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.
