Abstract
This document describes techniques for synchronizing rendering of multi-channel audio output. First audio data corresponding to a first audio channel and second audio data corresponding to a second audio channel may be received. The first and second audio data may be configured for simultaneous rendering. A transmission schedule for wirelessly transmitting audio data to each of first and second audio rendering devices may be configured, according to which the first audio data may be scheduled for transmission to the first audio rendering device after the second audio data is scheduled for transmission to the second audio rendering device by a first length of time. An indication may be wirelessly transmitted to the second audio rendering device to delay rendering audio data by the first length of time. The first and second audio data may be wirelessly transmitted to the first and second audio rendering devices according to the transmission schedule.
