Visualizing Loudness Monitoring
When you show the track of a Main bus in the Timeline, as long as the track is high enough
(ahem, tall enough), you can show or hide a series of “Loudness History” curves to visualize the
loudness analysis of the mix on that bus over the duration of the mix.
The available curves are:
Integrated: A thick curve shows the averaged “integrated” loudness analysis of the
current mix, which is a measurement that’s taken from the beginning to the end of
playback. This graph is the primary gauge of whether or not measured loudness is
acceptable. The color of each segment of this curve indicates whether that part of the
mix is “to spec.” Blue indicate loudness levels that are below tolerance, yellow indicates
loudness values that are within tolerance, and red indicates loudness values that are
above tolerance. By evaluating the colors of the curve, you can easily spot which parts
of your mix might need adjustment to meet the necessary specification.
Momentary: A measurement of the loudness measured in the past 400ms, shown by a
thin green-blue curve, which provides an analysis of transient level changes.
Shor t Term: A measurement of the loudness of the past 3 seconds, shown by a thin
blue line, which provides a more averaged analysis than the Momentary curve, yet still
indicates the dynamics of the mix.
To show the loudness history for Main 1:
1 Open the Automation controls by clicking the automation button on the Fairlight toolbar.
2 Open the Index, and click the eye button for the Main you want to see in the Timeline.
Loudness History appears as an option in the track header controls as long as the track
is tall enough to show the controls. These controls will be hidden on short tracks.
3 Turn on the Loudness History toggle, and check the curves you want to see. The
Integrated, Momentary, and Short Term loudness analyses can be individually
displayed or hidden, to expose overlapping graphs in that track in which you can see
your program’s loudness over time.
