Processing section
Loudness Correct parameter
Use the Loudness Correct parameter to specify
if Loudness adjustment should be applied.
On
To switch on Loudness adjustment of the input
signal, set the Loudness Correct parameter to
On.
Off
To switch off Loudness adjustment of the input
signal, set the Loudness Correct parameter to
Off.
Look-ahead and Lip-
sync Delay section
Audio Delay parameter
Use the Audio Delay parameter to adjust AV
sync. You can change this parameter in real-time
without introducing clicks or pitch changes.
Setting the Audio Delay parameter to “0” results
in minimum latency (around 1 ms). The maxi-
mum value for the Audio Delay parameter is 10
seconds delay for each channel in a stereo stem.
If Audio Delay is enabled, some or all of it may
also serve as loudness control look-ahead.
Max Look-ahead parameter
The loudness correction module of the Loudness
Wizard algorithm may “look ahead” to evaluate
the input signal – thereby allowing adjustment to
start e.g. before a loud commercial.
The actual “look-ahead” section can never be
longer than the setting of the Audio Delay pa-
rameter. However, you can use the Max Look-
ahead parameter to use an even shorter section.
This is useful if you don’t want loudness adjust-
ment to set in too early, even with a high Audio
Delay setting (e.g. for Lip-Sync or for Profanity
prevention).
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.
