Sections of audio are called _regions_ in Ardour. To compose the short rhythmic
|
||
passage we've been working on, we will need to know how to _select_, _move_,
|
||
_split_ and _trim_ these regions, as well as how to _fade in_ or _fade out_
|
||
their volume and create _crossfades_ between them. Some of these options may
|
||
need to happen at specific _edit points_ in the composition, or according to the
|
||
musical _meter_ we can define with the _timeline_ and the _grid_ as well.
|
||
|
||
## Selecting Regions
|
||
|
||
The _Grab_ mode (**G** shortcut) is the tool to select and move objects. It is
|
||
located just below the transport menu in the _Editor_ window (the little "hand"
|
||
icon). You will use this tool a lot in your Ardour work.
|
||
|
||
|
||
|
||
When it is active, your mouse pointer will look like a little hand icon.
|
||
|
||
Try all of the operations below, for practice:
|
||
|
||
- Click on the waveform of the region to select it. Click and drag on a region
|
||
to move it around (left and right within the same track, but also up and down
|
||
onto other tracks).
|
||
|
||
- Use **Ctrl+Click** to create and drag around a _copy_ of the region.
|
||
|
||
- You can select multiple regions by holding the **Shift** key while clicking
|
||
on each region you want to select.
|
||
|
||
- You can also drag a selection box over multiple regions to select them all.
|
||
|
||
|
||
|
||
- Move multiple regions at the same time after selecting them.
|
||
|
||
- You can select several sequential regions on one track all at once by holding
|
||
down the **Shift** key while selecting the first and the last regions of the
|
||
sequence (copy a few regions on the same track to try this out).
|
||
|
||
- When you select a single region, make sure to click on the waveform section of
|
||
its rectangle. The lower stripe with the region name is used for a different
|
||
action (see the _Trimming Regions_ section below).
|
||
|
||
- Use the **Del** key to delete selected regions.
|
||
|
||
- Standard copy (**Ctrl+C**), cut (**Ctrl+X**), and paste (**Ctrl+V**)
|
||
operations also work with regions.
|
||
|
||
## Moving Regions
|
||
|
||
While moving a region, a _timecode_ will appear on the screen in yellow numbers.
|
||
This timecode is the region's starting point on the timeline. The unit of this
|
||
timecode is the same as the unit of the primary clock, which you can change by
|
||
right-clicking on the clock and choosing a new unit (_Minutes:Seconds_,
|
||
_Bar:Beats_, etc).
|
||
|
||
You can move regions horizontally (sideways) to a different point in time on the
|
||
same track, or you can move the selected region vertically (up or down) to a
|
||
different track.
|
||
|
||
When a set of one or more regions is selected, you can move the whole set by
|
||
dragging with the mouse.
|
||
|
||

|
||
Make sure to select the region in its waveform section, because selecting the
|
||
bottom title bar area is used for a different action (see _Trimming Regions_
|
||
below).

## Duplicating Regions
|
||
|
||
In addition to **Ctrl+Click+Drag** and standard copy/paste, Ardour offers
|
||
other handy ways to duplicate regions. Use the _Grab_ mode (select/move
|
||
objects) to select one or more regions, then use the _Duplicate_ function to
|
||
make one or more copies (menu `Regions > Duplicate`). Three options are
|
||
available:
|
||
|
||
- _Duplicate_ (shortcut **Alt+D**): make a copy of the selected region on
|
||
the same track, immediately after the original.
|
||
|
||
- _Multi-Duplicate_ (shortcut **Shift+D**): make multiple copies of the
|
||
selected region at once (same track, in sequence). You can specify the number
|
||
of duplications.
|
||
|
||
- _Fill Track_: make as many copies of the selected region as needed to fill
|
||
the entire track, all the way up to the _End_ marker on the timeline.
|
||
|
||
In the following screenshot, regions have been duplicated using the methods
|
||
above.
|
||
|
||
{{< figure alt="Duplicate" src="en/Ardour4_Region_Duplicate.png" >}}
|
||
|
||
## Using Edit Points
|
||
|
||
When you use the standard copy/cut/paste commands, where exactly will the
|
||
regions be pasted? The exact location is determined by the edit point
|
||
drop-down menu.
|
||
|
||
|
||
|
||
If _Mouse_ is selected as the edit point, the copied region will be pasted at
|
||
the current position of the mouse.
