The input thumbnail meters are the same for EBU and ITU modes. The major difference
is the large Integrated Measurement meter which shows loudness *relative* to -23LUFS
(LKFS) and the scale is in Loudness Units (LU). A reading of 0 shows that the input audio
matches the target.
The bargraphs show measurements with fixed integrations: the top is Momentary with a
400msec integration, the middle is Short term with a 3-second integration, and the bottom
is Integrated with an infinite integration and the relative gate applied. This meter is simply
a graphical indication of the large numerical readout in the top right.
3.2.1 Display Colors
You will notice that in all modes, the meters are very colorful. In addition to being nice to
stare at while listening to some classic Pink Floyd, there is a method to the madness. The
color gives a running indication of loudness with respect to the user-adjustable Target lev-
el, and the variation in color depicts the so-called loudness “Comfort Zone” which is about
15dB wide.
