Abstract
A device includes one or more processors configured to execute instructions to obtain, at a first audio output device, first spatial audio data and a first reference time associated, and to cause the first reference time and data representing at least a portion of the first spatial audio data to be transmitted from the first audio output device. The instructions further cause the one or more processors to receive, at the first audio output device from a second audio output device, second spatial audio data and a second reference time. The instructions further cause the one or more processors to, based on the first reference time and the second reference time, time-align the first spatial audio data and the second spatial audio data to generate combined audio data representing a three-dimensional (3D) sound field and to generate audio output based on the combined audio data.
