About AES Standards

Organisation

Standards are a core activity of the Audio Engineering Society and help to ensure the Society can meet the future demands of the audio industry.

AES Standards - a short history

Standards activity in the AES started shortly after the Society was founded. In the early days, the AES Standards Committee (AESSC) mainly acted as a reporting agency to the membership through the Journal on the activities of IEC TC 29 and audio-related activities of other standards organisations such as EIA, SMPTE, IEEE, and the Acoustical Society of America (ASA). Even though the AES at this time was not producing documents, many AES members contributed to standards through these other organisations. An overview paper, first published in 1982, is available from the Historical Committee.

In 1977, stimulated by the growing need for standards in digital audio, the AES Digital Audio Standards Committee was formed. It was responsible for creating some fundamental standards such as the AES3 digital audio interface - sometimes known as the AES/EBU interface - and standards for sampling frequency and synchronisation which are still in use today. (The AES Historical Committee has documented this period of development.)

In 1980, a full-time secretary was appointed.

In 1984, the procedures of the AESSC were revised to improve the openness and consensus of our due process, modelled on IEC directives and drawing from the examples of the ASA, IEEE and SMPTE.

AES Standards today

The present standards secretary was appointed in 2001. Communications facilities were extensively updated in 2002, including a new Web site with public and private areas, members' registry, plus e-mail reflectors and a secure document exchange facility for each group.

Membership of any AESSC working group is open to all individuals who are materially and directly affected by documents that may be issued under the scope of that working group. Currently, we operate 10 working groups - with over 1300 registered members in total - working in the following fields:

  • Digital audio: Digital audio measurements, interfaces & synchronisation, file exchange, and pro-audio uses of data networks
  • Acoustics: Sound-source modeling, loudspeakers and microphones
  • Interconnections: Connectors, connector usage and EMC practices
  • Metadata for Audio: Metadata sets for audio in computers, networks, and archives

These working groups currently maintain 64 published documents and are working on over 40 new development projects.

Liaisons

Standards work in audio does not exist in isolation. The AESSC enjoys liaisons with a number of organisations, including: IEC, SMPTE, BSI, CEA, EBU, 1394TA, ALMA International (loudspeakers). We also maintain informal liaisons with a variety of other relevant groups.
