Measurements
The Measurements area displays results from the loudness measurements performed on the selected program
according to the settings made in the Loudness | Config tab and the Audio Programs panel. The three data boxes
show these values:
•
True peak MAX
Maximum true peak level found in all selected input channels
•
Momentary MAX
Loudness averaged over a 400 ms sliding rectangular time window
•
Short term (S)
Loudness averaged over the short-term time window
The chart shows a running plot of the last 15 seconds of the value of the Short Term (yellow trace) and Momentary
(green trace) loudness values. The bar graph at the right indicates the current Momentary value.
A reset, initiated by a user via the Reset button on the Loudness | Config tab, will reset all of these measurements.

•

every 24 hours after logging was enabled, until logging is disabled
•
when the reference changes
