Audio ducking is an important audio editing technique used to automatically reduce background music or sound effects when dialogue or voice is present. It helps maintain clear speech and balanced audio in videos.
What is Audio Ducking
Audio ducking is the process of lowering the volume of one audio track (usually music) when another audio track (usually voice) becomes active.
Importance of Audio Ducking
Audio ducking improves speech clarity, enhances viewer experience, and ensures background music does not overpower dialogue.
How Audio Ducking Works
When a voice is detected, the editing software automatically reduces the volume of background music and restores it when the voice stops.

Audio ducking is commonly used in:
- YouTube videos
- Podcasts
- Interviews

Manual Audio Ducking
Editors can manually keyframe volume levels to reduce and increase music at the right moments.
