Editing Files That Are Associated with a Multitrack Project in the File Editor Tab
You can nondestructively edit and apply effects to audio files used in a multitrack project in the File Editor tab. It is easy to open a single file from the Timeline of a multitrack

When you work on individual files in the File Editor tab, you don’t need to save or update individual audio files. Saving the multitrack project automatically saves all the individual audio files associated with the multitrack project.
Tracking File and Clip Relationships
One thing you do need to keep track of is the relationships between multiple clips that refer to the same audio file.
If you apply an effect to an .aiff file in a multitrack project, Soundtrack Pro creates an audio file project (.stap) from the original file to allow you to edit the file nondestructively, and the effect is applied as an action to the new .stap file.
The situation is complicated when multiple clips refer to the same audio file.
For example, if you drag three copies of a .wav file into the Timeline of a multitrack project, you create three new clips, each pointing to the original .wav file. When you select one of the new clips to begin editing it, a new audio file project is created from the .wav file that the clip refers to. Any edits you make are applied to the new audio file project, and then all three clips are updated to point to the new audio file project that was created.
The example above is useful when you want to do file cleanup operations such as noise reduction across multiple clips that share the same file. Applying an effect to any one of the clips will edit all the clips that point to that file. However, what if you want to edit the audio in a single clip?
To edit a single clip (and not the rest of the clips associated with the source file), you create an independent audio file project. This makes a new audio file for each selected clip. Creating an independent audio file also conveniently trims the file to match the original clip’s length.
