Projects assigned to this group but not mentioned here had no action requested or required - see for details.

Open Projects:

AES-X120 Liaison with International Association of Sound and Audiovisual Archives IASA
The cooperation was confirmed. It was discussed, that our working group should focus on parts from the music industry /production side, as this is something not covered within IASA.

Proposal of a new technical document/standard hosted by AES and in cooperation with IASA was discussed.

Possible forms of cooperation: decoupling this chapter as a joint publication.


Nadja reported on the last meetings with the AES SC-03-12 Working Group on Forensic Audio about the handling and storage of sound recordings. The group did not express actual urgent needs concerning their X253 Collection Guidelines for Forensic Audio, as they have to consolidate their work first; meetings will be attended by members and the chair of our group, to keep in discussion about their needs.

We should coordinate with the SC-02-01 Digital Measurement Standards group on project AES-X217.

Liaison with Metadata group AES SC-07 is also necessary, members and chair of our group to stay in contact.

Toby will provide information about how the cooperation with NARAS on a joint document has worked in practice and formally.

New projects

The group proposed a document on implementation of a recommended workflow for the creation and archiving of digital archival materials from professional audio production formats, such as:

  • Archiving discussion and decision finding: when is it necessary/ makes sense to archive the production format?
  • Multichannel - multitrack
  • File naming, Multitrack tape ingest
  • Archiving assets vs archiving a mix (processing, fader moves, etc.)
  • Born digital production assets (raw version and version encoding all processing decisions)
  • Quadraphonic formats (tape and disc)
  • Noise reduction systems
  • Dolby decoding ( is working on software for this)
  • Surround
  • Immersive
  • Ambisonics
  • Related metadata issues (AES metadata standards group - referencing)
Further discussion points:
  • Persons to involve: George Massenburg, Brian Hoffa, Michael Romanovski, representatives from the industry (Dolby etc)
  • Establish a routine to archive the document on the AES server after every meeting; document template available on the AES Standards site. Documents should be in open document format for easy sharing.
  • The group should start bi-weekly meetings, Tuesday is preferred.

    New business

    No new business was raised.

    The next meeting will be scheduled in conjunction with the AES 152nd Convention, to be held online in May 2022.
