AES 67-2018 PDF Download

The AES 67-2018 standard is aimed at achieving interoperability in high-performance streaming audio-over-IP networks. It focuses on supporting professional quality audio with low latency, suitable for live sound reinforcement. The standard acknowledges that the necessary network performance is readily available on local-area and enterprise-scale networks.

The standard provides recommendations for various aspects of networked audio systems. These include synchronization, media clock identification, network transport, encoding and streaming, session description, and connection management. By following these recommendations, audio systems can operate in an interoperable manner, ensuring compatibility and seamless integration between different networked audio systems.

This revision of the standard incorporates clarifications, minor corrections, and additions. An Annex G has been included, which provides a Protocol Implementation Conformance Statement (PICS). Additionally, a new recommendation for sender keep-alive has been added. Other minor clarifications and corrections cover topics such as specifying MTU requirements, correcting SDP examples, and conforming to IEEE 1588-2008 requirements. These revisions aim to enhance the clarity and correctness of the standard.
