Audio Editor Keyframe Graph
The remainder of the window contains the keyframe graph. This area contains the curves
and keyframes for the level and pan of the selected track. Keyframes appear as diamonds,
and curves appear as solid lines. Areas before the first keyframe and after the last keyframe
are represented with dotted lines. The waveform of the selected track is displayed behind
the curves.
Audio track bar
At the top of the graph a green bar shows the duration of the audio file. As you change
the file’s In and Out points, the bar shrinks or expands to show the new duration.
As in the Keyframe Editor, you can manipulate keyframes here also by dragging them in
the graph. Moving a keyframe left or right changes its position in time, while dragging
it up or down changes its value. Because audio keyframes work exactly the same as
keyframes for other parameters, you can learn more about working with audio keyframes
in
Modifying Keyframes and Modifying Curves .
Ruler
At the top of the Audio Editor Keyframe graph is a ruler that provides a visual gauge for
the positions and durations of the level and pan keyframes and curves. The ruler in the
Audio Editor shows different time than the rulers in the Timeline and Keyframe Editor.
This ruler shows the time for the selected audio file rather than for the whole project.
The ruler can contain indicators to help mark important frames or sections of the project
such as the playhead, play range indicators (also called In and Out points), and markers.
The ruler can be viewed in either frames or timecode.
To change the ruler view format
µ
Control-click the ruler, then choose Display Frames or Display Timecode from the shortcut
menu.
Markers can be added to your project to identify an important frame or range of frames.
For more information on creating and using markers, see
Adding Markers .
