October 2017 Luncheon Report

October 14, 2017

Jeff McGinley of the Telos Alliance gave a presentation on the AES 67 Standard and a preview of the upcoming AES 70.  There were 17 members and guest attending the luncheon at the Old Spaghetti Factory in South Center, Tukwila.  Chapter Chairman Jon Kasprick opened the meeting with a quick report on upcoming meetings and activities.  Jon also announced that the next chapter luncheon would feature Black Magic Design and will be held Wednesday, November 15, at the OSF.

Jeff talked about AES67, the new industry standard for interoperability of high-quality audio over IP networks from the Audio Engineering Society, published September 2013. This standard was quickly embraced by all of the main broadcast audio equipment vendors, and compatibility modes announced by all of the major competing networking audio vendors: Livewire, Q-LAN, Ravenna, and Dante. Outside of broadcast, there has also been a high level of audio industry acceptance.

AES67 specifies the method for carrying uncompressed 24-bit linear audio over layer 3 IP networks. There are options and choices of sample rates, packets sizes, number of channels and bit depths, but a strict interoperability requirement is made so that all vendors must implement at least the one common set of parameter choices. This requirement is what produces the interoperability between all vendors labeling their equipment AES67.
