Abstract:
1. A method performed by an audio processing device, the method comprising: connecting to one or both of a wide area network (WAN) and a local area network (LAN) via a network interface; receiving audio information over one or both of the WAN and the LAN via the network interface; generating playback timing information for the audio information; dividing the audio information into a series of frames comprising audio content and playback timing information; transmitting audio processing device clock timing information and the series of frames to at least one additional audio processing device over at least the LAN; generating an analog signal based on the audio information; using the audio information, the playback timing information, and the audio processing device clock time information to output the analog signal based on the audio information to a speaker of the audio processing device in synchrony with the at least one additional audio processing device, wherein the audio processing device and the at least one additional audio processing device remain independently clocked during the synchronous output of the analog signal; and transmitting to a user interface module over the LAN, via the network interface, status information comprising a status of a synchrony group, wherein the synchrony group comprises the audio processing device and the at least one additional audio processing device as members.