|
||
|
||
If _Playhead_ is selected as the edit point, the copied region will be pasted
|
||
at the red playhead line on the same track where the original region is.
|
||
|
||
Finally, if _Marker_ is selected as the edit point, then the copied region
|
||
will be pasted immediately after the currently selected _location marker_.
|
||
|
||
## Markers
|
||
|
||
It is very useful to be able to tag different locations in a session for later
|
||
use when editing and mixing. Ardour supports several ways for doing this. The
|
||
most common method is using _location markers_, which define specific positions
|
||
in time.
|
||
|
||
Location markers can be added to the timeline by right-clicking on the
|
||
_Location Markers_ strip and selecting _Add New Location Marker_. If you don't
|
||
see the _Location Markers_ strip, right-click on the timeline and select it to
|
||
make it visible. Location markers can also be selected with the mouse and
|
||
moved to new positions. Right-clicking on a location marker lets you rename
|
||
the marker, among other options.
|
||
|
||
{{< figure alt="Location Marker" src="en/Ardour4_Location_Marker.png" >}}
|
||
|
||
{{% notice tip %}}
|
||
When you first create a new session, two location markers are automatically
|
||
added by default. These are the _start_ and _end_ markers that you see in
|
||
the screenshot above. If you don't see the _end_ marker, zoom out enough and
|
||
you will find it.

||
|
||
## Splitting Regions
|
||
|
||
To _split_ a region simply means to divide a single region into two independent
|
||
regions. There are two ways of accomplishing this:
|
||
|
||
* You can use the _Cut_ mode (**C** shortcut) to point and click anywhere you
|
||
want to split; or
|
||
|
||
* You can stay in the _Grab_ mode and use the **S** shortcut (for "Split").
|
||
In this last case, the point at which a region will be split depends on the
|
||
currently selected edit point. If _Mouse_ is selected as your current edit
|
||
point, select a region and place the cursor at the point you would like to
|
||
_Split_, then type **S**" (same as going to menu `Edit > Split Region`).
|
||
|
||
{{< figure alt="Split" src="en/Ardour4_Split_Region.png" >}}
|
||
|
||
After being split, the original single region becomes two independent regions,
|
||
with a new name for each, as in the image above. The two new regions are now
|
||
entirely independent. You can move and edit them separately.
|
||
|
||
{{< figure alt="Split" src="en/Ardour4_Split_Region_Moved.png" >}}
|
||
|
||
Regions can also be split by using the playhead or a marker as the edit point.
|
||
|
||
The split regions will receive a name derived from the original name of its
|
||
parent region, and you will see this reflected in your regions list. For
|
||
example, in the image above, you see two regions called _pink.15_ and _pink.16_,
|
||
which means there were split from a parent region called "pink" (not shown in
|
||
image).
|
||
|
||
{{% notice tip %}}
|
||
Splitting ranges will follow your grid settings. For example, if you have an
|
||
active grid set for bars, splits will happen at the bar boundaries. If you
|
||
choose _No Grid_, splits will happen wherever the edit point is, regardless of
|
||
any grid.
|
||

|
||
|
||
## Trimming Regions
|
||
|
||
If you move the cursor near the left or right side edge of a region, you will
|
||
see that the pointer becomes an arrow. Click and drag inwards from either end
|
||
of the region, and the region will be shortened accordingly. This is called
|
||
_trimming_ the region. Regions can be trimmed from the start of the region
|
||
(drag from left to right at the edge) or from the end (drag from right to
|
||
left).
|
||
|
||
This action is non-destructive: no audio is actually being deleted. It is as
|
||
if you were just "hiding" those portions of the region that you don't want or
|
||
don't need anymore. Later on, you can "un-trim" the region (i.e., extend it
|
||
back to its original full size), even if it has been moved or copied to a new
|
||
track.
|
||
|
||
{{< figure alt="Trim" src="en/Ardour4_Trimming_Regions.gif" >}}
|
||
|
||
{{% notice tip %}}
|
||
Like splitting, trimming will obey grid settings. If you don't want your
|
||
trimming to be constrained to any grid, simply turn the grid off (_No Grid_).
