data representing audio from one or more sound sources. The processor is also configured to execute the instructions to generate first directional audio data based on the spatial audio data. The first directional audio data corresponds to a first arrangement of the one or more sound sources relative to an audio output device. The processor is further configured to generate second directional audio data based on the spatial audio data. The second directional audio data corresponds to a second arrangement of the one or more sound sources relative to the audio output device. The second arrangement is distinct from the first arrangement. The processor is also configured to generate an output stream based on the first directional audio data and the second directional audio data.

    Abstract: One or more processors may obtain a first distance between a first audio zone of the two or more audio zones associated with the one or more interest points within the first audio zone, and a first device position of a device, obtain a second distance between a second audio zone of the two or more audio zones associated with the one or more interest points within the second audio zone, and the first device position of the device, and obtain an updated first distance and updated second distance after movement of the device has changed from the first device position to a second device position. The one or more processor(s) may independently control the first audio zone and the second audio zone, such that the audio data within the first audio zone and the second audio zone are adjusted based on the updated first distance and updated second distance.

    IPC: H04S7/00

    Abstract: A device includes a memory configured to store data associated with an immersive audio environment and one or more processors configured to obtain pose data for a listener in the immersive audio environment. The processor(s) are configured to determine a current listener pose based on the pose data and one or more pose constraints. The processor(s) are configured to obtain pose data based on the pose update parameter. The processor(s) are configured to obtain, based on the current listener pose, a rendered asset associated with the immersive audio environment. The processor(s) are configured to generate an output audio signal based on the rendered asset.

    Abstract: A device includes a memory configured to store audio data associated with an immersive audio environment. The device also includes one or more processors configured to obtain a listener pose in the immersive audio environment. The one or more processors are configured to determine whether an asset associated with the listener pose is stored locally at the memory. The one or more processors are configured to, based on the determination, select whether to retrieve the asset from the memory or to obtain the asset from a remote device. The one or more processors are also configured to generate an output audio signal based on the asset.

    Abstract: A device includes a memory configured to store untransformed ambisonic coefficients at different time segments. The device also includes one or more processors configured to obtain the untransformed ambisonic coefficients at the different time segments, where the untransformed ambisonic coefficients at the different time segments represent a soundfield at the different time segments. The one or more processors are also configured to apply one adaptive network, based on a constraint, to the untransformed ambisonic coefficients at the different time segments to generate transformed ambisonic coefficients at the different time segments, wherein the transformed ambisonic coefficients at the different time segments represent a modified soundfield at the different time segments, that was modified based on the constraint.

    Abstract: A device includes a memory configured to store data associated with an immersive audio environment and one or more processors configured to obtain contextual movement estimate data associated with a portion of the immersive audio environment. The processor(s) are configured to set a pose update parameter based on the contextual movement estimate data. The processor(s) are configured to obtain pose data based on the pose update parameter. The processor(s) are configured to obtain rendered assets associated with the immersive audio environment based on the pose data. The processor(s) are configured to generate an output audio signal based on the rendered assets.
