1130 Chapter 13 Working with Audio
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 select the Master track by clicking its area at the bottom of the Audio tab. When
selected, the Master track area appears highlighted.
Turning the Master Track On or Off
The Master track is turned on by default. When it is turned off, no sound is audible
when 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.
To turn the Master track on or off:
m Click the checkbox at the left side of the Master track. Click the checkbox again to
return the Master track to its previous state.
When the master track is selected, a master waveform appears in the Audio Editor.
Setting Master Level
You can use the Master Level slider to set the overall volume level for the audio in your
project.
To set the master level:
m Drag the Master Level slider to set the level you want.
The Master level works in conjunction with the level setting for each individual track.
For example, if you set a track’s level to 0.5 and you set the master level to 0.5, the
combined level is 0.25 (one-fourth) of the original.
Note: If you raise both an individual track’s level and the Master level so that the
combined increase is greater than 2, you may cause audio distortion or “clipping.” For
information about how to prevent clipping, see “Preventing Clipping” on page 1131.
