Adjust volume in Effect Controls

Select an audio clip in a sequence.
In the Effect Controls panel, click the triangle next to Volume to expand the effect.
Do any of the following:
- Enter a value for the level. A negative value decreases the volume level and a positive value increases the volume level. A value of 0.0 represents the original clip’s volume level without adjustment.
- Click the triangle next to Level to expand the effect options, and then use the slider to adjust the volume level.
  
  A keyframe is automatically created at the beginning of the clip’s timeline in the Effect Controls panel.
(Optional) To change the Volume effect over time, move the current‑time indicator and adjust the volume level graph in the Effect Controls panel.
Each time you move the current‑time indicator and make an adjustment, a new keyframe is created. You can also adjust the interpolation between keyframes by editing the keyframe graph. Repeat as needed.