|
||
{{% /notice %}}
|
||
|
||
## Deleted Regions
|
||
|
||
Because Ardour is non-destructive, the regions you have deleted from tracks
|
||
are not completely removed from the session. They can always be accessed again
|
||
from the region list on the far right side of the _Editor_ window (Regions can
|
||
be dragged from the list onto any tracks).
|
||
|
||
## Creating Fades in Regions
|
||
|
||
A _fade_ is a change in the volume of a region, either as the region starts or
|
||
as it ends. A fade at the start of the region is a _fade in_, and at the end
|
||
of a region it is a _fade out_. Each region has two small handles along the
|
||
top corners, which can be dragged inwards from either edge to create a fade in
|
||
or fade out. The screenshot below shows a fade in (indicated by the shaded
|
||
area).
|
||
|
||
{{< figure alt="Fades1" src="en/Ardour4_Fades_1.png" >}}
|
||
|
||
In fact, every region has a fade in and fade out built-in. By default, the
|
||
region fade is very short and serves to avoid clicks in the transitions at
|
||
the start and end of the region. By adjusting the regions fade length as shown
|
||
above, a more gradual transition can be accomplished.
|
||
|
||
By right-clicking on one of the fades (the shaded area), the speed of the fade
|
||
can also be adjusted.
|
||
|
||
{{< figure alt="Fade Options" src="en/Ardour4_Fade_Options.png" >}}
|
||
|
||
## Crossfading Between Two Regions
|
||
|
||
When one region fades out while another fades in, this is called a
|
||
_crossfade_. If the two regions are in different tracks, you can use the
|
||
method described above with the fade in and fade out handles. The following
|
||
screenshot shows an example.
|
||
|
||
{{< figure alt="Crossfade" src="en/Ardour4_Crossfade_1.png" >}}
|
||
|
||
However, if both regions are in the same track, you need to overlap them in
|
||
order to create a crossfade. When regions overlap on the same track, Ardour
|
||
treats them as *layers*, that is, one of the regions is considered to be on
|
||
top of the other. The important rule to understand is:
|
||
|
||
*The fade in (or fade out) of the topmost region represents the crossfade
|
||
between the two regions.*
|
||
|
||
Once you understand this principle, it's easy to create and control crossfades
|
||
between regions. Here's an example. The two separate regions seen below will
|
||
be made to overlap in order to create a crossfade.
|
||
|
||
{{< figure alt="Crossfade2" src="en/Ardour4_Crossfade_2.png" >}}
|
||
|
||
Note that we did not add any extra fade out to the first region, but we did
|
||
add a longer fade in to the second region. Then we drag the second region
|
||
partly on top of the first:
|
||
|
||
{{< figure alt="Crossfade3" src="en/Ardour4_Crossfade_3.png" >}}
|
||
|
||
The fade in of the second region works now as the crossfade between the two
|
||
regions. In other words, the first region will fade out in a mirror image way
|
||
as the second region fades in.
|
||
|
||
In order for this to work, though, we need to make sure that the region that
|
||
has the desired fade is *on top* in Ardour's layering system. In order to
|
||
change layering of regions, select a region and go to the menu `Region >
|
||
Layering`.
|
||
|
||
|
||
|
||
The difference may be hard to hear if you are doing this with the very short
|
||
percussive sounds we imported earlier. To really hear the effect, import a
|
||
couple of longer samples to try it out (for example, a sample of rain sounds,
|
||
and another of a human voice). Overlap several seconds of your long samples on
|
||
the same track. You will hear the difference as you move the second region to
|
||
the bottom (_Lower to Bottom_), and then back to top (_Raise to Top_). When
|
||
it's on top, we will hear the desired crossfade. When it's at the bottom, we
|
||
will hear no crossfade, just an abrupt change from first to second region
|
||
(assuming your first region has no fade out specified, as in the screenshots
|
||
above).
|
||
|
||
## Using Grid Settings
|
||
|
||
Experiment with the _Grid Mode_ setting, as discussed in the _Setting Up the
|
||
Timeline_ chapter, to give different kinds of quantization — in other
|
||
words, to constrain the boundaries of each region to certain grid points.
|
||
Here, the grid has been activated and set to _Beats/16_, to quantize the
|
||
regions to sixteenth notes within each bar. You may wish to trim the endpoints
|
||
of some of the samples, as discussed above, to fit within the metric structure
|
||
you have set up.
