The agenda and the report of the previous meeting, 2005-05-29, were accepted as written.
We discussed whether MIDI latency measurements should be included or not.
We discussed whether channels that you are not in use should be muted, including MIDI and PC speaker channels.
We discussed loudspeakers, fan and disk drive noise and electrical noise. People who are interested in working on acoustic fan noise, hard disk drive noise, please send email to the reflector. There was previously a project in SC-04-01 for acoustic noise from PCs. Harris and the secretariat will investigate a new project within SC-04-01. J. Johnson will come up with some names of potential contributors from PC manufacturers.
Sample Rate Converters - an additional test for SRC quality is needed.
W. Jones will champion the work on the next revision of AES6-id. This work will start immediately.
AES17-R: Review of AES17-1998 (r2004): AES standard method for digital audio equipment - Measurement of digital audio equipment
I. Dennis stated that only one person, M. Poimboeuf, had signed up to help with the revision work. Kite also volunteered to help. Dennis will organise the topics between Ian, Thomas, and Michael. Goal is a PTD document before Christmas 2005
61606-3 "Audio and audiovisual equipment - Digital audio parts - Basic measurements methods of audio characteristics � Part 3: Professional use"
Will reach CDV now. The next meeting will be at the AES Convention in Paris, 2006-05. Standard is expected to be published in April 2007.
AES-X118 : ITU-R study group 6 liaison
This project embraces two issues, loudness measurement and peak measurement. Input on peak measurement is requested by the ITU group for their meeting on Monday. They want to complete their document by March 2006. Preliminary draft will be posted to the document site. [see also AES-X141, below]
AES-X151: Jitter performance specification
No progress to report.
AES-X141: Accurate measurement and indication of peak signal levels to avoid
overload of digital media
A number of topics were discussed. It was felt that:
Mr. Okamoto introduced his (NHK) peak level meter. The need for oversampling was discussed.
The next meeting will be scheduled in conjunction with the AES 120th Convention in Paris, France, 2006-05.
