the Output level is close to the Target Level, gain
changes are relatively slow.
The Average Rate offsets all time constants to be
faster or slower. Values below 1 dB/Sec produc-
es a gain change gating effect when the Output
level is already in the target zone, while values
above 4 dB/Sec will add density to sound.
Slow Window
Range: 0 to 20 dB
The slow window is the area around the set Tar-
get Level.
Within the slow window, the Loudness is only
gently controlled. When the signal exceeds the
limits of the Slow Window the Loudness is treat-
ed more radically. Depending on the set Average
Rate and Ratio.
Loudness Measure
Select between ITU BS.1770 and ITU BS.1770-2
The loudness model employed in the Loudness
section is based on Leq(K) weighting. This pa-
rameter selects if programs should generally
aim at Target values measured without gating,
like in the original ITU standard (BS.1770 setting),
or measured with gating, like in the current ITU
standard (BS.1770-2 setting).
Multiband parameters
For the Mid filter select between filter types:
Parametric and Notch.
Parametric Filter – Broad type
Shelving Filter
Notch Filter – Narrow Type
