“The truth is, for me, it’s obvious that 70/80 % of a movie is sound. You don’t realise it because you can’t see it.”

Danny Boyle

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.

Meeting Schedule

  • 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.

Mission Statement

  • Coordinate the development of technical parameters of sound for the cinematic experience, including loudspeaker performance, components for multichannel sound systems, loudness and sub bass loudness-measurement techniques.
  • Coordinate workshops, tutorials, master classes and poster sessions in the field of audio for cinema at AES conventions, conferences and related events. Propose subject matter for technical papers and encourage their creation and dissemination at these events and for the AES Journal.
  • Promote awareness of new creative trends and technical developments that may impact and all aspect of audio for cinema, including direct interface with owners and operators of professional-grade re-recording stages that create theatrical-release soundtracks.
  • Encourage technical communications and education within the myriad of groups in the audio for cinema community.
  • Create enhanced awareness within the larger pro-audio community of the technical and creative challenges faced by the audio for cinema industry.
  • Work closely with SMPTE and other industry groups that are in the audio for cinema arena to coordinate efforts toward common goals, including proposing standards work and facilitating research.
