 Level slider: This slider adjusts the amplitude, or volume, of the currently selected
audio clip between +12 and –inf dB. As you drag the slider, the number in the dB
field and the level overlay line are both updated.
You can also adjust the volume by typing a number in the dB field to the right of the
Level slider. The number you enter can include a decimal value, such as 6.23.
If there are no level keyframes in the current clip, adjusting the Level slider affects the
level of the entire clip. If there are level keyframes, using this slider will either:
 Adjust the level of a keyframe at the current position of the playhead.
 Add a new keyframe to the level overlay and adjust it to the new level.
A change in level between any two keyframes appears as a slope on the level overlay
line in the Audio tab of the Viewer. Changes to the level overlay in the Viewer are
mirrored by the level overlay on that clip in the Timeline.

Tip: Hold down the Command key while dragging the Level slider to adjust the audio
level with more precision.
 Level Keyframe button: The keyframe button to the right of the Level slider places a
keyframe at the current playhead location on the level overlay. You can use
keyframes to adjust the audio level of your clip over time.
 Level keyframe navigation buttons: These buttons, to the left and right of the Level
Keyframe button, allow you to move the playhead forward or backward from one
keyframe on the level overlay to the next. You can also press Shift-K or Option-K,
respectively.
 Pan slider: This slider works in two ways, depending on what kind of audio you’ve
opened in the Viewer:
 If the clip items in the audio tab are a stereo pair, this slider simultaneously adjusts the
left and right stereo placement of both tracks. The default setting of –1 sends the left
track to the left channel output and the right track to the right channel output. A
setting of 0 outputs the left and right tracks equally to both speakers, essentially
creating a mono mix. A setting of +1 swaps the channels, outputting the left track to
the right output channel and the right track to the left output channel.
 If the clip items in an audio tab are single, mono tracks, this slider lets you pan the
audio track in the current audio tab between the left and right output channels.
As with the Level slider, if there are no pan keyframes in the current clip, adjusting
the Pan slider affects the pan of the entire clip. If there are pan keyframes, using this
slider will either:
 Adjust the pan of a keyframe at the current position of the playhead.
 Add a new keyframe to the pan overlay and adjust it between the left and right
output channels.
A change in pan settings between any two keyframes appears as a slope on the pan
overlay in the audio tab of the Viewer.
