Metadata Path program definition
If Metadata from the path is selected as the source, the Manual Coding Mode pulldown is disabled.
The Program Select switcher allows the user to select from among up to eight available programs (program 1 is the
default selection).
Once a program is selected, its Dialnorm and Coding Mode are extracted and displayed in the data boxes below the
switcher.
Note that:
• If the user selects Metadata path as the source, but no metadata is present, the selection defaults to Manual
mode.
• In Manual mode, there is no dialnorm to extract.
Measurements
The Measurements area displays results from the loudness measurements performed on the selected program
according to the settings made in the Config tab. The three data boxes show these values:
• Short term (S)
Loudness averaged over the short-term time window set in the Config tab.
• 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
