Using the Audio Mixer to Record Over Previously
Existing Automation
You can use the Audio Mixer to make further changes to audio clips in your sequence
that already have level and pan keyframes applied. How these changes are made
depends on whether or not the Record Audio Keyframes button is selected.
 If the Record Audio Keyframes button is selected: Changes you make with the Audio
Mixer during playback create a new set of keyframes, completely overwriting any
previously existing keyframes. Changes you make while playback is paused insert
new keyframes at the position of the playhead.
 If the Record Audio Keyframes button is not selected: Changes you make with the
Audio Mixer during playback do not create new keyframes. Instead, existing
keyframes are modified to match the levels set when the playhead passes over them.
Individual keyframes can be adjusted if the playhead is directly over them. If the
playhead is between two keyframes, the level of both keyframes is raised to adjust
that entire section of the overlay.
During playback, every fader and panning slider in the Audio Mixer animates,
displaying the current levels in your sequence. At any time during playback, you can
adjust a fader or panning slider to begin recording new automation or modifying
existing automation. This helps you to maintain a smooth transition from any
previously recorded levels to the new levels you’re setting.
Modifying Keyframes in the Timeline and Viewer
You can also make changes directly to the audio level and pan keyframes in the
Timeline. By displaying level overlays in the Timeline (click the Clip Overlays control),
you can modify the keyframes you recorded, using the Selection and Pen tools to make
precise adjustments. For more information on adjusting audio level and pan keyframes
in the Timeline, see “
Adjusting Audio Levels in the Timeline
To modify pan keyframes you’ve added using the panning sliders in the Audio Mixer,
you can do one of the following:
 Open the clip in the Viewer. Stereo pan keyframes appear on their own overlay in the
clip’s Audio tab. For more information on adjusting stereo pan keyframes in the
Viewer, see “
Changing the Pan of Audio in the Viewer
 In the Timeline, enable the Clip Keyframes control, then control-click in the Keyframe
editor area of an audio track and choose Pan from the shortcut menu. Pan keyframes
are now displayed in the keyframe editor for the audio tracks in the Timeline, and
you can adjust them with the Pen tool.
