Locking Tracks
Locking a track prevents it from being edited. When a track is locked, you cannot mute

play the track, and turn it on or off.

Working with the Master Track
Each project has a Master audio track. The controls for the Master track are located at the
bottom of the Audio tab, below the individual audio tracks. Using the Master track’s
controls, you can make changes that affect the final mixed output of all audio tracks. For
example, you can lower the volume of all tracks at once, or pan all tracks to the left or
right. In addition, you can turn the Master track on or off, or mute it.

you play the project, and no audio is included when you export your project. When it is
turned on, all audio tracks that are turned on are included in your export.
