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.

Call for Comment on DRAFT REVISED AES67-xxxx - High-performance streaming audio-over-IP interoperability

The Call for Comment on DRAFT REVISED AES67-xxxx, "AES standard for audio applications of networks - High-performance streaming audio-over-IP interoperability" was published 2023-12-28. 

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.

New Task Group for UWB Hi Res, Low Latency Audio Interface

A new Task Group has been created to develop a new standard for Ultra Wide Band (UWB) high resolution low latency audio interface.  Chaired by Jackie Green, the new group is called SC-02-02-B and is under the Working Group on Digital Audio Interfacing chaired by John Grant.  
 
The new standard will describe the preferred way to implement connection management, assure consistent audio quality, and provide for interoperable audio and feature control sets for the MAC convergence and application layers of UWB devices intended for high-quality audio use.

Provide extensions to IEEE 802.15.4ab standard which defines connection, operating features and command structure in order to provide an interoperable interface between UWB audio capture and playback devices. 

All persons interested in participating in this effort should sign up on the Standards website or contact the Standards Manager.
