Working with Regions
Regions are the basic elements of editing and composing in Ardour. Each
region represents a single, contiguous section of one or more audio
files. Regions are defined by a fixed set of attributes:
the source audio file(s) they represent
a starting point in the audio file(s)
a length
When placed into a
playlist, they gain
additional attributes:
a position along the timeline
a layer
There are other attributes as well, but they do not
define the region. Things you should know about regions:
Regions are Cheap
By themselves, regions do not consume hardly any of your
computer's resources. Each region requires a small amount of
memory, and represents a rather small amount of CPU work if placed
into an active track. So, don't worry about creating regions
whenever you need to.
Regions are not audio files
Although a region can represent an entire audio file, they are
never equivalent to an audio file. Most regions represent just
parts of an audio file(s) on disk, and removing a region from a
track has nothing to do with removing the audio file(s) from the
disk ((the Destroy operation, one of Ardour's
few destructive operations, can affect this)). Changing the length
of a region has no effect on the audio file(s) on disk. Splitting
and copying regions does not alter the audio file in anyway, nor
does it create new audio files ((the Export ,
Bounce and Reverse
operations do create new audio files)).
Region Naming
Regions are initially named using either:
the name of the playlist for which they were recorded
the name of the embedded/imported audio file they represent
Whole File Region Names
These are not audio files, but regions that represent the full
extent of an audio file. Every time a new recording is done, or a
new file is embedded/imported, a new region is created that
represents the entire audio file(s) This region will have the name
of the playlist/original file, followed by a "-" and then a number.
For recorded regions, the number will increase each time a new
recording is made. So, for example, if there is a playlist called
"Didgeridoo", the first recorded whole file region for that playlist
will be called "Digderidoo-1". The next one will be "Digeridoo-2"
and so on.
For imported/embedded files, the region name will be based on the
file name, but with any final suffix (e.g. ".wav" or ".aiff")
removed.
Normally, whole file regions are not inserted into tracks/playlists,
but regions derived from them are. The whole-file versions live in
the editor region list where they act as an organizing mechanism for
regions that are derived from them.
Normal Region Names
When a region is inserted into a track/playlist, its initial name
will end in a version number, such as ".1" or ".103". For a recorded
region, if the whole file region was "Hang drum-1", then the region
in the track will appear with the name "Hang drum-1.1". For an
imported/embedded region, if the whole file region was
"Bach:Invention3", then the region in the track will appear with the
name "Bach:Invention3.1".
Copied Region Names
If the region is a copy of another region, it will begin life with
the same name as the original. When an operation is carried out that
modifies one of the copies, that particular copy will be renamed by
incrementing the version number.
Renaming Regions
You can rename a region at any time. Use the region
context menu to popup the rename dialog. The new name
does not need to have a version number in it (in fact, it probably
should not). The region will retain its name until it is modified
after being copied.
Selecting Regions
In general, operations on regions apply to whichever regions are
currently selected .
To select a single region, click on it using
Button1.
To add an unselected region to the currently selected regions, click
on it using
ShiftButton1.
To remove a selected region from the currently selected regions, click
on it using
ShiftButton1.
Removing Regions
Select the region(s) to be removed. Then press the "Delete" key or use
the standard key binding for "Cut" (
CtrlX by
default).
Note that "removing" a region is a non-destructive operation. It has
no effect on the audio file(s) stored on disk. If you really want to
destructively remove the region, use the context menu for the region
which has a "Destroy" item. This is not guaranteed to remove the audio
file from your disk storage, but it generally will.
Moving Regions
To move a region, make sure you are in object
mouse mode. Move the mouse pointer into the waveform display part of
the region, press Button1 and drag. The
region will follow the mouse pointer as you move it around. By
default, the region can move freely along the timeline - see
for information on how to force the
region to align to certain kinds of points along the timeline.
To move a region from one track to another, simply start a move as
described above, but move the mouse pointer into the desired track.
The region will follow the mouse pointer. Note that if you have other
kinds of "tracks" visible, the region will remain where it is as the
mouse pointer moves across them, and will then jump to the new track.
This serves as a visual reminder that you cannot drag an audio region
into an automation track or a bus, for example.
Moving more than one region
To move multiple regions, select them before moving. Then click+drag
on one of the selected regions. All the regions will move, keeping
their positions relative to each other.
Fixed-time motion
Sometimes, you want to move a region to another track, but keeping
its position along the timeline exactly the same. To do this, use
Button2 rather than
Button1.
Copying Regions
To copy a region, make sure you are in object
mouse mode. Move the mouse pointer into the waveform press the
Ctrl key, keep it down while pressing
Button1 and drag. A new region is created
and will follow the mouse pointer as it moves. See
for more details on moving the copied
region around.
Copying more than one region
To copy multiple regions, select them before copying. Then
click+drag on one of the selected regions. All the regions will be
copied and as they move, the will keep their positions relative to
each other.
Fixed-time copying
If you want to copy region(s) to other track(s) but keep the copies
at the exact position on the timeline as the originals, simply use
CtrlButton2
instead of
CtrlButton1.
