Gain Center parameter
When you have set the Format Convert param-
eter on the Loudness Wizard’s Main page to
Downmix, the Gain Center parameter can be
used to apply a static gain to the Center chan-
nel before delay, loudness control and true-peak
limiting.
If the processed input signal is already in stereo,
this parameter has no effect.
The default for the Gain Center parameter is
-3 dB, which corresponds to standard downmix
in AC3 decoders. Because the algorithm has a
high internal headroom, there is no overload risk
if the Gain Center parameter is set to 0 dB (or
even positive gain), thereby putting emphasis to
center channel content such as dialog.
Gain Surround parameter
When you have set the Format Convert param-
eter on the Loudness Wizard’s Main page to
Downmix, the Gain Surround parameter can be
used to apply a static gain to the surround chan-
nels before delay, loudness control and true-
peak limiting.
If the processed input signal is already in stereo,
this parameter has no effect.
The default is -6 dB, which corresponds to stan-
dard downmix in AC3 decoders. Because the
algorithm has a high internal headroom, there is
no risk of overload if the parameter is set to 0 dB
(or even positive gain), thereby putting emphasis
to surround channel content such as audience
and room sound.
