AES Technical Committee
Sound for Digital Cinema and Television
Chair: Julius Newell (Send Email) Forum: Committee Discussion Forum
With the 57th Conference on the Future of Audio in Entertainment now a happy memory, our attention is turned to the 138th Convention in Warsaw, Poland.
We are planning the usual array of workshops for this European Convention, the first visit by the AES to Warsaw.
The calendar of events is available here: http://www.aes.org/events/138/calendar/calendar.cfm
We are also planning a site visit to the world class Dreamsound Studios in Warsaw for a Dolby Atmos demo.
We look to seeing everyone there.
Areas of Concentration
The agenda for our next TC meeting has been emailed to all the registered participants of the committee.
The agenda has also been uploaded to the technical documents folder.
The meeting is scheduled for Friday, 8 May 2015, at 2:00 PM in the TC meeting room at the Sofitel Conference Centre in Warsaw, Poland.
Current Areas Of Work
Standards work to produce a modern, workable, and accurate procedure to test and calibrate a sound system is underway as SC-04-08.
The SMPTE has finished their long-awaited B-Chain Study Group report that documents the current performance of both theatres and dubbing rooms in Los Angeles. This will be an additional reference to the poor situation we find ourselves as documented in the IOA presentation by Philip Newell, et. al. (Available in our document library)
NEW TASK GROUP ANNOUNCEMENT
At the recently concluded 57th Conference in Hollywood, several items were identified as action items by the Conference.
One of these is the issue of bass management.
The SMPTE B-Chain Report issued last October identified bass and subbass as a major area of discrepancy between both the dubbing rooms as well as the cinemas. Additionally, this confusion about audio in the bass region has spilled over into home theater and music production. This is what happens when no Standards exist.
I'd like to announce the formation of a task group as part of SDCTV to look at the issue, and provide recommendations that may be the basis of a new AES Standard in this area.
I expect the group to be activated on the website shortly, and a chair to this group will be appointed prior to the Warsaw Convention.
I look forward to the participation of a cross-section of entertainment audio production experts so that we can handle this issue in a comprehensive manner.
