The agenda and the report of the previous meeting were agreed as written.
AES17-R Measurement of digital audio equipment
I. Dennis has posted a document which discusses potential revisions to AES17-1998. He discussed some of the issues mentioned in the document.
AES-X102 Liaison with IEC PT 61606
A working draft of 61606-4, professional audio measurements, was presented at the previous IEC meeting. The next meeting is scheduled for later today, please attend if you are interested.
AES-X118 ITU-R study group 6 liaison
There has been some activity on reflector. Keyhl is not sure of the current status. Just monitoring activity today.
AES-X151 Jitter performance specification
An AES-formatted PTD of this Information Document has been posted. It is intended to propose this as a PWD by end of August. Travis will post an updated version. The target is to propose this document as a PCFC before the next meeting.
The chair thanked Travis and Wolfson for their contribution.
AES-X141 Accurate measurement and indication of peak signal levels to avoid overload of digital media.
The ITU meeting in October 2004 was cancelled. Keyhl felt that more detailed parameters for the measurement need to be defined.
The meeting was reminded that C. Todd's comment from the previous meeting, we should focus on measure peak value in the current stream and not to try to predict the behaviour of downstream devices.
Dennis will send some references about upsampling rate ratio affect on measurement accuracy, with help from Travis.
An updated report is needed before the next ITU meeting in September 2005. Keyhl will make this happen, with help from T. Holm Hansen.
The next meeting will be scheduled in conjunction with the AES 119th Convention to be held in New York, 2005-10.
