SC-02-08 meeting, New York, 2011-10
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 New York, 2011-10-20
The meeting was convened by chair M. Yonge.
The agenda and the report of previous meeting, held in London, 2011-05-13, were approved as written.
AES31-1-R: Review of AES31-1-2001 (r2006): AES standard for network and file transfer of audio - Audio-file transfer and exchange - Part 1: Disk format
Project scope: This document defines a disk format specification to maintain compatibility with as wide a user base as possible to facilitate audio-file transfer and exchange between differing systems. The document does not describe a complete disk format but provides enough information to choose a proprietary system that will maintain compatibility.
This document was reaffirmed recently. No further action was requested or required.
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
Project scope: This standard defines a file format for interchanging audio data between compliant equipment. It is primarily intended for audio applications in professional recording, production, post production, and archiving.
This document still needs to be revised to incorporate the recent amendment and EBU loudness metadata.
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.
Scope: This standard provides a convention for expressing edit data in text form in a manner that enables simple and accurate computer parsing while retaining human readability. It also describes a method for expressing time-code information in character notation. It supports common professional audio sampling frequencies, video frame rates, and film framing. This document addresses the core need of the AES31 series of standards in providing a simple but extensible system for passing audio material between systems.
No action was requested or required. Noted that a project to produce an XML-compliant version of this standard is being considered as a metadata project in the newly-formed SC-07-01.
AES-21id-R: Review of AES-21id-2011, AES Information Document for audio-file transfer and exchange - Screen-less navigation for high-resolution audio on Blu-ray Disc
Project scope: This information document recommends a method for authoring a BD ROM to enable playback in consumer systems without a video screen, and to provide simple track selection from the remote control.
No action was requested or required.
No new liaison matters.
No new projects
The chair suggested that when the current work has been completed, there seemed little purpose in keeping this group open. Future work on digital storage will most likely involve higher-level issues that would best be handled in a new forum.
If appropriate, the next meeting will be scheduled in conjunction with the AES 132nd Convention to be held in Budapest, Hungary, in April 2012.
