AES67-2015, Audio-over-IP network interoperability, Revision published

AES67-2015 AES standard for audio applications of networks - High-performance streaming audio-over-IP interoperability, has been published, revising AES67-2013.

This standard defines an interoperability mode for transport of high-performance audio over networks based on the Internet Protocol. For the purposes of the standard, high-performance audio refers to audio with full bandwidth and low noise. These requirements imply linear PCM coding with a sampling frequency of 44,1 kHz and higher and resolution of 16 bits and higher. High performance also implies a low-latency capability compatible with live sound applications. The standard considers latency performance of 10 milliseconds or less.  This standard provides comprehensive interoperability recommendations in the areas of synchronization, media clock identification, network transport, encoding and streaming, session description and connection management.

This revision of the 2013 standard includes minor changes identified during 'plugfest' testing in October 2014 and includes updated references to RFC 7273, and clarifications in 6.3, 8.1, and 8.5.
