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: 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 to perform audio signal equalization includes one or more processors configured to receive impulse response data corresponding to multiple audio channels. Each audio channel is associated with a corresponding microphone of multiple microphones of an audio device and indicative of sound propagation from one or more speakers of the audio device to the corresponding microphone. The one or more processors are configured to generate equalization filter data that is based on the impulse response data and that is indicative of multiple equalization filters. Each of the equalization filters is associated with a corresponding audio channel of the multiple audio channels. The one or more processors are also configured to process the equalization filter data to determine a playback equalization filter to be applied to an audio playback signal prior to playout at the one or more speakers.

Abstract: A device to perform location-based audio signal compensation includes a memory configured to store instructions and one or more processors. The one or more processors are configured to execute the instructions to receive an audio input signal corresponding to sound received from a second device, determine position data indicative of a position of the device, and generate, based on the audio input signal, a compensation filter to be applied to an audio playback signal prior to playout from the second device, to at least partially compensate for distortion associated with sound propagation from the second device to the position of the device.

Abstract: A device to process an audio signal representing output sound includes one or more processors configured to generate, responsive to sensor data indicative of pressure detected at a housing of the device, output data based on a predicted effect of the pressure on an acoustic output of the device. The one or more processors are also configured, responsive to the output data, to adjust operation of an audio playback component that generates the acoustic output.
