AES67 is the audio-over-IP interoperability standard that lets otherwise-incompatible professional networks — Dante, RAVENNA, Livewire, Q-LAN — exchange uncompressed PCM audio over standard Ethernet/IP. It specifies a common ground: RTP transport, defined sample rates and packet times, and PTP (IEEE 1588) for sample-accurate clock synchronization across the network. The point is freedom from proprietary lock-in: a facility can mix gear from different vendors and have their audio flows interoperate. AES67 is also the audio companion that SMPTE ST 2110-30 builds on for IP video production. For broadcast and live engineers it is the foundation of moving many channels of pristine audio around a building over the same network as everything else.

Audio for Video: A Complete Guide to Sound in Video Products: From Jitter Buffers and Lip Sync to Atmos, Quality Metrics, and Neural Codecs
AES67 lets Dante, RAVENNA and other audio-over-IP systems talk to each other, but only if clocks, packet times and stream setup line up. Volume 5 covers AES67 in detail through what happens to audio on the network: timestamps and clock domains, jitter buffers, packet loss handling and synchronisation with video. Written by Nikolay Sapunov, CEO at Fora Soft.
