How to Fade Audio in After Effects:

While After Effects is mostly known for its visual effects, it’s got some pretty solid audio editing features too. A key parameter you’ll work with is Audio Levels which is essential for adjusting volume.

Ready to learn how to fade audio? Here’s a step-by-step guide:

Step 1: Start by importing your audio file into After Effects. Simply drag and drop it into the project panel.

Step 2: Drag your audio file to the timeline.

Step 3: Slide the playhead to where you want the audio to start creeping in. This is the beginning of our fade-in.

Step 4: Click on the stopwatch next to Audio Levels to drop a keyframe.

Step 5: Move the playhead to where you want the audio to be fully audible. Add a second keyframe.

Step 6: For the fade-out, decide where you want the audio to start its descent into silence and drop a third keyframe.

Step 7: Now, slide to where you want the audio to go completely quiet. This creates your fourth and final keyframe.

Step 8: Click on Waveform to reveal a visualization of your audio. Now, lower the Audio Level values of your first and last keyframes until the visualizer shows the sound is no longer audible.

You can also increase the Audio Level values of your second and third keyframes up to +12.00dB.

Step 9: Hit play and listen. If it sounds off, you can always drag the keyframes around to adjust the fade duration.

Tips for Better Audio Manipulation

Before we wrap up, let’s dive into some pro tips to elevate your audio editing skills in After Effects:

  • Different Fade Lengths: The length of your fade can change the feel of a scene. A quick fade might feel abrupt, perfect for sudden transitions or changes in mood. On the other hand, a slow, lingering fade can give a sense of closure or melancholy.
  • Layering Sounds: Remember, audio is all about layering. Sometimes, fading one sound while introducing another can create a beautiful audio landscape.
  • Ambient Sounds: Add background noises like birds or traffic. They fill gaps and make your audio feel real.

And that’s a wrap! We’ve covered everything from the basics of importing your audio into After Effects to the nitty-gritty of keyframe manipulation for perfect audio fades.
