Automatically duck audio
上次更新時間
2026年11月9日
Learn how to automatically duck audio and keep your audio mix balanced in Adobe Premiere.
Automatically lower background music when dialogue or voiceover is detected using the Essential Sound panel in Adobe Premiere. With Auto-update keyframes, ducking adjustments stay in sync as you edit your timeline, reducing the need to regenerate keyframes manually.
In the Essential Sound panel, assign an audio type to each clip. You can duck clips tagged as Music or Ambience.
Enable Ducking in the Essential Sound panel.
Keep Auto-update keyframes enabled to update ducking keyframes as you edit your timeline.
秘訣
You can manually adjust the generated keyframes. If Auto-update keyframes is enabled, making a manual edit automatically turns it off. When you enable Auto-update keyframes again, Premiere prompts you to keep or overwrite your existing keyframes. Selecting Generate Keyframes again overwrites any manual changes made to the generated keyframes.
Set the following auto-ducking options:
- Duck Against: Allows selection of icons for the audio content types you want to duck against—Dialogue, Music, Sound Effects, Ambience, or Un-tagged clips.
- Sensitivity: Adjusts the threshold at which the ducking triggers. Higher or lower sensitivity settings result in fewer adjustments, but focus on maintaining a lower or louder music track, respectively. Middle-range sensitivity values trigger more adjustments where the music comes in and out quickly between pauses in speech.
- Duck Amount: Controls how much the volume decreases during ducking. Adjusting this setting to the right reduces the volume more dramatically, and to the left for more subtle volume adjustments.
- Fade Duration: Controls how quickly the volume adjustment occurs when triggered. Faster fades are ideal when mixing fast music with fast speech, while slower fades are more appropriate when ducking background music behind voiceover tracks.
- Fade Position: Controls where the background audio fade occurs relative to the dialogue: outside, inside, or centered.
To manage ducking keyframes manually, turn off Auto-update keyframes, and then select Generate Keyframes.
