<p>
<dfn>Session properties</dfn> control aspects of the workflow or
configuration that pertain to the current session only; these settings are
initially set from the template used to create the session. They can be found
in <kbd class="menu">Session &gt; Properties</kbd>, and are stored in the
session file.
</p>
<p>
Preferences are grouped by category:

<ul>
<li>
<dfn>Timecode Settings</dfn>
<ul>
<li>
2022-06-19 09:34:31 -04:00
<dfn>Timecode frames-per-second</dfn>: defines how many frames of
timecode are in one second. This can differ from the actual frame rate
depending on the standard used.
</li>
<li>
2022-06-19 09:34:31 -04:00
<dfn>Pull-up / pull-down</dfn>: sets the speed correction to match one
actual second, e.g. a 4.1667 pull-up matches a 24fps cinema movie to a
25 fps PAL TV broadcast format.
</li>
</ul>
</li>
<li>
<dfn>Ext Timecode Offsets</dfn>
<ul>
<li>
2022-06-19 09:34:31 -04:00
<dfn>Slave Timecode offset</dfn>: when an external timecode source is used,
adds or substracts the specified offset to the received timecode (MTC or LTC).
</li>
<li>
2022-06-19 09:34:31 -04:00
<dfn>Timecode Generator offset</dfn>: adds the specified offset to
the timecode generated by Ardour (so far only LTC) before sending it to
the external synchronized system.
</li>
</ul>
</li>
<li>
<dfn>JACK Transport/Time Settings</dfn>
<ul>
<li>
<dfn>Ardour is JACK Time Master (provides Bar|Beat|Tick and other information
2022-06-19 09:34:31 -04:00
to JACK)</dfn>: aside from synchronizing any JACK slave, Ardour can also
provide musical time information (Bar/Beat/Tick) for the current absolute
position for all the JACK-aware clients (N.B. the first jack client that
asks for this wins).
</li>
</ul>
</li>
</ul>
2019-07-30 10:14:34 -04:00
<h2 id="properties-sync">Sync</h2>
<ul>
<li>
<dfn>A/V Synchronization</dfn>
<ul>
<li>
<dfn>Use Video File's FPS Instead of Timecode Value for Timeline and Video
2022-06-19 09:34:31 -04:00
Monitor</dfn>: when checked, uses the timecode FPS value of the standard
2019-07-30 10:14:34 -04:00
used by the video file instead of forcing the FPS set in the <a href="#properties-timecode">
Timecode tab</a>.
</li>
<li>
<dfn>Apply Pull-Up/Down to Video Timeline and Video Monitor (Unless using
2022-06-19 09:34:31 -04:00
JACK-sync)</dfn>: allows to apply the pull-up/down as set in the <a href="#properties-timecode">
Timecode tab</a> to the <a href="@@video-timeline-and-monitoring">video
timeline</a> as displayed in the editor and to the Video Monitor, resulting
in a shorter/longer video in the editor and a speed-up/down in the Video
Monitor.
</li>
</ul>
</li>
</ul>
2019-07-30 10:14:34 -04:00
<h2 id="properties-fade">Fades</h2>
<ul>
<li>
<dfn>Audio Fades</dfn>
<ul>
<li>
2022-06-19 09:34:31 -04:00
<dfn>Declick when transport starts and stops</dfn>: creates an artificial
fade in/out when starting or stopping playback, to avoid the 'click' sound
resulting in starting it at a non zero value.
</li>
<li>
2022-06-19 09:34:31 -04:00
<dfn>Declick when monitor state changes</dfn>: also creates an artificial
fade in/out to avoid clicks when a parameter in the monitor changes.
</li>
<li>
2022-06-19 09:34:31 -04:00
<dfn>Region fades active</dfn>: when checked, Ardour applies the region
<a href="@@create-region-fades-and-crossfades">crossfades</a> to each
region's start and end. When unchecked, no fades are applied, and clicks
may be heard at regions boundaries.
</li>
<li>
2022-06-19 09:34:31 -04:00
<dfn>Region fades visible</dfn>: when checked, the region fades are visible
in the the Editor. Unchecking may increase readability for sessions made
of a lot of tiny regions.
</li>
</ul>
</li>
</ul>
2019-07-30 10:14:34 -04:00
<h2 id="properties-media">Media</h2>
<p>
Change how sound is stored on disk. These options do not change how sound is handled
internally.
</p>
<ul>
<li>
<dfn>Audio File Format</dfn>
<ul>
<li>
2022-06-19 09:34:31 -04:00
<dfn>Sample format</dfn>: defaults to 32-bit floating point, the same as
the internal representation. 24 and 16-bit integer representation are
also available, for more lightweight sessions at the cost of a reduced
audio definition.
