Two new AoIP protocols announced

Wheatstone Corporation is ready to showcase its new Audio over IP networking at IBC while the AES and EBU are collaborating on developing a next-generation standard.

Wheatstone Corporation and the Audio Engineering Society (in collaboration with the EBU) are each developing new ‘next-generation’ Audio over IP protocols. Wheatstone’s AoIP networking, which will be showcased at the upcoming IBC show, combines logic control and transport for total control of the broadcast studio. “We are taking AoIP one step beyond audio transport with a control layer that gives our WheatNet-IP system distributed intelligence for directing, managing and organizing audio in the broadcast studio,” said Wheatstone’s vice president of engineering Andrew Calvanese. According to the company the WheatNet-IP Intelligent Network is the only AoiP system with control surfaces that have an Ethernet interface, and the only system to include utility mixers in its access units, or BLADEs, for managing audio. Because of this and other features, each component is always linked in and available from anywhere in the WheatNet-IP network, giving broadcasters total control of sources, devices, and even elements within the console. Meanwhile, AES Standards Committee chair Bruce Olson (pictured) has announced the AES and the EBU are collaborating on a new common packet-based AoIP network standard for linear PCM audio. This liaison is officially entitled “Next generation AES/EBU Interface Based On IP Technology.” The collaboration is a continuation of the two organizations’ work on the AES3 standard, first published in 1985, for the transport of digital audio signals between professional devices. The focus of the new work is on audio interoperability over high-performance IP networks, with the further goal of interoperability with the EBU’s common framework for audio contribution over IP, ACIP. Work has already started within the AES with the project known as AES X192. A recently published draft is now being discussed among project participants, including some ACIP2 members, and the project is open to new participants. Further information is available at
