STIPA verification test signals now available for download

IEC-60268-16 rev. 5 describes test signals in Annexes A and C that are intended to be used to verify STIPA implementations. If you are implementing STIPA in software or firmware, we recommend that you closely study the standard (including Annexes A and C) and take guidance on verification requirements that are given there. A summary of the test signals, and how these are to be used, are given in the IEC-60268-16 Test Signal description that can be downloaded from the AES Standards web site.

AES-R20-2021, AES Standards Report - AES67 beyond the LAN has been published

 

AES67 has made low-latency, synchronized, and uncompressed audio delivery commonplace on local area networks (LANs). As the need to provide two-way interaction between multiple sites rises, there is a desire to extend AES67 solutions into Wide Area Networks (WAN) and datacenters. This report examines the requirements and challenges when AES67 is extended beyond LAN environments. After describing the operational environments and associated constraints in detail, this report will address timing, transport and data reliability in the context of WAN and cloud. The report shows that none of the discussed environments is associated with a specific single problem, but instead, there are a number of smaller technical factors that interact and need to be addressed. While this study indicates that bit-precise transmission, synchronization and timing alignment is reasonably achievable, very low latencies, use of multicast, and 100% reliable reception remain challenging or impossible. Field experience annexes included in this report correlate well with the theoretical expectations based on this study. Robustness of AES67 is confirmed by its success on WAN production facilities and long-distance deployments. It brings generally better audio quality, latency performance and routing flexibility, compared to point-to-point transport based on lossy compression.

 

This document was developed in the SC-02-12-M task group on AES67 development under the leadership of Nicolas Sturmel.

Standards Sustainer program renews for 2021-2022

The AES Standards Sustainer program is a way for companies to financially support the AES Standards Committee activities. 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 we depend on other sources of revenue.

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, including new projects in networked audio, forensic audio, and the restarting of our working group on Digital Library and Archive Systems.  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.

Renewal invoices will be sent to existing Standards Sustainers June 1st.  Other interested parties are encouraged to become Standards Sustainers as well.

Fred Morgenstern appointed new chair of SC-05-02

Fred Morgenstern has taken over as chair of SC-05-02.  Anthony Kuzub will continue to serve as vice-chair.  Fred is a long time AES member and is a Product Director for Neutrik.  The group is currently working on a review of AES59 – Audio application of 25 way D-type connectors in balanced circuits, updating it with respect to grounding and EMI.  The groups last project was AES42 which standardized the application of RJ45-type connectors for professional audio applications.  


If you have an interest in connectors for audio and ancillary applications please join the group using the link below.   Once you have joined the group you will have access to the groups documents and relevant supporting materials.
