Open Projects

AES31-2-R Review of AES31-2-2012 Audio-file transfer and exchange - Part 2: File Format for Transferring Digital Audio Data Between Systems of Different Type and Manufacture
This standard is due for review under our 5-year rule. It may be useful to adopt some features of IEC 62942, currently in draft. However the changes in IEC 62942 are expected to be entirely compatible with the current AES standard and so, if there is no proposal for change by the meeting in October 2017, the meeting proposes to reaffirm AES31-2.

AES69-R Review of AES69-2015: AES standard for file exchange - Spatial acoustic data file format
The chair understands from Markus Noisternig that AES69 is being well received in the user community, including the W3C Audio Working Group which supports AES69 in its Web Audio API. The chair also understands that there is an intent to revise and update AES69 in the near future, and a proposal and draft is awaited.

AES31-3-R Review of AES31-3-2008, AES standard for network and file transfer of audio - Audio-file transfer and exchange - Part 3: Simple project interchange. including maintenance of annex F.
Brooks Harris raised the issue in video description using some format compatible with AES31-3. In particular he envisioned adapting the time-Code Format (TCF) described in AES31-3 for video applications. The meeting felt that, although this group could not write a video extension of the standard, we would be happy to support another body that wished to do this.

Development Projects

AES-X236 - IEC 62942 liaison, IEC 62942 liaison, Broadcast Wave Format file
This project has stalled in IEC because of the unavailability of the project leader over the past year. This is soon to be resolved and the project is expected to progress during this year.


No new liaison information

New projects

No new projects were proposed.

New business

The chair announced that he will be retiring at the end of this month for health reasons, and that this working group needed a new chair. It is expected that, if a new chair cannot be found by the time of the October meeting, its projects will be reassigned to an appropriate alternative working group.

The next meeting will be scheduled in conjunction with the AES 143rd Convention in New York, 18 to 21 October, 2017.
