Overview

Music Light is an audio-reactive lighting and object scaling tool for Unity.

Add a component to a Light or GameObject, assign an AudioSource, and your scene starts pulsing to the beat — without animations, timelines, or manual keyframing.

You can quickly create effects from the Unity menu:

Window → Music Light → Add Beat Light
Window → Music Light → Add Beat Scale

Press Play and see the result immediately in Play Mode.

Music Light is designed to react smoothly to music, not to shake or flicker like a raw FFT visualizer. It uses an envelope-based response with fast attack, slow decay, noise gate, and smoothing, so lights and scale changes feel more like controlled club lighting instead of a noisy audio spectrum.

The package includes fine control for both lights and objects:

Lights can react through brightness, color, gradients, and strobe.
Objects can react through uniform scale or per-axis scale.

Four frequency bands are available:

• Bass
• Mid
• Treble
• Full

Use bass for strong beat-driven pulses, treble for lighter flicker-style motion, or full range for general music response — without manually tuning every track.

Music Light also includes an extensible MusicReactor API.
