New Standards Sustainers for 2024

Metoree, Lenbrook Media Group, Lautsprecher Teufel GmbH, and Hangzhou Hikvision Digital Technology CO.,LTD have joined the AES Standards Sustainer program at the basic level. The generosity and support of all four 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 nonprofit organization and 100% of the contribution is tax deductible to the fullest extent of the law.

In the past year, Standards Sustainer's generous contributions helped fund ongoing Standards activities and our liaison relationships with other societies.  It also allowed the AES to launch new standards development projects, and continue work on existing projects.  We could not have accomplished these things without that support.

Besides enabling the development of standards that underlie fundamental technology in the audio industry, the program offers significant exposure and valuable marketing / public relations avenues.

Information on the program is available here

Get Involved In AES Standards

 

Standards are a core activity of the Audio Engineering Society and help to ensure the Society can meet the future demands of the audio industry.  AES Standards are developed by members of the audio industry, with guidance from the AES Standards Manager.  Broad participation across the industry is essential for these standards to be both authoritative and useful.  If you have skills and knowledge to share, please get involved!

Membership of any AESSC working group is open to all individuals. AES membership is not required.  Currently, we operate 13 working groups - with approximately 1000 registered members - working in the following fields:

These working groups currently maintain 84 published standards and information documents, have issued 16 reports and are working on over 12 new development projects.

AES67-2023, "AES standard for audio applications of networks - High-performance streaming audio-over-IP interoperability" has been published

High-performance media networks support professional quality audio (16 bit, 44,1 kHz and higher) with low latencies (less than 10 ms) compatible with live sound reinforcement. The level of network performance needed to meet these requirements is typically available on wired local-area networks and is achievable on enterprise-scale networks, but is generally not available on wide-area networks or the public internet. 

The most recent generation of these media networks use a diversity of proprietary and standard protocols. Despite a common basis in Internet Protocol, the systems do not interoperate. 

This standard provides specific recommendations for interoperability. The standard focuses on defining how existing protocols are used to create an interoperable system. No new protocols have been developed to achieve this.
 
The standard is expected to be useful for commercial audio applications including fixed and touring live sound reinforcement. It is also expected to be useful for distribution within broadcast, music production and post-production facilities.
 
This standard depends on established network protocols (see clause 2). These protocols can include additional options that are not required by this standard. Robust implementations of AES67 will tolerate these additional options.

Any behavior details not described in the main part of this standard are in some cases clarified in Annex G (PICS), by means of the respective evaluation criteria.

Call for Comment on DRAFT REVISED AES63-xxxx - AES standard for interconnections - Data connector in an XLR connector shell

The Call for Comment on DRAFT REVISED AES63-xxxx - AES standard for interconnections - Data connector in an XLR connector shell was published on 2024-02-23.

Commonly used modular connectors are widely used, but are fragile in demanding installations, where a broken connection can affect the application critically. This is not important in many applications, such as structured data cabling for use with computer networks, or simple interconnect cabling and patching using Category 5 (or better) data cable.  However, in professional audio applications, a broken connection can affect the application critically. A standard ruggedized fitting will promote system security in these applications. This document specifies a ruggedized data connector that is compatible with 8-position 8-contact (8P8C) modular connectors, commonly (though inaccurately) called RJ-45 connectors, with regard to mechanical aspects for proper mating and locking.

New project - AES-X261: Polarity and pin configuration for linear balanced audio PCB connectors

This project will define the number of pins used for each channel and the pin configuration for connecting +, -, signal conductors and cable shield for linear PCB (aka euroblock) connectors.

The widespread adoption of PCB (aka euroblock) connectors without a pin configuration has led to many different varieties causing wiring mistakes, compromised noisy immunity, and added time to installs.  Much of the industry has gravitated toward a (+/-/shield) configuration but it should be standardized.  Furthermore, there are practical and technical considerations to avoid a 5-pin configuration for channel pairs.

The development will take place in Working Group SC-05-02, chaired by Fred Morgenstern.  Interested parties are encouraged to join the group and contribute.  The memberships of AESSC working groups are open to all directly and materially affected individuals.  AES membership, although strongly encouraged, is not required.

AES70-2023 AES standard for audio applications of networks - Open Control Architecture - has been published

AES70 is a suite of standards for control and monitoring of devices in professional media networks. AES70 does not specify a media transport scheme. Rather, it is designed to operate with media transport schemes such as the one specified by AES67.

AES70's intended range of use spans networks of all sizes. This includes mission-critical applications, high-security applications, IP and non-IP networks, and local and wide-area applications. AES70 can control real or virtual devices located on premises or hosted by cloud services. AES70 consumes little computing power and uses network bandwidth lightly.

AES70 is based on the Open Control Architecture (OCA), originally developed by the OCA Alliance.
