Abstract: A device includes one or more processors configured to receive, via wireless transmission from a playback device, data associated with a pose of the playback device. The one or more processors are also configured to select, based on the data, a particular representation of a sound field from a plurality of representations of the sound field. Each respective representation of the sound field corresponds to a different sector of a set of sectors. A sector represents a range of values associated with movement of the playback device. The one or more processors are further configured to generate audio data corresponding to the selected representation of the sound field. one or more processors are also configured to send, via wireless transmission, the audio data as streaming data to the playback device.

Abstract: A device includes one or more processors configured to obtain sound information from an audio source. The one or more processors are further configured to select, based on a latency criterion associated with a playback device, a compression mode in which a representation of the sound information is compressed prior to transmission to the playback device or a bypass mode in which the representation of the sound information is not compressed prior to transmission to the playback device. The one or more processors are further configured to generate audio data that includes, based on the selected one of the compression mode or the bypass mode, a compressed representation of the sound information or an uncompressed representation of the sound information. The one or more processors are also configured to send the audio data as streaming data, via wireless transmission, to the playback device.

Abstract: A device includes a memory configured to store first audio data and second audio data. The device also includes one or more processors coupled to the memory and configured to determine priorities of audio sources of an audio scene. The one or more processors are also configured to render, using an object renderer, the first audio data to generate a first audio signal. The first audio data represents a first audio source associated with a first priority. The one or more processors are further configured to render, using a first ambisonics renderer, the second audio data to generate a second audio signal. The second audio data represents a second audio source associated with a second priority.

Abstract: 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.

Abstract: According to a particular implementation of the techniques disclosed herein, a device includes a memory configured to store data corresponding to multiple candidate channel positions. The device also includes one or more processors coupled to the memory and configured to obtain audio data that represents one or more audio sources. The one or more processors are configured to obtain early reflection signals based on the audio data and spatialized reflection parameters. The one or more processors are configured to pan each of the early reflection signals to one or more respective candidate channel position of the multiple candidate channel positions to obtain panned early reflection signals. The one or more processors are also configured to generate an output binaural signal, based on the audio data and the panned early reflection signals, that represents the one or more audio sources with artificial reverberation.

Abstract: 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.

Abstract: A device includes one or more processors configured to receive, via wireless transmission from a streaming device, encoded ambisonics audio data representing a sound field. The one or more processors are also configured to perform decoding of the ambisonics audio data to generate decoded ambisonics audio data. The decoding of the ambisonics audio data includes base layer decoding of a base layer of the encoded ambisonics audio data and selectively includes enhancement layer decoding in response to an amount of movement of the device. The one or more processors are further configured to adjust the decoded ambisonics audio data to alter the sound field based on data associated with at least one of a translation or an orientation associated with the movement of the device. The one or more processors are also configured to output the adjusted decoded ambisonics audio data to two or more loudspeakers for playback.
