Back in late September a bunch of guys gathered secretly at a lab deeply hidden inside the HQ of Yamaha Professional Audio Division in Buena Park in the Greater Los Angeleas area. The goal was to produce a comprehensive video on AES67, explaining its motivation, architecture and potential use cases. The heart of the production was a real AES67 system, combining RAVENNA, Livewire, QLAN and Dante devices into a common  network setup. The video demonstrates how to create AES67 streams and connect to them within the various system environments and provides tipps for planning and operating mixed AES67 networks.

This short extract covers a brief introduction on how to setup AES67 streams in RAVENNA:

Following on from our earlier success in passing audio streams between devices on the network we felt that tripping over headphone leads or just looking at meters on screen was a little limiting. The next step therefore was to send some audio to a pair of Genelec 4420A loudspeakers.

Last time we connected RAVENNA Virtual Sound Card to the Merging Horus and monitored the output out of the Horus headphone output.

After rushing into our plug fest and then with Christmas getting in the way, our plug fest has been a little delayed.

On our voyage into AES67 we decided to start with RAVENNA as it’s the only fully fledged protocol that is AES67 compatible out of the box. We got hold of a Lawo Crystal and a Merging HAPI and Pyramix. Merging to Merging worked fine but we struggled to put them together with the Crystal. We crashed the network. We didn’t pay sufficient attention to our switch set up.

In the world of audio networking switch set up is really important.

We’ve heard so much in the industry press about AES67. It seems to be the next big thing. There is even a trade association dedicated to it – the Media Networking Alliance. 

RAVENNA already offers AES67 compliance and Audinate has released AES67 firmware to manufacturers leaving it up to them whether to implement the capability into their products.
