Using Add Edit When Trimming
When you are trimming with several audio tracks in sync, the Add Edit button allows you to create an edit in the silent or black areas of the synced tracks. They occur in line with the track you are trimming, and they trim all the tracks at once to maintain sync.
Add Edit button
To use the Add Edit button while trimming:
1.  Move the position indicator to the edit that you want to trim.
2.  Select only the additional tracks that are in sync, and click the Add Edit button in the Timeline top toolbar.
The system adds a transition at the location of your position indicator in the Timeline.
3.  Select the transition and trim (be sure to select all the synced tracks).
As you trim, frames are also added or removed from the additional tracks.
4.  When you have finished trimming, you can remove the add edits from the synced tracks by clicking each Add Edit transition and by pressing the Delete key.
