Recording Audio Filter Automation
As long as the Record Audio Keyframes button at the top of the Audio Mixer is selected,
keyframes are recorded whenever an audio filter is adjusted during playback. Automation
recording begins when you position the pointer on an audio filter control and press the
mouse button, and recording continues until you release the mouse button. The number
of recorded keyframes depends on which option you choose from the Record Audio
Keyframes pop-up menu in the Editing tab of the User Preferences window.

3 through 7.
When you’ve finished making adjustments, stop playback.
After you’ve finished adjusting one audio filter control, you can move the playhead
back to the beginning to record automation for other controls. The changes you’ve
already made play back, so that you can make further adjustments in relation to those
you’ve already set. In this way, you can continue layering automation using different
audio filter controls until you’ve adjusted the filter to your satisfaction.
Note: You can also make changes to clips with filter parameters for which you’ve
already recorded keyframes. New changes made to audio filter controls overwrite
previously recorded keyframes.
