Dialog normalization: Here you can set the level of spoken dialogs in dB. This value
will be used to adjust the total volume of DVD movies and different programs that
can be received by the DVB. To do this, you must first measure the volume of spoken
dialogs in your movies. The values 1 to 31 correspond to volume levels of -1 to -31 dB.
Note: Use the mixer's peakmeter to set the volume level. This process produces only
approximate results because the exact measurement requires a mean value, which
cannot be easily measured with MAGIX Video Pro X6.
The displayed value serves also as a reference value for "Dynamic Range Control".
Areas that are softer than speech will be made louder, and louder areas will be made
softer to avoid overmodulations.
Calculation example for "Normalization dialog"
Let's assume you have created a movie in MAGIX Video Pro X6 and dubbed it in
Samplitude/Sequoia. After the transfer of the surround tracks from
Samplitude/Sequoia (view page 205) you measure the volume of the spoken dialog.
The maximum
modulation level for Dolby
®
Digital audio is 31 dB over the set
reference value for surround stereo systems. For this reason the normalization dialog
has a value range of 1-31, describing the volume of the spoken dialog in dB.
If you have spoken dialogs with a volume level of, for example, -21 dB, you should
enter value "21" into the normalization dialog, so that the total volume can be lowered
to the reference level set in the surround decoder or amplifier. This is usually -31 dB
below the digital uppermost level.

Damping in Dolby

stream
-25 dB 25 -6 dB
-30 dB 30 -1 dB
-31 dB 31 0 dB
-5 dB 5 -26 dB
Note: The set value does not directly alter the created audio material, but simply
delivers information about the ideal damping to the surround decoder, making sure
that the dynamic range is not restricted.
