The LRA instrument provides a graphical representation of the Loudness
Range (LRA) descriptor. LRA is a statistical method used to measure the
variation of loudness across an entire program, where lower LRA values
represent lower program dynamics. In this way, the LRA measurement
can show whether a program has a continuously constant loudness (low
LRA values) or a high variation between low and high level components
(high LRA values).
