Audio Reactive Visuals in TouchDesigner: Low-Latency Workflow
Most tutorials stop at basic FFT mapping. This guide covers practical set design for clubs, streams, and festivals with stable frame timing.
Pipeline
- Audio input -> Analyze CHOP (band split + smoothing)
- Control layer -> normalized channels for bass, mids, highs
- Visual layer -> materials, particles, feedback, camera logic
- Output layer -> NDI/Spout routing and failover scene
Performance tips
- Use a dedicated control COMP for all mappings.
- Clamp aggressive peaks to avoid strobe overload.
- Save safe scenes for dropout recovery.
Try REACT for instant audio-driven visual output without node graph setup.
