RMS of the input plus peaks that are
12dB higher than the current RMS value.
The Root Mean Square has been found
to correspond very well to our perception
of level with total mixes and smoothly
changing single sources. However, with
more percussive types of materials you
would go for a more peak oriented
control of the compressor with a lower
dB setting or PEAK only.
PAGE 5 - LIMITER:
L-THRSH -12 dB - 0.0 dB Limiter threshold. The limiter is meant
to be a brickwall type to prevent
unintentional compressor overshoots
from causing full-scale overloads. Its
threshold is thus referring to digital full-
scale as is the overall softclipper
function.
The '0dB ref', the BND-LEV and the
OUT-LEV parameters all affect 'how
hard' you hit the limiter. A normal
setting for CD master processing would
be a few dBs down, whereas an EBU
broadcaster would set L-THRESH as
low as -12dB (according to the R68
recommendations.)
