Abstract
Described are techniques for distributing audio data to multiple audio devices for generation of a synchronized audio output. A master device may receive audio data from a content server or other remote data source and store the audio data in a local cache. The master device may provide the audio data to multiple slave devices using a single multicast transmission. In some cases, the master device may also provide the audio data to individual slave devices unable to receive the multicast transmission using a network connection. Each slave device may store the audio data in a local cache. To generate the audio output, each audio device may retrieve the audio data from the associated local cache, which may enable the audio data to be distributed without modifying the commands used by audio applications to generate the audio output.
