-<h3>Normalize</h3>
+<h2>Label</h2>
<p>
-If enabled, peak levels of exported files will be normalized to the level chosen here.
+ The <kbd class="menu">Label</kbd> field allows to choose the name which will be
+ shown for this format in the drop-down list of export formats in the
+ 'File Formats' tab of the <a href="@@export-dialog">Export dialog</a>.
</p>
-<h3>Trim/Add silence at start/end</h3>
+<h2>Pre Process</h2>
<p>
-
+ If enabled, levels of exported files will be normalized to the level chosen here.
+ The normalization can be either:
</p>
-<h3>Compatibility/Quality/File format/Sample rate</h3>
-<h4>Compatibility</h4>
+<ul>
+ <li>Peak, which adjusts the gain to bring the highest signal peak to the
+ chosen level (in <acronym title="decibels relative to full scale">dBFS</acronym>),
+ </li>
+ <li>Loudness, which adjusts the gain to bring the average amplitude to the
+ chosen level (in <acronym title="loudness units relative to full scale">LUFS</acronym>),
+ without exceeding the chosen true-peak value (in
+ <acronym title="decibels true peak">dBTP</acronym>).
+ EBU R128 is only available for mono or stereo sounds while true-peak works
+ for any channel layout.
+ </li>
+</ul>
+
+<h3>Trim silence at start/end</h3>
<p>
-Selecting an item in the 'Compatibility' column will display options in the
-other columns that are incompatible with that item in red.
+ These checkboxes allow to remove any part Ardour considers silent (< −90dB),
+ at the beginning or/and end of each exported track.
</p>
-<h4>Quality</h4>
+<h3>Add silence at start/end</h3>
<p>
-The appropriate item in the 'Quality' column will be highlighted when you
-choose a file format. Clicking on items in the 'Quality' column currently
-doesn't seem to do anything useful.
+ These checkboxes allow to add silence at the beginning or/and end of each
+ exported track. The duration of the added silence can be manually fixed in the
+ adjacent 'timer' input fields.
</p>
-<h4>File format</h4>
+<h2>Watermark</h2>
<p>
-This column contains a list of Ardour's supported export file types. Click on
-the format you want to use.
+ This section adds watermarks to the exported audio (e.g. for limited/demo
+ distribution), by overwriting part of the audio with white noise in the
+ exported file.
</p>
-
-<h4>Sample rate</h4>
<p>
-You can explicitly choose the sample rate of your exported files here, or
-choose 'Session rate' to export in the current session's sample rate, without
-sample rate conversion.
+ Both the <dfn>Mode</dfn> (how often and how long) and <dfn>Noise Level</dfn>
+ (how loud) can be set.
</p>
-<h4>Sample rate conversion quality</h4>
+<h2>Format</h2>
+
+<h3>Compatibility</h3>
<p>
-If your chosen sample rate does not match the current session's sample rate,
-choose the sample rate conversion quality here. Better quality options are
-slower.
+ Selecting an item in the 'Compatibility' emphasizes the settings in the other
+ columns that are compatible with the selected standard, by turning incompatible
+ options red. When an incompatible quality/format/sample rate is selected, the
+ compatibility column checkbox disappears.
</p>
-<h3>Options</h3>
+<h3>Quality</h3>
<p>
-Options relevant to the chosen file format will appear here.
-Categories of audio file format are:
-<ul>
-<li>Linear encoding</li>
-<li>Broadcast Wave</li>
-<li>Ogg Vorbis</li>
-<li>FLAC</li>
-</ul>
+ The appropriate item in the 'Quality' column will be highlighted when a file format
+ is chosen. At the moment, selecting a Quality setting does not show the
+ compatible File formats.
+</p>
+<h3>File format</h3>
<p>
-Available options include a selection of the following:</p>
-
-<h4>Sample Format</h4>
+ This column contains a list of Ardour's supported export file types. Selecting
+ one updates the options underneath it.
+</p>
<p>
-Choose the bit depth of exported files.
+ Note: For mp3 export ardour relies on ffmpeg to encode the file. This comes bundled
+ with the video-tools (and is always available when you install the official Ardour
+ binary.
</p>
-<h4>Dithering</h4>
+<h3>Sample rate</h3>
<p>
-If the exported files bit depth is less than Ardour's native bit depth,
-choose the dithering algorithm to use.
+ A specific sample rate can be chosen for the exported files, or the current session's
+ sample rate (by choosing 'Session rate'), without sample rate conversion.
</p>
-<h4>Create CUE file/Create TOC file</h4>
+<h2>Encoding</h2>
<p>
-As well as exporting an audio file, create a file (in CUE or TOC format
-respectively) containg CD track information, as defined in the
-<a href="/ardours-interface/editor-lists/ranges-and-marks-list/">Ranges & Marks List</a>.
+ Options relevant to the chosen file format will appear just to the right of the
+ Compatibility/Quality/File format/Sample rate table.
+</p>
+<h3>Sample rate conversion quality</h3>
+<p>
+ In case the chosen sample rate does not match the current session's sample rate,
+ the sample rate conversion quality can be chosen here. Better quality options are
+ slower.
+</p>
-<h4>Tag with session's metadata</h4>
+<h2>Metadata</h2>
<p>
-If the exported file format supports metadata, use data entered in the
-<a href="/working-with-sessions/metadata/">Session Metadata</a>
-window to tag the exported files.
+ These options are presented whatever the chosen format is:
</p>
+<h3>Tag file with session's metadata</h3>
+<p>
+ If the exported file format supports metadata (e.g. FLAC, Ogg Vorbis), use data
+ entered in the <a href="@@metadata">Session Metadata</a> window to tag the
+ exported files.
+</p>
-<h3>Label</h3>
+<h3>Create CUE/TOC/chapter mark file</h3>
<p>
-The 'Label' field lets you choose the name which will be shown for this format
-in the drop-down list of export formats in the 'File Formats' tab of the
-<a href="/exporting/export-dialog/">Export dialog</a>.
+ As well as exporting an audio file, Ardour can create a file (in CUE, TOC or MP4ch format
+ respectively) containing CD track information, as defined in the
+ <a href="@@the-ranges-and-marks-lists">Ranges & Marks List</a>.
+ Those files can then be used to either burn a CD or DVD, or to create "chapters"
+ inside a compatible mp4 video container.
-<h3>Command to run post-export</h3>
+<h2>Post Export</h2>
<p>
-If this is not blank, it is considered as a command to be run after the export
-of each file. Either the command must exist in $PATH, or you can specify an
-absolute path to an executable file here.

-like. Currently these are:
-<dl>
-<dt><code>%f</code></dt>
-<dd>Full path & filename of the exported audio file</dd>
-<dt><code>%d</code></dt>
-<dd>Directory containing the exported audio file (including trailing directory separator)</dd>

+ For example, exporting an mp3 file can be done by inserting <code>lame -b320 %f</code>
+ which will convert the exported audio file ('%f') to a 320 kbs mp3 using the lame encoder
+ (provided lame is installed first on the system).
