Pool
Every time that you record on an audio track, a file is created on your hard disk. A reference to this file, a clip, is added to the Pool.
The following rules apply to the Pool:
All audio and video clips that belong to a project are listed in the Pool.
Every project has a separate Pool.
The way the Pool displays folders and their contents is similar to the way the File Explorer/macOS Finder displays folders and file lists. In the Pool, you can perform operations that affect files on disk and operations that only affect clips.
Operations That Affect Files
Importing clips (audio files can automatically be copied and/or converted)
Converting file formats
Renaming clips (this also renames the referenced files on disk) and regions
Deleting clips
Preparing file archives for backup
Minimizing files
Operations That Affect Clips
Copying clips
Auditioning clips
Organizing clips
Applying audio processing to clips
