1. A method comprising:
with a wearable device comprising a first processor, receiving, from a companion device separate from the wearable device and comprising a second processor, spatial audio data and a first pose estimate corresponding to the wearable device that are generated by the second processor of the companion device;
with the first processor of the wearable device, generating a second pose estimate corresponding to the wearable device based on updating the first pose estimate;
with the first processor of the wearable device, refining the spatial audio data based on the second pose estimate; and
with the wearable device, producing sound based on the refined spatial audio data.
