defined above. Figure 2-9 shows an example of Integrated Level Gated loudness.
Examples of other loudness measurements are shown in Figures 2-10, 2-11, and 2-
12. The loudness measurements that may be shown are:
1.
Integ. Level Gated Loudness
: Loudness measurement is integrated over a
period, but gated by speech levels exceeding a certain level.
2.
S.T. 10s Ungated Loudness
: Short Term Loudness is measured over a
sliding 10 second interval.
3.
S.T. (3s)
: Short Term Loudness is measured over a sliding 3 second
interval.
4.
True Peak
: The True Peak Loudness is the loudest peak waveform over the
program period.
5.
Loudness Range
: The Loudness Range (LRA) is the measure of variation
between the calculated loudest and softest passage over the program period.
6.
Momentary
: Loudness is measured over a quick momentary interval.
7.
Dialnorm
: Loudness is measured according to the Dolby dialog
