Open or create a multitrack session containing the audio clip.
Auto Ducking allows for automatic computation of keyframes that lower the volume of a background sound against a foreground sound.

Open or create a multitrack session containing the audio clip.
Use the Essential Sound panel to tag the content to its specific type. You can duck clips tagged as music and ambience.
Select the background (for example, music) clip in the timeline, then assign it the Music audio type in the Essential Sound panel.
Click the checkbox next to Ducking to enable auto-ducking.
When you enable ducking, Premiere Pro adds an Amplify Effect to the clip. Keyframes that are computed by the Auto Ducking algorithm are added to this effect's gain parameter so that they can easily be changed or removed without interfering with your other sound design.
Make sure that you assign audio types to the other audio tracks so that Premiere Pro knows what track to use to drive the ducking.
Set the following auto-ducking options:
Click Generate Keyframes to compute and set keyframes for the Amplify effect that has been added to the clip.
You can manually change the keyframes after generation - however, clicking the Generate Keyframes button again overwrites all manual changes to the keyframes.
Premiere Pro automatically adds keyframes and ducking adjustments to the effect's rubberband. The Timeline clip's audio keyframe display also automatically switches to display the keyframes on the Amplify effect.
