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.

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.  

http://www.aes.org/standards/comments/cfc-draft-rev-aes70-3-xxxx-230928.cfm
 
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. 
 
Calls for Comment are open for six weeks from the date of publication.

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.  

http://www.aes.org/standards/comments/cfc-draft-rev-aes70-2-xxxx-230928.cfm  
 
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..
 
Calls for Comment are open for six weeks from the date of publication.

Call for Comment on DRAFT REVISED AES70-1-xxxx - Open Control Architecture - Part 1: Framework

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.  

http://www.aes.org/standards/comments/cfc-draft-rev-aes70-1-xxxx-230928.cfm
 
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. 
 
Calls for Comment are open for six weeks from the date of publication.

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.
