Making an Independent Copy of a Clip
Any time you use multiple instances of the same clip in a multitrack project, the clip refers
to the same source media file. This means that any time you modify the media file, all of
the clips that refer to the media file are affected. How do you edit just one clip without
editing its source media? In cases where you only want to make changes to a single clip,
you can make a new copy of the clip’s media file in a new audio file project and link this
clip to the new audio file project.
To create a copy of a clip’s media file and link the clip to the new audio file project
1 Select the clip whose source media file you want to copy.
2 Control-click the clip in the Timeline, then choose Replace with Independent Audio File
Project from the shortcut menu.
A new Soundtrack Pro audio file project is created that includes a copy of the original
audio file. Only media between the clip’s In and Out points is copied, plus handles on
either side for later trimming, if necessary.
The new audio file project opens in the File Editor tab and the clip now links to the new
audio file project.
Note: The default handle duration is 5 seconds. To adjust the handle duration, go to
Soundtrack Pro > Preferences > General.
Using the Multitrack Timeline and the File Editor Together
One of the unique advantages of Soundtrack Pro is the combination of nondestructive
waveform editing in the context of a multitrack Timeline. This section focuses on how
you can exploit this powerful toolset in your sound editing project.
