Project to specify a common way to control routing of AVDECC/Milan audio streams launched

AES-X252, a project to specify a common way to control routing of AVDECC/Milan audio streams using an adaptation of the AES70 CM3 feature set, has been started.  It will be developed in SC-02-12-L under the direction of co-chair Morten Lave.

The document will specify a common way to control routing of AVDECC/Milan audio streams using an adaptation of the AES70 CM3 feature set.  The document will also define a programmatic interface between AES70 and AVDECC software drivers that is suitable for implementing the defined adaptation.

The industry will benefit from having one unified layer 3 method of controlling connection management of media streams regardless of the media transport and independent of the protocol layer used for the media transport.

Interested parties may join the SC-02-12-L task group and participate remotely via teleconference and receive updates by email.

Call for Comment on DRAFT AES60id-xxxx - AES Information Document for audio metadata - Core audio metadata

The Call for Comment on DRAFT AES60id-xxxx, "AES Information Document for audio metadata - Core audio metadata" was published 2020-03-03.

This specification addresses the creation, management and preservation of material that can be re-used as originally produced, or may provide input material for new production projects. Material is expected to be exchanged between various organisations or between production facilities in a distributed environment.. 

The core set of metadata presented in this specification is a co-publication of EBU Tech3293-2019 EBUCore, itself an extension to and a refinement of the Dublin Core. EBUCore is a minimum list of attributes characterizing video and / or audio media resources. An XML representation is used as this is the likely method that metadata would be implemented, for example in archive exchange projects using the Open Archive Initiative's Protocol for Metadata Harvesting (OAI-PMH).

1. Registration, query, and administration protocols;

2. Security mechanisms;

3. Directory data model;

4. Query language and related semantics; and

5. Scalability strategies.

This document was developed in the SC-02-12-N task group on AES67 development under the leadership of Jeff Berryman.  The document includes contributions from the OCA Alliance Technical Committee and SMPTE TC34cs.

Project to analyze the AES74 conformance of current media network directory schemes launched

AES-X251, a project to analyze the AES74 conformance of current media network directory schemes, has been started.  It will be developed in SC-02-12-N under the direction of chair Jeff Berryman. 

The task group will survey both standards-based and non-standards-based directory/discovery systems and will report a summary of the results.

The report will inform future directory implementations, hopefully rendering them more powerful, versatile, scalable, and easy to use.  This should lead to increased interoperability of media network products in the long run.

The results will be of use to media network designers and users, and media network equipment manufacturers. Draft copies of the report will be circulated to the proponents of the surveyed directory schemes for comment.

Interested parties may join the SC-02-12-N task group and participate remotely via teleconference and receive updates by email.

IEC 62942:2019 "File format for professional transfer and exchange of digital audio data" published

IEC 62942, "File format for professional transfer and exchange of digital audio data", was published in December 2019. It is primarily intended for audio applications in professional recording, production, post-production, and archiving.  Edition 1 2019-12 is based on and compatible with AES31-2-2019.  It is also compatible with variant specifications including EBU Tech 3285, ITU-R BR.1352-3-2007, and the Japan Post Production Association's BWF-J.

This document contains the specification of the broadcast audio extension chunk and its use with PCM-coded audio data. Basic information on the RIFF format and how it can be extended to other types of audio data is given in Annex E. Details of the PCM WAVE format are also given in Annex A.  An optional extended format, BWF-E, supports 64-bit addressing to permit file sizes greater than 4 GB.  

This is the result of much effort by the SC-02-08 Working Group on Audio-File Transfer and Eschange, led by chair Mark Yonge.

AES Standards SC-03-12 Working Group on Forensic Audio is restarting

The AES Standards Committee has decided to restart its Working Group on Forensic Audio.  The initial project, led by John Hansen of the US NIST OSAC – SPEAKER Committee, is to establish the OSAC SPEAKER “AUDIO COLLECTION GUIDELINES” as a standard.    Now that the Working Group on Forensic Audio has been re-established it may also pursue development of standards in other areas of Forensic Audio.

AES Standards Working Groups meetings are held electronically on a schedule determined by the group and also typically meet physically twice per year at the Society's conventions in the US and Europe. It is also possible to participate in the biannual physical meetings through electronic means.   Much of a groups work is accomplished by email and documents presented to or generated by the group are kept in an online document repository accessible by group members.  There is no fee to be a member of an AES Working Group, nor do you have to be an AES member.

If you would like to participate in, or just monitor progress of, this group please join online or contact the Standards Manager.

Audio Engineering Society Honored with Technology & Engineering Emmy® Award

AES67 standard group in 2013

AES67 standard group in 2013

The National Academy of Television Arts & Sciences (NATAS) has honored AES for “Development of Synchronized multi-channel uncompressed audio transport over IP Networks” in the 71st annual Technology & Engineering Emmy® Awards.  The 71st annual Technical & Engineering Emmy Awards will be presented in a special ceremony at the upcoming NAB Show at the Wynn Encore Hotel and Spa on Sunday, April 19th, 2020, in Las VegasNV

AES67 is an essential protocol that established a standardized language for audio transport, employed every day in the broadcast world and beyond. Its introduction in 2013 fundamentally changed the broadcast audio landscape and paved the way for recent similar developments for video.

The distinction for “Development of Synchronized multi-channel uncompressed audio transport over IP Networks” cites the AES alongside ALC NetworX, Audinate, Kevin Gross, QSC, Telos Alliance and Wheatstone. AES67 compliance allows audio content interoperability between the proprietary IP-based audio networking protocols developed by the Emmy co-winners: RAVENNA, Dante, Q-Sys, Livewire+ and WheatNet-IP. Co-Emmy-winner and AES Fellow Kevin Gross led the AES67 Standards effort as chair of the AES Standards Task Group on AES67 Development and is the chair of the AES Technical Committee on Network Audio Systems. Former AES Standards Manager Mark Yonge, mentored the standard through the development process.  The improvement from audio networking born in the mid-1990s to new IP-based solutions emerged as a simultaneous invention from the honored companies.  While collectively this represented a technical improvement, interoperability was not addressed until the AES initiated the X192 project on audio interoperability.  Steve Church, Rich Zwiebel, Philip Lawo and Andreas Hildebrand, leaders at these companies, understood the potential for an audio networking standard to greatly speed advancement of the technology. 

The Technology & Engineering Emmy Awards are awarded to a living individual, a company, or a scientific or technical organization for developments and/or standardization involved in engineering technologies that either represent so extensive an improvement on existing methods or are so innovative in nature that they materially have affected television. A Committee of highly qualified engineers working in television considers technical developments in the industry and determines which, if any, merit an award.
