The Loudness Num instrument provides numerical readouts of the fol-
lowing loudness measurements:
•
M (Momentary): Summed momentary loudness measurements of the
individual channels using an integration time of 400
ms.
• S (Short Term): 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 buttons to execute this measurement.
• LRA : Loudness Range
• TPmax : The highest measured True Peak value in dBFS
• Mmax: The highest measured Momentary value
• Smax: The highest measured Shortterm value
• Itime : Duration of the current Loudness measurement
If needed, the numerical readouts of these individual loudness measu-
rements can be activated or disabled individually. The values of current
running measurements for I, LRA, TPmax Mmax, and Smax values will
be colored green, those of stopped measurements yellow. If values are
exceeding the upper limits, they will be colored red.
