Abstract: A method of managing an audio stream that is read by audio playback equipment in a manner that is synchronized on a reference clock is provided. The method includes the following steps implemented in said piece of audio playback equipment: receiving the audio stream, the audio stream being in the form of packets, each packet comprising a succession of audio samples associated with identification information characteristic of a timestamp of said packet; playing the audio samples contained in each packet and storing a time given by the reference clock that is characteristic of the moment at which a predetermined sample of at least one of the packets is played; and sending a message including correspondence information concerning the correspondence between the identification information characteristic of a timestamp of said packet and the time stored in the preceding step.

Abstract: Connected speaker (1) comprising:
a LAN interface (2);
a WPAN interface (3);
pairing means (5) designed to pair the connected speaker with one or more external speakers (6) each equipped with an external WPAN interface (7);
processing means (8) designed to acquire an input audio signal from an audio source (15) 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 (6) paired with the connected speaker, and to transmit, to each external speaker, via the WPAN interface (3) of the connected speaker (1) and the external WPAN interface (7) of said external speaker (6), the distributed audio signal that is allocated to said external speaker (6), such that the connected speaker (1) and the external speakers (6) form a multichannel audio playback system.
