Working With Audio Files
Projects can potentially contain thousands of audio files that
you need to manage and edit.
Audio file management tasks, such as renaming, creating backups, or converting to
other formats are best handled in the Audio Bin.
Many audio file handling tasks, such as resizing, can be performed on regions—rather
than editing the underlying audio file. When you require extremely precise audio edits,
however, it’s best to use the Sample Editor.
Editing Audio Files
Even though the Arrange window allows you to edit regions with sample accuracy,
there are a number of jobs that you may need to perform directly on the underlying
audio files. As examples:
 Precisely setting the start and end points of an audio file when creating a loop.
 Changing the “downbeat” (known as the anchor in Logic) to ensure that your audio
file plays at exactly the right time.
 Reversing the audio file.
 Maximizing the gain, without clipping the audio file (a process known as
normalizing).
 Removing pops or clicks in your audio files.
All of these tasks, and many others, can be performed in the Sample Editor. Full details
on all Sample Editor commands and functions, along with usage examples, are found
in the “Editing Audio in the Sample Editor” chapter of the Logic user manual.
