Setup GUI – MEASUREMENT

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> / <pause> / <continue>

x <reset>.

Dialog Level (Dialnorm) Measurement:

Beside the ability to measure loudness by above standards, the MAP 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.

Dialog Intelligence™ [OFF / Active]

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.
