The visualization component displays a continuously evolving real-time view of your source, target, and output loudness over time. There are currently two main types of visualizations: history and histogram. History displays a rolling window of the most recent history of loudness samples. Histogram divides this history up into buckets and displays the relative proportion of each bucket in real-time.
You can hover the mouse over a bucket to see the loudness range the bucket corresponds to.
The visualization component also displays the source range and target range, including knee width, allowing you to precisely target these ranges based on the dynamics of the audio. Detailed visualization settings can be adjusted from the visualization tab, with some features also available by right clicking on the visualization component.
You can double-click the visualization component to resize and hide everything else.
