Abstract: A device includes one or more processors configured to receive an input audio signal. The one or more processors are also configured to process the input audio signal based on a combined representation of multiple sound sources to generate an output audio signal. The combined representation is used to selectively retain or remove sounds of the multiple sound sources from the input audio signal. The one or more processors are further configured to provide the output audio signal to a second device.

Abstract: Methods, systems, computer-readable media, and apparatuses for manipulating a soundfield are presented. Some configurations include receiving a bitstream that comprises metadata and a soundfield description; parsing the metadata to obtain an effect identifier and at least one effect parameter value; and applying, to the soundfield description, an effect identified by the effect identifier. The applying may include using the at least one effect parameter value to apply the identified effect to the soundfield description.

Abstract: A device and method for backward compatibility for virtual reality (VR), mixed reality (MR), augmented reality (AR), computer vision, and graphics systems. The device and method enable rendering audio data with more degrees of freedom on devices that support fewer degrees of freedom. The device includes memory configured to store audio data representative of a soundfield captured at a plurality of capture locations, metadata that enables the audio data to be rendered to support N degrees of freedom, and adaptation metadata that enables the audio data to be rendered to support M degrees of freedom. The device also includes one or more processors coupled to the memory, and configured to adapt, based on the adaptation metadata, the audio data to provide the M degrees of freedom, and generate speaker feeds based on the adapted audio data.

Abstract: Methods, systems, and devices for processing of multiple audio streams based on available bandwidth are described. Described techniques provide for receiving, at a device, one or more audio streams, identifying an available bandwidth for processing the one or more audio streams, locating (based on the available bandwidth) a first set of one or more objects contributing to the one or more audio streams that are located within a threshold radius from the device, and generating an object-based audio stream. The described techniques further provide for extracting a contribution of the first number of objects from the one or more audio streams, generating an HOA audio stream, and outputting an audio feed that includes the HOA audio stream and the object-based audio stream.
