Areas of Concentration
AES TC-AC is the Audio Engineering Society’s Technical Committee on Audio for Cinema.
Reporting to the AES Technical Council (TCL), the primary focus of TC-AC is on developing technical publications, paper sessions, tutorials, workshops and conferences in areas across the complete motion-picture audio supply chain from production through to cinematic exhibition.
TC-AC’s membership is drawn from a wide set of disciplines representing many key stakeholders of the motion-picture industry and is well placed to act as a hub for liaison, discussion, education, and coordination where necessary on topics and issues that impact the global industry as a whole.
New members are always welcome.
Current Areas Of Work
- Cinema Loudness:
Following the initial conclusions of much expert debate and the results of a number of surveys, AES TC-AC is currently bringing together work-in-progress straw-man presentation document that aims to define the problem of inappropriate loudness in cinema with the view to canvas input from key stakeholders and obtain buy-in on what the most effective step-by-step remedies might be in.
- Quarterly Plenary Meetings:
We meet for 90 minutes on the 2nd Thursday of the first month of each quarter (January, April, July, and October) typically using Zoom.
- Ad-Hoc Meetings:
Additional meetings between quarterly meetings as necessary either as the plenary TC or as ad-hoc task groups.
- In-Person Conference Meetings:
In-Person Conference Meetings may occur in addition to or instead of a quarterly depending upon timing.
