SC-02-08 meeting, Warsaw, 2015-05

Report of the meeting of the SC-02-08 Working Group on audio file transfer and exchange of the SC-02 Subcommittee on Digital Audio, held in Warsaw, Poland, 2015-05-07

The meeting was convened by chair M. Yonge.

The agenda were approved as written. The group did not meet in in Los Angeles, 2014-10, and so there was no report.

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

Open Projects

AES31-2-R: Review of AES31-2-2006: Audio-file transfer and exchange - Part 2: File Format for Transferring Digital Audio Data Between Systems of Different Type and Manufacture
No action was requested or required.

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.

No action was requested or required.

AES69-R Review of AES69-2015, AES standard for file exchange - Spatial acoustic data file format
The draft developed in this group as AES-X212 was finally published as AES69-2015 in March of this year following due process. No further action was requested or required.

Development Projects

AES-X236 - IEC 62942 liaison, BWF
A new project has been created to manage liaison activities between AES31-2 in this group and IEC 62942 in TC100.

In discussion, it has been agreed that a universal BWFF shall carry the essential data elements described in AES31-2. It will also support an option to include a "ubxt" chunk containing human-readable metadata in multi-byte character format that in turn will support all international character sets. The 'ubxt' chunk will always be an addition to a conventional BWFF and 'bext' chunk, and not a replacement to assure universal compatibility.


No new liaison information

The next meeting will be scheduled in conjunction with the AES 139th Convention in New York, NY., US., 29 October to 1 November, 2015.
