AES67
HEAR... THERE AND EVERYWHERE
AES67 may be an IP audio standard, but it didn’t take long for the various brand permuta ons to suck up all the oxygen in the room. These aren’t standards per se. They are IP audio network systems, WheatNet-IP included, that incorporate AES67 as a subset among other func ons and connec vity op ons. So while you will have to forgive us for prosely zing our respec ve brands, it’s important to understand the signi cance of so many audio networks adop ng and sharing this interoperability standard.
AES67 is everywhere. It’s in every major audio network, including our WheatNet-IP, which means you’ll be able to transport audio between all these systems and other devices and peripheral gear that are connected to them. This IP audio transport standard was ra ed in 2013 by the AES X-192 task force, of which Wheatstone was a member.
But, AES67 is by no means a complete interoperability standard. It doesn’t provide for discovery and control, both of which are needed for any kind of inter-func onality to take place. These standards are in the works, but in the mean me, turning devices on and o , controlling peripheral gear from the console, signaling when a source is ready for air play, and controlling the playout system with a fader – these are all func ons of WheatNet-IP and similar audio networks. In the case of WheatNet-IP, for example, a single Ethernet cable carries the real- me audio stream as well as network and device control messages and other metadata. AES67 covers the audio streams only.
With all this in mind, here are straigh orward answers to the more common ques ons our engineers receive on AES67.
