In the top of the GUI you can read these metering data of a preselected source:
When you click on the little triangle
over here you will get a selection
of the measurement formats available:
This display also shows the duration
of the measurement. If the
Speech Gate
is active for the
Dialogue Intelligence™
algorithm, the numbers become yellowish
when the measurement has paused
because there is no speech detected for
the moment.
The other two buttons will control the measurement:

<start>

<continue>

Dialog Level (Dialnorm) Measurement:
Beside the ability to measure loudness by above standards, the
D*AP8
offers the feature to measure
the long-term A-weighted average level of dialogue within a presentation. A Dolby Digital / Digital plus
consumer decoder (e.g. a Set Top Box) will normalize the output level to -31dBFS by applying a shift
based on the Dialog Level parameter setting. The rule is: -31 - (dialog level value) = shift applied.
Example (dialog level measured = -23dB): -31 - (-23) = -8dB shift applied.

Speech Gate
The
Dialog Intelligence™
algorithm developed by
Dolby® Inc.
searches for portions of the audio content where
speech is present. Such portions may trigger the loudness
measurement. If it is activated and no speech is detected, the
number display becomes yellowish.
