Loudness metering and loudness normalisation signify
a true audio levelling revolution (see Fig. 1). Furthermore,
this loudness-levelling paradigm affects all
stages of an audio broadcast signal, from acquisition to
distribution and transmission. Thus, the ultimate goal is
to harmonise audio loudness levels within broadcast
channels as well as between channels to achieve an equal universal loudness level for the benefit of
the listeners. To be clear: the loudness level can (and should!) still vary according to artistic and tech
