3.2.2. Monitoring the Gain Applied
Program 1
The
Gain Applied
control will provide a real time value indicating the
amount of gain being applied by the IntelliGain
system. Values can
be either negative, indicating a gain reduction, or positive, indicating
gain is being applied.

3.2.3. Monitoring the Output Loudness
Program 1
The
Output Loudness
control will provide a real time value of the
calculated output loudness value. This control is used for monitoring
purposes only. It is used to provide confidence monitoring.

3.2.4. Monitoring the Integrated Loudness
Program 1
The
Integrated Loudness
control will provide a real time value of the
calculated integrated loudness value. This control is used for
monitoring purposes only.
The period of the integrated loudness measurement is defined by the
Start/Continue
and
Stop/Pause
buttons defined in sections 3.2.10 and
3.2.11. Once the
Stop/Pause
button is activated, the loudness of the
segment(s) defined by all active periods is calculated.
The integrated loudness measurement is performed using the gating
function specified in ITU-R BS.1770-2 summarized as follows:
-
an absolute gating threshold at -70 LKFS is used to compute
the absolute-gated loudness level
-
a relative gating threshold that is 10 LU below the absolute-
gated loudness level is applied
-
the measurement input to which the gating threshold is applied
is the loudness of 400 ms blocks with a constant overlap
between consecutive gating blocks of 75%

3.2.5. Monitoring the Maximum Loudness
Program 1
The
Maximum Loudness
control will provide a real time value of the
calculated maximum loudness value within the duration of the
Integrated Loudness
calculation. This control is used for monitoring
purposes only.
