Evaluation Criteria for Live Loudness Meters

Authors: Allan, Jon; Berg, Jan

AES Convention 137 · Paper 9175 · October 2014

Abstract

As a response to discrepancies in loudness levels in broadcast, the recommendations of the International Telecommunication Union and the European Broadcasting Union state that audio levels should be regulated based on loudness measurement. These recommendations differ regarding the definition of meter ballistics for live loudness meters, and this paper seeks to identify possible additional information needed to attain a higher conformity between the recommendations. This work suggests that the qualities we seek in a live loudness meter could be more differentiated for different time scales (i.e., momentary and short-term that is defined by two different integration times), and therefore also should be evaluated by different evaluation criteria.
