Accuracy of ITU-R BS.1770 Algorithm in Evaluating Multitrack Material
Loudness measurement that is computationally efficient and applicable on digital material disregarding listening level is a very important feature for automatic mixing. Recent work in broadcast specifications of loudness (ITU-R BS.1770) deserved broad acceptance and seems a likely candidate for extension to multitrack material, though the original design did not bear in mind this kind of development. Some empirical observations have suggested that certain types of individual source materials are not evaluated properly by the ITU’s algorithm. In this paper a subjective test is presented that tries to shed some light on the subject.
