Convention Paper

Automatic Long-term Loudness and Dynamics Matching

Authors: Vickers, Earl

AES Convention 111 · Paper 5495 · November 2001

Abstract

Traditional audio level control devices, such as automatic gain controls (AGCs) and compressors, generally have little or no advance knowledge of the dynamic characteristics of the remainder of the current audio program. If such advance knowledge is available (i.e., if audio files can be pre-analyzed), it becomes possible to match desired values of overall loudness and dynamics. We introduce two new measures, "long-term loudness matching level" and "dynamic spread," and present new methods for long-term loudness and dynamics matching.
