New Standards Sustainers

New Standards Sustainers

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.

New project to define a standardized method for transporting metadata associated with audio in an AES67 stream

The SC-02-12-R task group is working on a project to define a standardized method for transporting metadata associated with audio in an AES67 stream. The audio metadata shall be transported in a separate stream that is sent in parallel to AES67 streams rather than part of the AES67 stream. The standard shall define synchronization between the audio metadata transport and the associated AES67 transport. The transmission method shall be low latency and have a level of network performance equivalent to AES67. Within the scope is formatting of the streaming audio metadata for transport. Suggested is an open standards based framework that supports both static and dynamic, time synchronous metadata that is optimized for live workflow applications. The standard shall consider all use cases for metadata associated with AES67, support existing AES audio metadata standards, and be extensible for future metadata requirements. The standard will consider binding between the audio metadata transport and the associated AES67 transport.. 

Since this is a Task Group effort permission of the group chairman is required to participate.  Interested parties should request membership by contacting the Standards Manager

Application of RJ45-type connectors and quad twisted pair cable for audio Interconnections

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.

Call for Comment on DRAFT AES71-xxxx - AES Recommended Practice - Loudness Guidelines for Over the Top Television and Online Video Distribution

The Call for Comment on DRAFT AES71-xxxx, "AES Recommended Practice - Loudness Guidelines for Over the Top Television and Online Video Distribution" was published 2018-03-28.

This AES Recommended Practice (RP) describes the many issues related to online audio Loudness variations.  It provides comprehensive recommendations documenting effective guidelines for managing audio Loudness of soundtracks of television and video content available to consumers by Over-The-Top (OTT) and by Online Video Distributors (OVD).

When followed, these guidelines will provide consistent Loudness, appropriate playback loudness range, reduce audio quality degradation from excessive limiting, preserve the original artistic intent, and improve the listening experience. This document does not provide specific recommendations about target playback loudness or dynamic range.

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 2018-02-14. 

This standard defines an interoperability mode for transport of high-performance audio over networks based on the Internet Protocol. For the purposes of the standard, high-performance audio refers to audio with full bandwidth and low noise. These requirements imply linear PCM coding with a sampling frequency of 44,1 kHz and higher and resolution of 16 bits and higher. High performance also implies a low-latency capability compatible with live sound applications. The standard considers latency performance of 10 milliseconds or less.  This standard provides comprehensive interoperability recommendations in the areas of synchronization, media clock identification, network transport, encoding and streaming, session description and connection management.
 
This revision contains clarifications and minor corrections and adds a Protocol Implementation Conformance Statement (PICS) as Annex G. A new sender keep-alive recommendation, has been added to clause 6.3. Minor clarifications and corrections include a specification of MTU requirements in the presence of allowed (but not recommended) additional information in the RTP header and correcting SDP examples in clause 8.5 to match an erratum issued by the IETF on RFC 7273.

Loudness Guidelines for OTT and OVD Content to become an AES Recommended Practice

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.

AES Call for Comments on Technical Requirements for Media Network Directories and Services has been extended

The Call for Comments on Technical Requirements for Media Network Directories and Directory Related Services has been extended through February 2018.

From this document, and the comments received on it, the AES Task Group on AES-X238, Media network directory architecture will develop a set of requirements for media network directory standards that will work with present and future media networks over a wide range of application domains. Interested parties are encouraged to submit general and specific comments, proposed additions or changes, and responses to the specific questions it poses.

Media network directories are application-layer mechanisms that collect, store and disseminate information about devices, application services, and other elements of media networks. They are used for connection management, network supervision, and other purposes.
 
The standard that will result from this document will be aimed at directory standards that specify:
• Registration, query, and administration protocols;
• Security mechanisms;
• Directory data model;
• Query language and related semantics; and
• Scalability strategies by defining both peer-to-peer and server-supported modes.
 
Although directories are used by connection management mechanisms, such mechanisms are not addressed in this document. In this context, "connection management" means the protocols and processes in a media network by which signal flows are set up, monitored, and taken down.
 
Responses should be submitted by February 15, 2018
