There are no common target LRA values defi ned in the loudness stan-
dards yet. Nevertheless, the three distinct areas „Comfort Zone“ (average
LRA values), „High Range“ (high LRA values) and „Low Range“ (low LRA
values) are used that can help to classify a program with regard to its
LRA measurement and mark it with a distinct color.
The „Magic LRA“ mode available in the LRA instrument uses a scale with
a fi xed centered zero position (corresponding to the target level) where
the LRA bar spreads symmetrically from the 0 position and its length is a
measure of the absolute LRA value.
