Delay Unit parameter
Use the Delay Unit parameter to set the display
unit for the Audio Delay and Delay Unit param-
eters.
ms setting
To display the Audio Delay and Max Look-ahead
parameters in milliseconds, set the Delay Unit
parameter to ms.
Frames 24 setting
To display the Audio Delay and Max Look-ahead
parameters in frames based on 24 frames per
second, set the Delay Unit parameter to Frames
24.
Frames 25 setting
To display the Audio Delay and Max Look-ahead
parameters in frames based on 25 frames per
second, set the Delay Unit parameter to Frames
25.
Frames 30 setting
To display the Audio Delay and Max Look-ahead
parameters in frames based on 30 frames per
second, set the Delay Unit parameter to Frames
30.

Loudness Wizard – Format / Setup page
Use the Loudness Wizard’s Format / Setup page
to adapt Loudness Wizard’s format conversion
features to your station environment.
Setup section
Auto Detect parameter
Loudness Wizard’s automatic format detection
can be either time and level or dither-based.
To base format detection on input dither, set the
Detect parameter to a Bit-based setting. Avail-
able settings are 24, 20 and 16 Bit.
Dither settings should be preferred when dither
is managed actively by an upstream device, such
as the server or switcher.
To base format detection on audio, set the De-
tect parameter to a dB-based setting. Available
settings are -60 and -50 dB.
Auto Dissolve parameter
The UpCon algorithm crossfades in and out of
up-conversion in a power-compensated fashion.
Use the Dissolve parameter to set the cross-fade
engage and disengage time. Parameter range is
from 25 ms to 3 seconds.
Loudness Unit parameter
Use the Loudness Unit parameter to set the unit
in which loudness values are being displayed.
LKFS setting
To display loudness as LKFS, set the Loudness
Unit parameter to LKFS.
LUFS setting
To display loudness as LUFS, set the Loudness
Unit parameter to LUFS.
Mixdown section
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.
