Synchronisation for Distributed Audio Rendering over Heterogeneous Devices, in HTML5
The HTML5 standard is widespread on mobile devices. In combination with the Web Audio API, it allows for massively distributed real time audio rendering. But timing issues exist, mainly because of the lack of standard inter device synchronisation. This paper proposes a synchronisation solution based on HTML5. Using a shared reference time, we achieved the distributed rendering of audio events with an individual accuracy of 1 to 10 ms, 5 ms in standard deviation, which is more accurate than the audio block duration, for any device that we measured.
