AES Standards to remove culturally insensitive terms

The AES Standards Committee is starting a project to update terminology in AES Standards which may be culturally insensitive.  Use of the terms "master" and "slave" are specifically being examined, but others may be as well.  This is a general issue for all products, systems, architectures, and standards that have used those terms heretofore.

To avoid confusion it is also important that replacement terms be consistent with similar efforts being undertaken in the IEEE and SMPTE.  The AESSC has a strong liaison relationship with SMPTE and is looking to form one with the IEEE specifically to assist with this effort.

The committee hopes that in due course it can arrive at a uniform replacement that will work gracefully for the majority of cases, to avoid both opposing extremes:

1. having to develop case-specific solutions for each affected standard;

2. having generic but impossibly awkward terms.

The committee welcomes input on this topic.  Please address all comments and submissions to the Standards Manager.

Standards Sustainer program renews for 2020-2021

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, loudspeaker measurement, and the restarting of our standardization efforts in forensic audio.  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 went out to existing Standards Sustainers earlier this month.  Other interested parties are encouraged to become Standards Sustainers as well.

Spring 2020 AES Standards meetings held online

In a first for the AES, the spring Standards meetings were held entirely online May 26 – 29. Meetings have been accesible online during previous conventions, but this is the first time there has not been an in-person component Twelve working groups met over the 4 days.  Meeting length ranged from 30 to 90 minutes and attendance varied from 7 to 25 people.  The meetings were followed by a Plenary meeting at which the chairs of each working group summarized the activity within their group. 

Meeting reports will be posted on the AES Standards web site as they become available.

Spring 2020 AES Standards Meeting Schedule published

The Vienna AES Convention in May 2020 has been converted to a virtual format as a consequence of the COVID19 pandemic. Consequently the concurrent AES Standards meetings will be changing to an online format. 

Since physical attendance is no longer required, the Standards meetings will not be held on the same dates as the online convention. The convention has been delayed, and will now run June 2 - 5, 2020.  Standards meetings will be held the week before the AES convention, to reduce schedule conflicts for attendees. 

Since attendees will no longer all be in the same time zone, as happens with physical meetings, the meeting schedule will be different. Meetings have been limited to 4 hours in any single day to allow meeting times which span the widest number of waking time zones.  Since all active Task Groups hold regular online meetings, usually biweekly, they will not hold special meetings associated with the online convention.

AES60id-2020 AES Information Document for audio metadata - Core audio metadata has been published

AES60id-2020, "AES Information Document for audio metadata - Core audio metadata" was published 0n 2020-04-15.

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).

May 2020 AES Standards meetings will be held online

The Vienna AES  Convention in May 2020 is being converted to a virtual format as a consequence of the COVID19 pandemic.  Consequently the concurrent AES  Standards meetings will be changing to an online format. 

Since physical attendance is no longer required, the Standards meetings will not be held on the same dates as the online convention.  It is likely that they will be held the week after the AES  convention, to reduce schedule conflicts for attendees. 

Since attendees will no longer all be in the same time zone, as happens with physical meetings, the meeting schedule will be changed.  Meetings will be limited to 2 hours in any single day to allow selection of a meeting time which spans the widest number of waking time zones.  This will extend the meetings over more than the usual 4 days.

When a schedule is determined it will be posted on the AES Standards web site in the AES Standards Meetings and Reports web page.  Emails will be sent to all AES Standards Working Group and Task Group members announcing the time for their individual meetings.

New project to revise AES69-2015, Spatial acoustic data file format, in SC-02-08

Working Group SC-02-08, chaired by Piotr Majdak and Markus Noisternig has begun revisions of AES69-2015 AES standard for file exchange - Spatial acoustic data file format. It standardizes a file format to exchange space-related acoustic data in various forms. The format is designed to be scalable to match the available rendering process while being sufficiently flexible to include source materials from different databases. 

Binaural listening is growing fast, because of growing sales in smartphones, tablets and other individual entertainment systems. The lack of a standard for the exchange of head-related transfer functions (HRTF) means each company keeps its binaural capture and rendering algorithms private. 3D audio is arising, and binaural listening could be the very first 3D audio vector with sufficient fidelity of HRTF. 

The use of convolution-based reverberation processors in 3D virtual audio environments has grown with the increase in available computing power. Convolution-based reverberators guarantee for an authentic and natural listening experience, but also depend on the acoustic quality of the applied directional room impulse response (DRIR).

With a standardized file format for HRTF and DRIR data, each company could contribute its best algorithms, providing good personalized capture and/or rendering, allowing the consumer to choose its best combination of technologies for the best quality of experience.
