Overview
The History meter panel draws traces over time for the following loudness measurements: Integrated, Short-term, and Momentary. To learn more about the different loudness measurements, see the Loudness chapter.
Resizing
The History meter can be resized using the following methods:
- Clicking and dragging the bottom right corner of the main Insight plug-in window up or down.
- Clicking and dragging the dividers between meter panels.
- Clicking the maximize/minimize toggle button in the upper right hand corner of the History meter panel.
Displays and Rulers
Cursor Position Readout
When hovering the cursor over the history graph, a text readout will appear with information about the measurements at that point in time. Current time; M = Momentary; S = Short-term; I = Integrated.
Integrated Loudness Target Line
The Integrated loudness target set in the Loudness meter panel is indicated by the horizontal dotted red line displayed in the loudness history graph.
When the Integrated loudness trace has exceeded the Integrated target, the trace will be drawn in red.
Integrated Loudness Trace & Gate
The Gate selection in the Loudness meter panel influences the values used to draw the Integrated loudness trace.
See the Loudness chapter for more information about the Gate options.
Dialogue-Gated Loudness: Initial Drawing Delay
- The algorithm used to calculate dialogue-gated loudness requires at least two seconds of incoming audio in order to begin detecting dialogue content in the input signal.
- This two second delay can be observed in the initial drawing of the following measurements:
- Dialogue-gated Integrated measurements in the Loudness meter panel.
- The Short-term, Momentary, and Integrated loudness traces in the History meter panel.
- This delay does not affect the accuracy of the loudness measurements.
- For more information about dialogue-gated loudness measurements, see the Loudness meter chapter.
Zooming
- Zoom on the time scale or loudness scale by hovering the cursor over the axis and using the mousewheel or trackpad to zoom in or out.
- Click and drag on the time or loudness scales when zoomed in to modify the view range.
- Double-click on the time or loudness scales to reset the zoom level to default.
Options
The History meter options menu can be accessed by clicking the gear button in the upper left-hand corner of the History meter panel. The History options tab allows for individual loudness trace visibility to be toggled on or off.
Enable or disable the history trace displays using the following options:
- Display integrated loudness trace: Shows/hides the integrated loudness history trace.
- Display short-term loudness trace: Shows/hides the short-term loudness history trace.
- Display momentary loudness trace: Shows/hides the momentary loudness history trace.
Global Options: Loudness History CSV Export
- The Global Options window includes an option to export a .csv file of loudness history values.
- To access the Global Options window, click on the gear button in the upper right-hand corner of the Insight 2 plug-in window.
- Learn more about the Loudness options in the Global Options chapter.
