1. A method comprising:
centering, using one or more processors, spatial audio in a three-dimensional (3D) virtual audio space;
obtaining, using the one or more processors, first sensor data from an auxiliary device communicatively coupled to a source device, the source device configured to provide the spatial audio and the auxiliary device configured to playback the spatial audio in the 3D virtual audio space;
obtaining, using the one or more processors, second sensor data from one or more motion sensors of the source device;
determining, using the one or more processors, whether the source device and auxiliary device are in a period of mutual quiescence based on the first and second sensor data;
in accordance with determining that the source device and the auxiliary device are in a period of mutual quiescence, re-centering the spatial audio in the 3D virtual auditory space following the period of mutual quiescence; and
rendering, using the one or more processors, the re-centered spatial audio in the 3D virtual auditory space.
