Audio Basics
An audio file usually remains unchanged on the hard disk, even
if you choose to edit small excerpts from the file for playback in
Logic fun. This is non destructive, "region based" editing.
As a recording medium the hard disk has an advantage over
magnetic tape, because you never have to rewind or fast-
forward it. As a result, you are able to move from one area of
work on the hard disk to another, almost instantly. You can
simultaneously use audio files which are located at different
places on the recording medium. Most edits of audio recordings
only affect the way in which Logic fun plays back the files,
without actually affecting the stored data on the disk(s)—an
actual cut or deletion does not take place. Thus, every edit of
any audio recording performed in the Arrange window can be
undone at anytime later. This is what is known as non-destruc-
tive editing. Programmable CD players operate on a similar
principle. If you want to listen to the songs on your CD in the
reverse order from the way they appear on the CD, your CD
player does not actually change the data on the CD. That
would be destructive. The program only plays the songs in the
reverse order—non-destructively.

Regions

With non-destructive editing you do not change the audio file
itself, but rather the so-called "regions". By regions, we mean
excerpts of the audio file. The audio file itself is unaffected
when the regions are defined.
When you record an audio file with Logic fun, a region is auto-
matically created which encompasses the entire length of the
audio file.
Regions can be defined in the Sample editor. They are also
created, when you edit recordings in the Arrange window.
As many regions as you like can be defined from each audio file.
