Creating an Audio Waveform in After Effects

Introduction

An animated audio waveform is a great way to visualize sound in After Effects. It can be used for music videos, podcasts, or any other audio-based content. In this guide, you will learn how to create a dynamic audio spectrum using built-in effects.

Step 1: Create a New Composition

Open After Effects and create a new composition by going to Composition > New Composition. Set the resolution, frame rate, and duration according to your project needs. Step 2: Import Your Audio File

Go to File > Import > File and select your audio file. Drag and drop it onto the Timeline to use it in your composition.

Step 3: Create a Solid Layer

Go to Layer > New > Solid and choose any color for the solid background. This layer will be used to generate the audio waveform effect. Step 4: Apply the Audio Spectrum Effect

With the solid layer selected, go to the Effects & Presets panel and search for Audio Spectrum. Drag and drop it onto the solid layer to apply the effect.

Step 5: Adjust the Effect Settings

In the Effect Controls Panel, customize the settings:

• Audio Layer: Select your imported audio file.
• Start and End Points: Adjust the position of the waveform.
• Frequency Bands: Increase this value to add more detail.
• Maximum Height: Adjust the height of the waveform.
• Display Options: Choose Digital or Analog Lines for different styles.

Step 6: Add a Glow Effect (Optional)

To enhance the look of the waveform, go to the Effects & Presets panel, search for Glow, and apply it to the solid layer. Adjust the intensity and radius for a soft glow effect.

Step 7: Preview the Animation

Press Spacebar to preview your animation and check if the waveform responds correctly to the audio.

Step 8: Render Your Final Animation

Once you are happy with the animation, go to Composition > Add to Render Queue, adjust the settings, and render the final video. Conclusion

Creating an audio waveform in After Effects is a simple yet effective way to visualize sound. With custom adjustments and effects, you can enhance the visual appeal and make it fit your project’s style.
