Adjusting the output volume of a project

You can adjust the output volume of a project using the master volume slider, located below the lower-right corner of the timeline. Adjusting the master volume controls what the volume will be when the project is exported. You should adjust the output volume to a level high enough to eliminate background noise, but not high enough to cause clipping.

The master volume slider is intended to control the output, or export, volume of the project. Use your computer’s volume control to adjust the volume at which you listen to the project play.

To adjust the output (master) volume:

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).

As the project plays, watch the master level meters located above the master volume slider. Before you export a project, make sure the small red dots to the right of the level meters are not lit. These dots (called clipping indicators) light to show that the volume level of the project at some point is too high, which will cause distortion or “clipping” in the exported project.

For information about preventing and fixing clipping, see Related Topics below.
