Auto Audio Ducking

Audio ducking means lowering the volume of things like background music in order for your dialogue to be heard more clearly. Here are the steps about how to apply it.

1 Select the clip or clips you want to apply audio ducking to (select the clips you want to hear more clearly, not the ones you want to lower the volume on). 

2 Right-click and choose Edit Properties or double-click it.

3 Find the Ducking option and select the lower volume of other clips. A slider will appear, which you can use to adjust the volume.
