Claim 20:
21. A non-transitory computer-readable recording medium comprising instructions that cause a connected speaker comprising:
a LAN interface;
a WPAN interface;
pairing means designed to pair the connected speaker with one or more external speakers each equipped with an external WPAN interface;
processing means designed to acquire an input audio signal from an audio source via the LAN interface, to produce at least one distributed audio signal from the input audio signal, to allocate each distributed audio signal to one of the external speakers paired with the connected speaker, and to transmit, to each external speaker, via the WPAN interface of the connected speaker and the external WPAN interface of said external speaker, the distributed audio signal that is allocated to said external speaker, such that the connected speaker and the external speakers form a multichannel audio playback system,
the connected speaker furthermore being designed to evaluate a transmission and playback latency resulting from the transmission of a distributed audio signal to an external speaker via the WPAN interface and from the playback of the distributed audio signal by the external speaker, the evaluation of the transmission and playback latency being used to ensure synchronized playback by the multichannel audio playback system, to execute the steps of the audio playback method according to claim 20.
