Introduction

This is the result we will create, a Music Visualizer where spectrum bars dance to the music, a circle in the center pulses with every beat, and the night lights background also sync with the rhythm. Let's get started. Hello, welcome back to the complete Adobe After Effects series from Cerdas Inovasi Digital. This is the final project and the closing episode of this series, the Music Visualizer. We are creating an animation driven directly by the music, using real audio data. Create an 8-second Visualizer composition with a black background.

Step 1: Music and Background

Import the music beat audio onto the timeline, then the night lights footage as the background, with a Gaussian blur of 20 and opacity of 60% so it doesn't distract.

Step 2: Audio to Keyframes

Select the music layer, then Animation, Keyframe Assistant, Convert Audio to Keyframe. A null audio amplitude appears with a slider bot channel that has keyframes on every frame, large numbers when the music is loud, small when it's quiet. Create a solid spectrum, apply the Audio Spectrum, select the audio layer of the music beat, then set the start and end points horizontally below the screen, frequency bands 64, maximum height 400, and color Tosca to white.

Step 3: Audio Spectrum

The bars move according to the music frequency, change the mode to Add. Create a Tosca outlined circle in the center.

Step 4: Pulsing Circle

On the scale, type an expression that reads the audio amplitude slider, linear from amplitude 0 to 40 mapped to scale 80 to 130. The circle expands with every beat.

Step 5: Pulsing Background and Title

Also output the exposure lumetri on the background to the amplitude, so the city lights flash in sync with the music. Add a song title for the night rhythm in the center of the circle with a glow.

Step 6: Preview and Export

Play the preview with sound. All elements move precisely according to the music without any manual keyframes. Send to media encoder with the YouTube 1080p preset. We have transformed audio into keyframes, created an audio spectrum, pulsing circle and background with linear expressions, and exported for YouTube.
