The Algorithm Settings menu contains all the values required to tailor the loudness measurement
functions for your specific purpose.
Frequency Weighting: ITU1770, Flat, Leq A, Leq B, Leq C, Leq D, ITU468, and Leq M measurements
are selectable to relate the ‘L’oudness of an ‘eq’uivalent amount of energy in a standard signal
Loudness Standard: Three different loudness standards are selectable when ITU1770 is selected for
Frequency Weighting: A/85 ATSC for USA; R128 EBU for Europe; and ARIB TR-B32 for Japan
Integration Time: Auto populates depending on which Loudness Standard is selected. A/85 ATSC =
10sec; R128 EBU = 3sec; ARIB TR-B32 = 3 sec. This can be set manually from 1 to 60 seconds.
Loudness Gating: is READ ONLY. For A/85 ATSC it is set to Disabled; R128 EBU and ARIB TR-B32
it is set to Relative
Absolute Level: is READ ONLY. For A/85 ATSC it is N/A; R128 EBU = -70 LUFS; ARIB TR-B32 = -70
LKFS
Relative Level: is READ ONLY. For A/85 ATSC it is N/A; R128 EBU = -10 LUFS; ARIB TR-B32 = -10
LKFS
Block Period: is READ ONLY. For A/85 ATSC it is N/A; R128 EBU and ARIB TR-B32 = 400ms
