Audio ducking (similar concept to side-chaining) is used to automatically lower the volume of one track so that you can hear another track better. For example, if you have a video project that includes music and voiceover, you can use audio ducking to automatically decrease the music volume when the narrator is speaking. You can adjust the threshold that triggers "ducking" and you can adjust by how much the volume of the background track will drop.
|
• |
Ducking Level — determines the volume decrease. Higher numbers indicate lower volume. |
|
• |
Sensitivity — determines the volume threshold (read from the track above the selected track) required for ducking to occur. You will likely need to readjust the Sensitivity slider to achieve the results you want. |
In these examples, the voiceover is the purple track and the music is the blue track. The yellow line in each example indicates when and by how much the volume of the music track is lowered by applying different Sensitivity settings for Audio Ducking: Top = 0, Middle = 2, and Bottom = 30. In this example, a setting of 2 worked best.
You can use Audio Ducking with video clips that include audio (such a gameplay videos). How? Add your video clip to the Timeline, right-click the clip and choose Split Audio. Drag the resulting audio track to a music track. You can then record your narration to the voice track and apply Audio Ducking to the music track.
You can tweak Audio Ducking results manually by dragging, adding, or removing keyframe nodes on the yellow volume line.
