+ The Loudness Analyzer and Normalizer is a tool that is useful at the
end of the mixing process to make the final audio file comply with
different specs regarding loudness.
</p>
+<p class="note">
+ This is a rather advanced mode. When using the Loudness Analyzer &
+ Normalizer (or <dfn>LAN</dfn>), one has to make sure than normalization
+ is disabled when exporting.
+ <br>
+ In general, it is recommended to just use <a href="@@export-format-profiles">
+ automatic export normalization</a>, in the <a href="@@export-dialog">Export
+ dialog</a>. This can also produce results for multiple targets at the
+ same time.
+</p>

<p>
It is enabled by checking
<kbd class="option">Enable master-bus output gain control</kbd> in the
- <a href="@@preferences#preferences-mixer">Preferences</a>.
+ <a href="@@preferences#preferences-signal_flow">Preferences</a>.
The <a href="@@master-bus-strip">Master Bus strip</a> then shows a <kbd class="menu">LAN</kbd>
button to start the analysis, and a volume slider that is the global gain
that can be set either manually or by the loudness normalizer.

+<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>:
+</p>
+
+<ul>
+ <li><span style="color:green;">Integrated loudness</span> averaging the loudness on the whole session</li>
+ <li><span style="color:red;">Short loudness</span> using a sliding time window of 3 seconds</li>
+ <li><span style="color:blue;">Momentary loudness</span> using a sliding time window of 400 ms.</li>
+</ul>
+
+<h2>Normalization Parameters</h2>
+
<p>
As loudness is a perceived sonic energy, and depends on the level, frequency,
duration and nature of the sound, this window allows to base the calculation
hence the correction to apply</li>
</ul>
-<p>
- At the top of the window, a <kbd>Show Graphical Analysis</kbd> button
- allows to visually represent the analysis with a graph in a very similar
- window to the one in the Post-<a href="@@export-dialog">Export</a> analysis.

+<h2>Presets</h2>

A selection of presets is offered to simplify the normalization. These
