Audio Play Range Controls
The second row provides two controls to set the In and Out points for the audio file.
Changing a file’s In or Out point in the Audio Editor is reflected in the Timeline as well.
The area of the track between the In and Out points is the region used when “Use marked
region” is turned on in the playback controls.
Note: The In and Out points of the master track cannot be modified.
Level Controls
The third row contains controls to adjust and keyframe the level of the selected audio
track.
Activation checkbox:
This checkbox at the left of the row turns the display of the level
animation curve on and off. It does not disable existing level settings or prevent you from
making new settings.
Level:
A slider and value slider that control the level (volume) of the track. If the playhead
is currently positioned on a keyframe, the slider controls the level of that keyframe. If the
playhead is not on a keyframe, the slider adjusts the entire curve.
Pan Controls
The fourth row contains controls to adjust and keyframe the pan (left-right balance) of
the selected audio track.
Activation checkbox:
This checkbox at the left of the row turns the display of the pan
animation curve on and off. It does not disable existing pan settings or prevent you from
making new settings.
Pan:
A slider and value slider that control the left-right balance of the track. If the playhead
is currently positioned on a keyframe, the slider controls the pan setting of that keyframe.
If the playhead is not on a keyframe, the slider adjusts the entire pan curve. Negative
numbers move panning to the left, while positive numbers move panning to the right.
When the value is zero, the balance is split evenly between left and right. You can use
the value slider for more precise control.
Animation Menu
Appears to the right of the Level and Pan value sliders and is similar to the Animation
menu found in the Keyframe Editor. The menu is represented by different icons depending
on the current state of the parameter. For a table describing the different icons, see
Animation menu:
The commands within the Animation menu are listed below.
• Enable/Disable Animation: Turns keyframing on and off for this parameter. Once
keyframes are added, choosing Disable Animation does not delete the keyframes, but
just globally hides their effect.
• Reset Parameter: Removes any keyframes and restores the parameter to its default
value.
