Abstract
Described are techniques for configuring a group of audio devices to provide a synchronized audio output. Values indicative of the data throughput for communication between each audio device and the access point and between the audio devices themselves may be determined. A value indicative of the airtime that would be used to communicate data to other audio devices, via a multicast transmission, may be determined for at least a portion of the audio devices. Based on the airtime values, the audio devices may be divided into subsets, each including a master device configured to provide data to one or more slave devices via a multicast transmission. A global master device that receives audio data from a data source and provides the data to the other master devices may be selected based on the data throughput values for communication between each master device and the access point.
