Abstract(s)
The recent loudness measurement recommendations by the ITU and the EBU have gained widespread
recognition in the broadcast community. The material it deals with is usually full-range mastered audio
content, and its applicability to multitrack material is not yet clear. In the present work we investigate
how well the evaluated perception of single track loudness agrees with the measured value as de ned by
ITU-R BS.1770. We analyze the underlying features that may be the cause for this disparity and propose
some parameter alterations that might yield better results for multitrack material with minimal modi cation
to their rating of broadcast content. The best parameter sets are then evaluated by a panel of experts in
terms of how well they produce an equal-loudness multitrack mix, and are shown to be signi cantly more
successful.
