Adjusting and Auditioning Track Boundaries
A track boundary must be selected before it can be adjusted or auditioned. To immediately select a track boundary belonging to the current track, use the 'Next Marker' or 'Previous Marker' command.
Once a track boundary is selected, you can easily re-position it by dragging it with the mouse while holding down the left mouse button.
At the top of the Track Boundary View window, a control bar enables you to set fade-in/out times and to insert pre- or post-track silence. See Adding Silence or Fade-In/Out to Boundaries for a description of this process.
You can audition your changes by using the 'Audition Track Boundary' toolbar button. See the Audition Track Boundary command for a description of this process.
