Instrument
The Loudness Numeric instrument provides numerical readouts of the
following loudness measurements:
• M (Momentary): Summed momentary loudness measurements of the
individual channels using an integration time of 400
ms.
• S (Shortterm): Summed loudness measurement using an integration
time of 3 s and a sliding window.
• I (Integrated): Overall program loudness between start and end
points that are entered manually. Use the Start, Stop
and Reset Loudness buttons to execute this measu-
rement.
• LRA: Loudness Range
• TPmax: The highest measured True Peak value in dBTP
If needed, the numerical readouts of these individual loudness measure-
ments can be activated or disabled individually. The values of current run-
ning measurements for I, LRA, and TPmax values will be colored green,
those of stopped measurements yellow. If values are exceeding the upper
limits, they will be colored red.

ments:
