Editing a Sound Clip in the Waveform Editor
As a first step in audio editing in Soundtrack Pro, you should clean up your individual audio files using the Waveform Editor.
The Waveform Editor allows you to do very fine edits of a single audio file, such as cutting out small imperfections or other unwanted segments that you can see more clearly in a waveform view of the audio file.
After you're done cleaning up your individual audio files in the Waveform Editor, then you can place them in the multi-track area to the right and beginning editing your final audio sequence.
At the new screen give a name to your file (such as the name of the original file followed by edited) and save it in the same folder as all your other audio files.
The audio file then will appear in its own window, where you can edit the sound wave for the audio.

Play the audio file by pressing the space bar on your computer.
You can zoom in on the waveform by holding down the Apple key and then pressing the + key.
You can zoom out by holding down the Apple key and then pressing the - key.
Marking Clip Segments in the Waveform Editor
In the waveform editor, you also can add markers at precise locations in your audio clip. Then you can cut out any unwanted segments of your audio between the markers.
You add a marker to the waveform by moving the playhead to the place where you want the marker to appear and pressing M on your keyboard.
A green marker that looks like a tiny upside-down house will appear exactly where the playhead is located.

If you want to specify a more exact placement of your marker, you can click on the time code and type in a specific time. Your playhead will automatically move to that point and you can press M to set a marker. You can also grab and drag a marker to a new point in your timeline.
Next, add another marker using the same procedure.
To eliminate an audio segment between two markers, double click on the audio waveform anywhere between the two markers to highlight the segment.
Then click on the delete key on your keyboard to remove the segment.
