Radar Meter inspector
The Radar Meter inspector shows the length of
the analyzed clip or file and the amount of time
that the radar circle represents.
E.g., when analyzing and processing a 45 sec-
ond clip, the inspector would show:
“00:00:45 Stereo Full Circle: 1 min”.
Descriptors
The four pairs of descriptors between the two
Radar Meters show essential loudness-related
values for the source clip or file (once it has been
analyzed) and the processed clip or file (once
you have processed the source file).
Source and target Int
(Program loudness) descriptors
The Int descriptors show the Program Loudness
(or “Integrated Loudness”) for the unprocessed
and the processed clip or file. Its unit is LUFS.
Some vendors and countries use the unit “LKFS”
instead of “LUFS”, but they are identical: An ab-
solute measure of loudness in the digital domain,
where the region around “0” is overly loud and
not relevant for measuring anything but test sig-
nals. Expect readings of broadcast programs in
the range between -28 and -20 LUFS.
Program Loudness is used as a production
guideline and to set loudness metadata in deliv-
ery if so required. For delivery or transmission of
AC3 format, the “Dialnorm” metadata parameter
should reflect Program Loudness. The easiest
way to handle multiple broadcast platforms is
to normalize programs at the station to a certain
value, thereby being able to take advantage of
the normalization benefits across platforms, at
the same time enabling static metadata.
