Chapter 6 Audio Regions 61
The E to the right of the other two markers represents the end of the Audio Region. If
moved, you will also alter the Region’s length in the Arrange window.
The Audio Window
Put simply, the Audio window allows to you to manage all audio files used in the open
song. Press Command-9 to open this window, or browse to it via the Audio > Audio
Window menu option. Alternately, you can switch to Screenset 7 in the default song
created by the Logic Setup Assistant.
Quickly Resizing Audio Regions
You can define Audio Region start and end points in either the Audio window, or
directly in the Arrange window. Either method is useful for roughly defining an Audio
Region’s size. If you need precise control over the Audio Region or file start and end
points (for loops and so on), please make use of the Sample Editor.
