Increase or decrease the volume level based on which the clips should play.

Step 3: Adjust Volume and Add Keyframe

The easy option of modifying the audio keyframe is from the Audio panel that will navigate by double-clicking on the audio keyframe created on the timeline.

Yes, from the options provided, you can slide the parameters like pitch, equalizer, ducking, and denoise if required to modify the keyframe.

Yes, in the upcoming session, we can see how to fade audio with keyframes, but here let’s look at the other options.
