|
|
using the <em>Stretch/Shrink Regions</em> tool (<strong>T</strong> shortcut, for “Time-stretch”).</p><figure><img src=en/ardour7-stretch-shrink-edit-mode.png alt="Stretch/Shrink Regions tool"></figure><p>A small adjustment to the length of a region may not cause noticeable sound
|
|
<em>artifacts</em>. However, the more extreme the change in length, the more obvious
|
|
the effect of processing on the sound.</p><p>To use <em>Stretch/Shrink Regions</em>, 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. Ardour will also
|
|
display the new duration of the region next to the highlighted area in units of
|
|
the primary clock.</p><figure><img src=en/ardour7-stretch-shrink-highlight.png alt="Stretching highlight"></figure><h2 id=time-stretching-a-region-to-fit-the-loop>Time-Stretching a Region to Fit the Loop</h2><p>In the image below, we’ve added another sound sample—this time, a <a href=https://freesound.org/people/walkerbelm/sounds/1168/>synthesizer
|
|
line from freesound.org</a>
|
|
to the rhythmic passage we composed in the <em>Creating Looped Sections</em> chapter.</p><p>After importing this synth line, you will see that the length of the 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. More importantly, while the first note matches
|
|
the beginning of the kick drum’s sound above, the second note is clearly
|
|
off-beat.</p><figure><img src=en/ardour7-stretch-shrink-1.png alt="Non-matching regions"></figure><p>We can correct this by using the <em>Stretch/Shrink</em> tool. Select the region you
|
|
wish to stretch, switch to the tool, click on the right side of the region, then
|
|
drag the cursor until the newly created highlight area matches the new length,
|
|
that is, all the way to the second bar (again assisted by the <em>Grid</em> settings).</p><figure><img src=en/ardour7-stretch-shrink-action.png alt=Stretching></figure><p>When you release the mouse button, the <em>Time Stretch Audio</em> dialog appears. You
|
|
can experiment with different settings for the <em>Time Stretch</em> operation. Each
|
|
will affect the sound in a different way. It’s a good idea to try different
|
|
stretch settings to find out which one gives you the result you’re most happy
|
|
with.</p><figure><img src=en/ardour7-stretch-shrink-2.png alt="Time Stretch Audio dialog"></figure><p>Click <strong>Stretch/Shrink</strong> in the <em>Time Stretch Audio</em> dialog to start the
|
|
operation.</p><p>When the 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.</p><figure><img src=en/ardour7-stretch-shrink-3.png alt="Stretched audio region"></figure><h2 id=continuing>Continuing</h2><p>This was the last chapter of the <em>Editing Regions</em> section. Next we go into
