bution, and not to process more than necessary
for a certain broadcast platform. Don’t take pride
in being the loudest station, but in being the best
sounding and most consistent one.
For broadcast stations early in the process of
converting production to loudness based crite-
ria, a relatively high Loudness adjustment Ratio
may be initially needed, for instance 1:2, in order
to avoid too much loudness fluctuation during
transmission. Once production adopts loudness
metering, and programs are normalized prior
to transmission, the Ratio control should be re-
laxed and/or the Max Attenuation and Max Gain
should be moved closer to 0.0 dB.
Based on LM6 output measurements, it may be
indicated to raise Target Level over the expected.
While the BS.1770-2 Loudness Measure setting
already helps on the average, a slightly higher
Target may be needed (depending on type of
programming) to get close to the station’s loud-
ness Target.
All loudness adjustment algorithms in DB pro-
cessors feature extreme flexibility. Processing
may be used to only attenuate or to only boost,
and the amount of cut and boost may be restrict-
ed. Furthermore, it’s easy to switch to limiting
only on the fly, or to completely bypass process-
ing, should certain programs have been precise-
ly normalized and controlled already.
