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 audio level and pan keyframes applied. How these changes are made
depends on whether or not keyframe recording is turned on.
• 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 changed 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 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” and “Panning Audio in the Timeline.”
To modify pan keyframes you’ve added using the panning sliders in the Audio Mixer
Do one of the following:
µ
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.”
µ
In the Timeline, click 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.
Deleting Audio Level and Pan Keyframes
You can easily remove level and pan automation from clips in a sequence using the
Remove Attributes command. Audio level and pan keyframes can be removed separately
or together.
