Looping and Stretching Clips¶
You can change the duration of clips either by looping or stretching the content.
Looping a clip¶
To loop or set the duration shorter than the content of the clip, move the mouse cursor to the upper part of the right clip border so that the normally arrow shaped mouse cursor turns into a loop cursor.

Now hold the mouse button down while you move the cursor to the left or to the right to extend or shorten the clip. When you release the mouse button, the clip length is fixed. If you extend the clip you can see that the repeating sequences are always colored alternately light and dark.
Stretching a clip¶
As mentioned, you can also stretch the clip to match the tempo of the project. This involves processing the clip content with the time stretching algorithm in Acoustica.
To stretch a clip, move the mouse cursor to the button part of the right clip border so that the mouse cursor turns into a double sided arrow pointing left and right before holding down the mouse button.

Now hold the mouse button down while you move the cursor to the left or to the right to stretch the clip. When you release the mouse button, the time stretch will be applied to the clip.
