Liaisons:
Now that the AES31-2 BWF standard has been augmented by the latest ammendment to cover file sizes greater than 4 GB, it was felt that we should consider offering the combined standard to IEC to make an international standard. To be progresed as soon as possible by the secretariat.
New Projects:
Holzinger offered a draft of a proposed new chunk, to replace or extemd the current EBU Cue chunk in a BWF file. This would use 64-bit addresses to provide markers into large audio files, both PCM and MPEG-coded. This draft is at an early stage and will be discussed in EBU P/AGA on Monday. Holzinger will post a copy of the draft proposal to the group document site.
New business:
There was no new business
The next meeting will be scheduled in conjunction with the AES 125th Convention in New York, NY., US., 2009-10.
