## What it is
Reaktion is an audio reactive animation toolkit for Unity, providing components that drive animations from audio input. It was developed by Keijiro Takahashi and last released in 2015.

## Use cases
- make Unity scenes react to music
- animate objects to audio beats
- build audio visualizers in Unity
- sync game animations with sound
- create generative audio-driven motion graphics

## When to choose
- you need audio-reactive animation in Unity and are on an older Unity version
- you want a lightweight MIT-licensed toolkit to adapt for beat-synced visuals

## When to avoid
- you need actively maintained or updated tooling for modern Unity versions
- you need audio reactivity outside of Unity

## Facets
- artifact type: library
- maturity: abandoned
- function: animation, audio-processing
- domain: graphics
- platform: game-engine
- tags: unity, audio-reactive, music-visualization, game-development, audio
