Intelligent Loudness Measurement and Control

In this presentation, we describe loudness measurement techniques that improve accuracy, usability, and consistency relative to previous techniques while considering the (and often overlooked) internal gain structure of digital STBs. Accuracy in this application is determined by correlation to listener opinion, with the particular goal of minimizing annoyance resulting from level mismatch. Usability is improved by minimizing the interaction required by the user. Consistency is achieved by minimizing the amount of meter interpretation required.
