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
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
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 the start of selected region(s) to the end of the previous region. If the region is too short, it is extended to its maximum to the left.|
|Trim to Next (k)||Trim the end of selected region(s) to the start of the following region. If the region is too short, it is extended to its maximum to the right.|
