Sound for Digital Cinema and Television

Forum:    Committee Discussion Forum


Your TC is now planning a terrific program for the Los Angeles AES Convention in October.

One of the planned workshops is the "Superstars of Production Sound Recording". Perhaps one of the most important technical crafts in all of filmmaking, production sound (often known as the "black box" department) is responsible for capture of original dialog in difficult environments. Some of the best in the field will be getting together for the first time at AES 137!

Stay tuned!

Areas of Concentration

The loudness subcommittee is making terrific progress, and will shortly be finalizing a draft for Standards action. Stay tuned!

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.

Committee chair Ben Kok has asked that members read and comment on a submitted "starting point" document on the Nordtest Method of Calibrating PA Systems. This document is available from the technical library below. Please download this document and take the time to comment on sections of this method prior to the next meeting cycle at AES 137 in October.

Standards work has been proposed to develop systems to educate the sound production community in evaluating overall sound levels being re-recorded for films, along with tools that can be used by cinema operators to protect their audiences from overly-loud movies.
