Expand Audio object with empty space to create loop.

Hi Folks, How do you take a small segment of audio and add empty space to either side to say create a 4 bar loop? The audio segment I am working with has to be precisely placed and it is very difficult to work with. It would be easier embedded within a multi measure object. Thanks in advance for any advice you may have.
Best Wishes,
Dave

Okay, I figured it out. Simply select the region around the audio event and then select Audio > Bounce Selection. Works great!

Another alternative would be to take the Audio Event and put it into an Audio Part that is the size of the loop you want.
