Analysis 25 – 641
Loudness distribution tool
This analysis tool measures the most frequent loudness found in an audio
file (this is different from average loudness). The graphic peaks found by
the analysis represent these values.
The following parameters can be set:
Parameter Description
Resolution Loudness is the average audio volume computed over a given period.
This parameter represents this period. Smaller time values are more
suited for sections with abrupt changes in level, like drum hits.
Left/Right Allows you to display the loudness in both channels or either the left
or right channel in a stereo file.
Mono/Mix For a stereo file, this option displays a single graph (average left/right).
Display range This adjusts the vertical ruler range, so you can zoom-in the graph
(Auto mode has to be off).
Auto When this is activated, the vertical ruler is automatically adjusted to
optimize the display.
Analysis 1-3 You can store 3 different graphs, which is useful for comparison pur-
poses. When comparing similar curves, you should switch off Auto
mode, to keep the same scale for each analysis.
