Loudness Setup
The Loudness Setup folder allows you to customize the loudness settings of your meter.
You may use one of the Loudness presets as a starting point.
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 automatically be saved to the current preset.
Filter
Range: LEQM, K-Filter, Off
Sets weighting filter applied to the Loudness measurement.
ITU BS1770 loudness recommendation (R128, A/85) specifies K-filter weighting.
Scale Mode
Range: LU, LUFS, LKFS
The LU scale allows for a relative reference point in the loudness e.g. EBU R128 will mean 0LU=-
23LUFS, while SMPTE A/85 would mean 0LU = -24LKFS. The specific reference point may be
chosen via the 'Reference' parameter explained below.
LUFS and LKFS scales are identical scales, LUFS being used by EBU, while LKFS is used by
SMPTE.
Short-term Window
Range: Momentary, 3, 10 or 30 seconds.
The currently displayed loudness value is based on the averaged loudness values over the
defined time window. Setting the window to 'Momentary' essentially turns the Short-term
loudness reading into 'Momentary' loudness based on a sliding 300ms window. Please note that
the DK T7 already offers the Momentary reading alongside the Short-term loudness.
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.
EBU R128 specifies -23LUFS as the reference point.
SMPTE A/85 specifies -24LKFS as the reference point.
Peak Level
Range: -1 to -10 dBFS (1 dB steps).
The Peak level is a user defined reference point.
The peak level is dependent on the setting of 'Peak Mode'; True Peak or Digital (Sample Peak).
When the signal passes above the peak level, the Peak level readout will turn Red.
