Looking around the North Hall at NAB this year, it is clear that AES 67 is rapidly becoming the "lingua franca" of IP audio networking. There were a number of booths showing live AES 67 demos, including the RAVENNA booth that featured the ARG Quarra PTP switch providing interconnections among a large collection of products from famous audio manufacturers, including Lawo, Ward-Beck, ALC Networks, Genelec and others. The Media Networking Alliance booth showed products from 10 different companies working together, as well as listing 27 companies that are active participants.
