You can adjust the overall volume of a project using the master volume slider. The master volume controls what the volume will be when you export the project. Use your computer’s volume control to adjust the volume at which you listen to the project play.
In general, you should adjust the output volume to a level high enough to eliminate background noise, but not high enough to cause clipping. You can check for clipping by watching the clipping indicators in the master level meter.
You can also make changes to the master volume level over time by editing the Master Volume automation curve. When the Master Volume automation curve is active, you can’t adjust the master volume slider.
To adjust the master volume slider:
In the control bar, drag the master volume slider left (to lower the output volume) or right (to raise the output volume).
Option-click the slider to return it to a neutral value (0 dB gain).
To check for clipping:
As the project plays, watch the master level meter located above the master volume slider. The small red dots at the right of the level meter (called clipping indicators) light whenever the volume level is too high, producing distortion or “clipping” in the exported project.
If the clipping indicators light, see “Prevent clipping” for information about how to eliminate clipping.
To edit the Master Volume automation curve:
- Choose Track > Show Master Track.
- Choose Master Volume from the menu in the master track header.
- Add control points to the master volume curve at the places where you want to change the overall volume of the project.
- Move the control points up or down to adjust the depth (intensity) of the volume changes.