</li>
<li>
2022-06-19 09:34:31 -04:00
<dfn>File type</dfn>: defines what format is used to store the audio
files. The default is WAVE, and can be changed to Broadcast Wave to
store metadata and timecodes, <abbr title="Core Audio
Format">CAF</abbr> to overcome WAVE's limitation to 4Gb in size, RF64
to add more channels, etc. The chosen format is usually very
workflow-specific.
</li>
</ul>
</li>
</ul>
2019-07-30 10:14:34 -04:00
<h2 id="properties-locations">Locations</h2>
<p>
These options add file locations that will be searched to find the audio and
midi files used by the session. This is useful when the files have been
imported into the session but not copied into the session.
</p>
<ul>
<li>
<dfn>File Locations</dfn>
<ul>
<li>
2022-06-19 09:34:31 -04:00
<dfn>Search for audio files in</dfn>: allows to add a location to look
for audio files. Adding a location is done by navigating to the
directory where the files are stored, selecting it and clicking <kbd
class="menu">Open</kbd>. The directory will show up in the dialog. The
<kbd class="menu">Remove</kbd> button next to the added directory can
be used to remove it from the search path. Multiple paths can be added
this way.
</li>
<li>
2022-06-19 09:34:31 -04:00
<dfn>Search for MIDI files in</dfn>: is exactly the same, but for MIDI files.
</li>
</ul>
</li>
</ul>
2019-07-30 10:14:34 -04:00
<h2 id="properties-filenames">Filenames</h2>
<p>
This tab is used to change how Ardour names recorded regions.
</p>
<ul>
<li>
<dfn>File Naming</dfn>
<ul>
<li>
2022-06-19 09:34:31 -04:00
<dfn>Prefix Track number</dfn>: when checked, a unique number will
appear on each track in the Editor window and will prefix the region
name. If the track number is <samp>2</samp> and the region would have
been named <samp>Gtr-1.1</samp>, with track number prefix turned on the
region will be named <samp>2_Gtr-1.1</samp> instead. See <a
href="@@region-naming">Region Naming</a>.
</li>
<li>
2022-06-19 09:34:31 -04:00
<dfn>Prefix Take Name</dfn>: when enabled, the first time a track is
recorded it will have the specified take name. When recording is
stopped, any trailing number on the end of the take name will be
incremented by 1. If the specified track name doesn't have a number on
the end, the number <samp>1</samp> will be suffixed.
</li>
<li>
<dfn>Take name</dfn> specifies what name is prefixed if <kbd
class="option">Prefix Take Name</kbd> is checked.
</li>
</ul>
</li>
</ul>

<h2 id="properties-misc">Misc</h2>
<p>
This tab has several things that don't fit on the other tabs.
</p>
<ul>
<li>
<dfn>MIDI Options</dfn>
<ul>
2022-09-20 12:02:03 -04:00
<li>
<dfn>Draw tool creates opaque MIDI regions</dfn>: if selected, creates
MIDI regions that, when placed on top of other regions, don't mix with
content below during playback.
</li>
<li>
2022-06-19 09:34:31 -04:00
<dfn>MIDI region copies are independent</dfn>: if selected, when a MIDI
region is copied or duplicated, the new region is not linked to the
region it was copied from. If it is not selected, the copied regions
are linked and any editing done on one of the linked regions changes
all of the linked regions.
</li>
<li>
<dfn>Policy for handling overlapping notes on the same MIDI channel:</dfn>
2022-09-20 12:02:03 -04:00
selects how Ardour reacts to possibly conflicting MIDI notes:
<ul>
<li>never allow them</li>
<li>don't do anything in particular</li>
<li>replace any overlapped existing notes</li>
<li>shorten the overlapped existing note</li>
<li>shorten the overlapping new note</li>
<li>replace both overlapping notes with a single note</li>
</ul>
</li>
</ul>
</li>
<li>
<dfn>Glue to Bars and Beats</dfn>
<ul>
<li>
2022-06-19 09:34:31 -04:00
<dfn>Glue new markers to bars and beats</dfn>: if checked, a newly
created marker will always be placed at the nearest musical time
instead of right where the mouse pointer is.
</li>
<li>
2022-06-19 09:34:31 -04:00
<dfn>Glue new regions to bars and beats</dfn>: same as above, for regions.
</li>
</ul>
</li>
<li>
<dfn>Metronome</dfn>
<ul>
<li>
2022-06-19 09:34:31 -04:00
<dfn>Always count-in when recording</dfn>: when checked, waits for two
bars before the actual recording begins. The Metronome will tick (even if
disabled) during the count-in. Same as recording with <kbd
class="menu">Transport &gt; Record w/Count-In</kbd>.
</li>
</ul>
</li>
<li>
<dfn>Defaults</dfn>
<ul>
<li>
2022-06-19 09:41:17 -04:00
