Spectrum 4D extends the classic frequency bar visualizer with a fourth dimension — time. As the track plays from 0% to 100%, the bars' physical arrangement evolves (arching into a dome, spiraling, crystallizing) while still reacting beat-by-beat to audio amplitude. Use evolutionSpeed to control how quickly the topology changes.
Key Features
Parameters
| Parameter | Description | Range / Options |
|---|---|---|
| 4D Mode | grow-dome / collapse-flat / chorus-bloom / spiral-rise / freeze-crystal / wave-arch | Select |
| Bar Count | Number of frequency bars | 8–128 |
| Evolution Speed | Rate at which the topology evolves | 0.1–3.0 |
Tips & Best Practices
- 1
grow-dome starts subtle — let it play for 30+ seconds to see full effect.
- 2
freeze-crystal is great for tracks with a big finale.
- 3
chorus-bloom combined with a BPM of 128+ creates satisfying visual explosions.
Export Performance
4D engines are CPU-bound during topology transitions. Keep Bar Count under 80 for 60fps on mid-range hardware.
