Abstract

Wired Audio Networking is an established practice since years, based on both proprietary solutions or open hardware and protocols. One of the most cost-effective solutions is the use of a general purpose IEEE 802.3 infrastructure and personal computers running IP based protocols. One obvious shortcoming of such setup is the lack of synchronization at the audio level and the presence of a network delay affected by jitter. Two approaches to sustain a continuous audio flow are described, implemented by the authors in open source projects based on a relative and absolute time adaptive resampling. A description of the mechanisms is provided along with simulated and measured results, which show the validity of both approaches.
