Step-by-Step Guide
First, open Adobe After Effects and create a new project. This is the first step to realizing your creative vision. Have the MP3 file that you want to animate already downloaded beforehand, as you will import it later.

To import your audio file, navigate to "File" > "Import." Choose the MP3 file from the course materials and add it to your project. Then, drag the audio file onto the timeline so you can use it for animation.
Now that the audio file is in your project, you can begin working. First, listen to the file and identify the desired beats you want to animate. It is important to know exactly which parts of the music you want to translate into visual animations.
Once you have identified the beats, it's time to work with expressions. This allows you to automatically control and link parameters. Choose an element in your composition that you want to animate, such as a shape or text. Press 'Alt' and click on the stopwatch icon next to the property you want to animate to open a text field for the expression.
In the expressions box, enter a simple command that responds to the audio file, such as "loopOut()" to achieve a continuous effect. Experiment with different commands to achieve the desired result. Here, you have the opportunity to generate extremely creative animations.
Now it's time to refine your animations. Play around with the keyframes and various effects of After Effects. Make the animation dynamic and eye-catching. Also, use color adjustments and motion effects to intensify the connection to the music.
If everything looks good, the final step is to render and export your animation. Navigate to "Composition" > "Add to Render Queue." Choose the desired output settings and location. Soon, you will have your finished product in hand - a creative animation that captures the essence of your audio file.
Summary
In this step-by-step guide, you have learned how to visually animate an audio file with Adobe After Effects. From the initial import steps to applying expressions and refining the animation, you have all the necessary foundations to reflect your music with creative effects.
