Trimming Regions

Changing the length of a region is a very common editing operation, often known as trimming. There are several ways to accomplish this with Ardour, and some very useful specialized trimming operations.

Drag-Trimming With the Mouse

Trimming region - before Trimming region - after
Trimming region - before and after

In Grab mode, moving the pointer near the beginning or end of the region changes the cursor to indicate that trimming is possible, and the edge of the region can then be Left-dragged in both directions.

Trimming will obey Snap settings.

Other Trimming operations

There are several commands for region trimming. Some use the edit point to determine where to trim to. Some are not bound to any keys by default (but could be via the Keybindings Editor).

These command are both in the Region > Trim main menu (with a region selected) or in the contect menu of a region, right click on a region > Name_Of_The_Region > Trim

Trim Start at Edit Point (j)
Trim selected region(s) start to edit point.
Trim End at Edit Point (k)
Trim selected region(s) end to edit point.
Trim to Loop/Punch
Trim selected region(s) beginning and end to the loop/punch boundaries (if it exists).
Trim to Previous (j)

Trim to Next (k)
