The Call for Comment on DRAFT REVISED AES70-1-xxxx, "AES standard for audio applications of networks - Open Control Architecture - Part 1: Framework" was published 2023-09-28.

AES70 defines a scalable control-protocol architecture for the control and monitoring of professional media networks. AES70 addresses device control and monitoring only; it does not define standards for transporting streaming media or for describing media content.

This Part 1 describes the models and mechanisms of the AES70 Open Control Architecture. These models and mechanisms together form the AES70 Framework. This document should be read in conjunction with Part 2, Class Structure and Part 3, TCP/IP communications protocol.

Call for Comment on DRAFT REVISED AES70-2-xxxx - Open Control Architecture - Part 2: Class structure

The Call for Comment on DRAFT REVISED AES70-2-xxxx, "AES standard for audio applications of networks - Open Control Architecture - Part 2: Class structure" was published 2023-09-28.

AES70 defines a scalable control-protocol architecture for professional media networks. AES70 addresses device control and monitoring only; it does not define standards for streaming media transport.

AES70 is divided into a number of separate parts. This Part 2 specifies the control class structure that defines the control and monitoring functional capabilities of the standard and should be read in conjunction with Part 1, Framework..

Call for Comment on DRAFT REVISED AES70-3-xxxx - Open Control Architecture - Part 3: Protocol for TCP/IP Networks

The Call for Comment on DRAFT AES70-3-xxxx, "AES standard for audio applications of networks - Open Control Architecture - Part 3: Protocol for TCP/IP Networks" was published 2023-09-28.

AES70 defines a scalable control-protocol architecture for professional media networks. AES70 addresses device control and monitoring only; it does not define standards for streaming media transport.

AES70 is divided into a number of separate parts. This Part 3 specifies a protocol implementation for TCP/IP networks. It should be read in conjunction with Part 1, Framework, and Part 2, Class Tree.

New project to specify the criteria for the authentication of digital audio recordings

The AES SC-03-12 Working Group on Forensic Audio, chaired by Marisa Dery, has started a new project to specify the criteria for the authentication of digital audio recordings.

The X259 project will formulate a standard scientific procedure for the authentication of digital audio recordings intended to be offered as evidence or otherwise utilized in civil, criminal, or other fact finding proceedings.

AES has produced AES43 which sets procedures for authentication of analog audio recordings but the norm for current cases has been to use digital media. With cell phones, ring cameras and other recording devices becoming the standard for recording audio it is imperative to produce a similar document for digital recordings.

The Working Group is soliciting input and participation by all interested parties. If you would like to participate, sign up using the link below.

Fall 2023 AES Standards Meeting schedule announced

The fall AES Standards Working Group meetings will be held the week of October 9 through 13. As has been the case for several years the meetings will be held online using Zoom. Details and a complete schedule are available on the AES Standards website. Unlike recent years the AES Standards Plenary meeting will be held in person during the AES Convention in New York. The exact date and time of the Plenary meeting will be published in the convention schedule.

AES66-2012: AES standard for professional audio equipment - Application of connectors - Miniature XLR-type polarity and gender

AES77-2023 AES Recommended Practice Loudness Guidelines for Internet Audio Streaming and On-Demand Distribution has been published

This AES Recommended Practice (RP) provides comprehensive recommendations establishing and implementing an effective Distribution Loudness for streaming and on-demand audio file playback. It is intended for use by distributors of Internet audio streams and on-demand audio files.

Implementing these guidelines will provide consistent Loudness and appropriate playback loudness range, will reduce audio quality degradation from excessive limiting, will preserve the original artistic intent, and will improve the listening experience. This document does not recommend Loudness Range (LRA), device target playback loudness or device dynamic range.

New Web page to document AES75-2023 adoption

The AES SC-04-03-A Task Group is creating a webpage on the AES site documenting the adoption of AES75-2023:, AES standard for acoustics – Measuring loudspeaker maximum linear sound levels using noise. It will document the use of AES75 in product and system specifications, product and system evaluation, and list equipment capable of making the measurement.

If you or your firm utilizes AES75 for your own products, provides AES75 measurements as a service to clients, or produces equipment supporting AES75 please contact the Standards Manager to have your information listed on the AES web site.
