Regions can be stretched or shrunk in length without changing their
|
||
Pitch by using the **Stretch/Shrink Regions** tool (shortcut "*T*", for
|
||
"Time stretch").
|
||
|
||
A small adjustment to the length of a Region may not
|
||
cause noticeable sound **Artifacts**. However, the more extreme the
|
||
change in length, the more obvious the effect of processing on the
|
||
sound.
|
||
|
||
|
||
|
||
To use **Stretch/Shrink Regions**, place your cursor on top of the
|
||
region, and then Click-drag left or right. While dragging, you will see
|
||
a highlighted area, which represents the new duration to which the
|
||
Region will be shrunk or stretched when you release the mouse at the
|
||
current position.

## Time-Stretching a Region to Fit the Loop
|
||
|
||
In the image below, we've added another sound sample—this time, a
|
||
synthesizer line—from [freesound.org](http://www.freesound.org) to the
|
||
rhythmic passage we composed in the **Creating Looped Sections** chapter
|
||
(search for "1168 so synth" in the **Search Freesound** tab of Ardour if
|
||
you'd like to get the same sample. Import it as a new track).
|
||
|
||
After importing this synth line, we see that the length of our new
|
||
Region doesn't match the existing rhythm we've already created. It's too
|
||
long to be one bar and too short to be two bars.
|
||
|
||
|
||
|
||
We can correct this by using the Stretch/Shrink tool. Select the Region
|
||
you wish to stretch, and drag the new length to the end of the second
|
||
Bar, again assisted by the Grid settings.
|
||
|
||
When you release the mouse button, the **Time Stretch Audio** dialog will
|
||
appear. You can experiment with different settings for the Time Stretch
|
||
operation. Each will affect the sound in different ways. It's a good
|
||
idea to experiment with a few different stretch settings to find out
|
||
which gives the result you're most happy with.
|
||
|
||
|
||
|
||
Click **Stretch/Shrink** in the Time Stretch dialog to start the
|
||
operation.
|
||
|
||
When the Time Stretch operation is complete, the region of the
|
||
synthesizer line will now be exactly two Bars long, and should fit in
|
||
with the rhythm we already created with the drum samples.
|
||
|
||
|
||
|
||
## Continuing

This was the last chapter of the **Editing Regions** section. Next we go into Mixing.
