<h2>The Loudness Graph</h2>
<p>
At the top of the window, a loudness graph visually represents the
analysis. The x-axis represents the time, and the y-axis represents
the perceived loudness in <abbr title="Loudness Units referenced to
Full Scale">LUFS</abbr>:

At the lower end of the window is a <em>Conformity Analysis</em> folding
info panel that is opened by clicking its title, and indicating, for each
of the presets above, if the corrected gain would fit the required values:
New presets can be created at will and saved/removed using the <kbd>Save</kbd>
