The AES67 Standard for audio applications of networks - High-performance streaming audio-over-IP interoperability has become the cornerstone of IP based audio applications. It has received wide acceptance among manufacturers and users of networked audio equipment in professional applications. Many users of the standard have requested a logo for use on their products and literature which will quickly and unambiguously identify products that conform to the specification.
The 2018 version of AES67, to be published next month, includes an annex with protocol implementation criteria. Answering the questions in the annex results in a Protocol Implementation Conformance Statement which is a detailed indication of the capabilities of the implementation, stated relative to the common basis for understanding provided by the standard PICS proforma, by the supplier and acquirer, or potential acquirer, of the implementation.
Use of the logo will be on a self-certification basis. Manufacturers must verify that their product conforms to the requirements of the standard before affixing the logo to their product, its literature or their advertising. Further details of the logo and its license terms will be forthcoming.

Waves has joined the AES Standards Sustainer program at the Silver level. Presonus has also joined at the Silver level. Attero Tech has joined the Standards Sustainer program at the basic level. The generosity and support of all three companies is greatly appreciated.
The standards work of the Audio Engineering Society has been vital to the advancement of the audio industry. Numerous standards in development are driving an expansion of the AES standards operation. That necessitates an expanded base of funding. Unlike other technical societies with standards programs the AES does not charge participation fees. The Society believes that a completely open process ultimately produces better and more widely accepted standards. Consequently other sources of revenue are required.
Standards Sustainers provide critical funding for this effort. Besides enabling the development of standards that underlie fundamental technology in the audio industry, the program offers participants significant marketing and public relations exposure. The Audio Engineering Society is a 501(c)(3) nonprofit organization and 100% of the contribution is tax deductible to the fullest extent of the law.
Donors may contribute at three different levels; a $1,000 basic level, $2,000 Silver level, or the $5,000 Gold level. Details on participating in the Standards Sustainer program may be found on the AES Standards web site.

For some years now, audio signals, both analog and digital, have been transmitted over hardware created for the Ethernet connection protocol, using quad twisted pair (QTP) cabling and “RJ45” connectors. This proposal calls for standardization of the “RJ45” connector pin-out, including channel order, pair color and polarities, and as these correspond to existing audio industry connectors including XLR, 25 pin DSUB and TRS. Other considerations include wiring recommendations, system caveats, and issues arising from operation in the presence of IP network cabling.
SC-05-02 has begun developing a draft standard on this topic. All interested parties are encouraged to join SC-05-02 and participate.

The AGOTTVS group has requested that the AES Standards Committee consider elevation of TD1006: Loudness Guidelines for OTT and OVD Content (Oct 2017) to an AES Standard, Recommended Practice.
This work has been assigned to the Task Group SC-02-12-P led by Jim Starzynski. The new document scope is:
This AES document addresses OTT and OVD Loudness challenges by leveraging already established Over-the-Air Television practices, providing new guidelines focused on the Loudness and Content Dynamic Range for connected set-top and mobile devices. When followed, these guidelines will:
· Provide consistent Loudness across different Programs, service providers and advertising Content
· Provide appropriate playback Loudness Range for different devices and listening conditions
· Prevent excessive Peak Limiting or other processing from degrading the audio quality
· Preserve the artistic intent of wide Content Dynamic Range (movies, drama, live music)
· Improve the listening experience
Interested parties are invited to download the original Technical Council document, review it and send their comments to the Task Group chair. Interested individuals are also encouraged to participate in the groups work.
