Loudness Setup

Filter
Range: K-FILTER or LEQM.
Two different scales have been adopted for displaying the loudness value. One of these is defined by the ITU in
their document ITU BS1771 and that uses “Loudness Units” - LU. These have values ranging from -18 to +9 with
the typical aiming point for signals being a specification close to the 0 point. The other commonly used scale has
only negative values going down from a 0 LUFS mark at the very top of the scale.
Short-term Window
Range: 0, 3, 10 or 30 seconds.
The currently displayed loudness value is based on the averaged loudness values over a defined time window.
Setting the window to 0 provides a display of values that are as instantaneous as the system permits. The
window can be adjusted to be 0, 3, 10 or 30 seconds.
Reference
Range: -9 and -24 dBFS (1 dB steps).
A range of Reference levels can be chosen for the purpose of loudness measurement as part of the loudness
measurement standard which your organization (or client) has adopted.
Tip: Select the Loudness Preset that comes closest to your desired loudness setting, then select the ‘User’
Loudness Preset in order to customize the details.
Your changes will now automatically be saved to the current preset.
