Set the targeted loudness range target. Range is from '1.0' to '20.0'. Default value is '7.0'. Loudness range measures the variation of loudness on a macroscopic time-scale in units of LU (Loudness Units). For programmes shorter than 1 minute, the use of the measure Loudness Range is not recommended due to too few data points (Loudness Range is based on the Short-term-Loudness values (3-seconds-window)).
