AN AUDIO RENDERING SYSTEM

The present invention relates to an audio rendering system; comprising a wireless communications device, a first audio rendering device and a second audio rendering device; wherein the wireless communications device is configured to transmit a first plurality of audio packets to the first audio rendering device and a second plurality of audio packets to the second audio rendering device, the first plurality of audio packets including frames of audio data for a first audio channel from a set of one or more audio channels and the second plurality of audio packets including frames of audio data for a second audio channel from said set of one or more audio channels; wherein the first audio rendering device is configured to maintain a first buffer of received frames of audio data and to release frames of audio data from said first buffer for rendering at respective first buffer release times; wherein the second audio rendering device is configured to maintain a second buffer of received frames of audio data and to release frames of audio data from said second buffer for rendering at respective second buffer release times; wherein the first audio rendering device is configured to receive one or more messages from the second audio rendering device; and wherein at least the first audio rendering device is configured to synchronise the first buffer release times with the second buffer release times based on the received one or more messages.
