Seems this had been broken for some time now, but nobody noticed it. :-/ Thanks to Len Ovens for pointing this one out. :-)

Recording and editing any serious session might leave the session with some
|
|
unused or misplaced files here and there. Ardour can help deal with this clutter
|
|
thanks to the tools located in the <kbd class="menu">Session > Clean-up</kbd>
|
|
menu.

<h2 id="bring_all_media_into_session_folder">Bring all media into session folder</h2>
|
|
|
|
<p>
|
|
When <a href="@@adding-pre-existing-material">importing media files</a>, if
|
|
the <kbd class="option">Copy files to session</kbd> has not been checked, Ardour
|
|
uses the source file from its original destination, which can help avoiding file
|
|
duplication. Nevertheless, when the session needs to be archived or transfered
|
|
to another computer, moving the session folder will not move those
|
|
<em>external</em> files as they are not in the folder, as seen in <a
|
|
href="@@backup-and-sharing-of-sessions">Backup and sharing of sessions</a>.
|
|
</p>
|
|
|
|
<p>
|
|
Using the <kbd class="menu">Bring all media into session folder</kbd> menu
|
|
ensures that all media files used in the session are located inside the
|
|
session's folder, hence avoiding any missing files when copied.

<h2 id="reset_peak_files">Reset Peak Files</h2>
|
|
|
|
<p>
|
|
Ardour represents audio waveforms with peak files, that are graphical images
|
|
generated from the sound files. This generation can be time and CPU consuming,
|
|
so it uses a cache of the generated images to speed up the display process. To
|
|
watch for files modification, Ardour relies on the file-modification time. If an
|
|
external file is embedded in the session and that file changes, but the
|
|
system-clock is skewed or it is stored on an external USB disk (VFAT), Ardour
|
|
can't know the change happend, and will still use its deprecated peak files.
|
|
</p>
|
|
|
|
<p>
|
|
Using the <kbd class="menu">Reset Peak Files</kbd> menu allows to reset this
|
|
cache, which frees up disk space, and forces the re-creation of the peak files
|
|
used in the session. It can prove useful if some waveforms are not used anymore,
|
|
or if a graphical or time glitch happens.

<h2 id="clean_up_unused_sources">Clean-up Unused Sources…</h2>
|
|
|
|
<p>
|
|
Recording usually leaves a lot of unused takes behind, be it in midi or audio
|
|
form, that can clutter the Region List, and eat up a lot of hard drive space.
|
|
While its generally a good practice to keep as many things as possible while
|
|
recording, when transferring or archiving the session, some clean up can help a
|
|
lot in reducing the sessions clutter and size.
|
|
</p>
|
|
|
|
<p>
|
|
Selecting <kbd class="menu">Clean-up Unused Sources…</kbd> will force
|
|
Ardour to detect those unused waveforms by looking for unused regions, and
|
|
(through a prompt) for unused playlists. The media files will not be destroyed,
|
|
though. At this stage, they are just copied in a particular place of the session
|
|
path (namely, in the <code>dead sounds/</code> sub-folder).
|
|

<h2 id="flush_wastebasket">Flush Wastebasket</h2>
|
|
|
|
<p>
|
|
Although Ardour is a <em>non-destructive</em> audio-editor, it allows for a
|
|
very careful destruction of unused media materials. This function is closely
|
|
linked to the previous one. When the unused sources have been cleaned up and
|
|
quarantined, the <kbd class="menu">Flush Wastebasket</kbd> menu will allow for
|
|
their physical destruction.
|
|
</p>
|
|
|
|
<p>
|
|
As a safeguarding mechanism though, Flushing the wastebasket in impossible
|
|
in the same working session as the Cleaning up of unused sources: the user needs
|
|
to close the session and reload it before flushing. It allows to test the
|
|
playback of the session and ensure both that Ardour did not commit any mistake
|
|
(unlikely, but better safe than sorry), and that the user is absolutely sure of
|
|
what he does.
|
|
</p>
|
|
|
|
<p class="warning">
|
|
All media destroyed this way is not sent to the system's <em>trash can</em> but
|
|
permanently deleted. If a file is mistakenly destroyed this way, the user will
|
|
have to rely on data recovery techniques to try getting it back.
