REACT by Compeller transforms any audio into stunning, mathematically-generated visuals. No loops. No timelines. No cue stacks. Just pure, audio-driven reactive visuals that respond to every beat, every frequency, every moment.
Everything you need to create mesmerizing visuals that move with your music.
Multi-band frequency analysis with advanced beat detection. REACT listens to your audio and extracts meaningful data—bass hits, mid-range energy, high-frequency detail, and precise beat timing—all in real-time with sub-frame latency.
No pre-rendered loops or video clips. Every visual is generated mathematically in real-time based on audio input. This means infinite variation—the same song never looks exactly the same twice, but always feels perfectly synchronized.
NDI, Spout, DMX, and MIDI outputs let you integrate REACT into any professional workflow. Send visuals to LED walls, control lighting rigs, trigger external effects, or stream directly to broadcast systems.
Plug in a microphone, route system audio, connect to a DJ mixer, or use virtual audio cables. REACT doesn't care where your audio comes from—if you can hear it, REACT can visualize it.
No timelines to program. No cue stacks to manage. No frame-by-frame editing. Just connect your audio and go. REACT automatically creates stunning visuals that respond intelligently to whatever you're playing.
Choose from a library of visual engines or create your own. Each engine responds to audio in unique ways—particle systems, geometric patterns, fluid simulations, and more. Stack and blend for endless creative possibilities.
Traditional VJ software requires hours of preparation. REACT works the moment you press play.
Hours spent collecting, organizing, and cueing video clips that may or may not match your music.
Visuals are created mathematically, frame by frame, responding to your actual audio—not generic beats.
Constantly clicking buttons, adjusting faders, or programming complex cue stacks during performance.
Set it and forget it—or take control when you want. REACT adapts to your workflow.
Every visual element responds to your audio frequencies
From bedroom DJs to stadium festivals, REACT scales to any venue.
Add instant visual impact to your sets without hiring a VJ. REACT syncs to your mixer output and creates visuals that match your energy, transitions, and drops.

Everything you need to know about REACT.
Unlike traditional VJ software that relies on pre-rendered video loops, REACT generates all visuals mathematically in real-time based on your audio input. This means infinite variation, perfect synchronization, and zero prep time. Our patent-pending technology ensures your visuals are always unique and always in sync.
REACT works with any audio source you can route to your computer: microphones, line inputs, DJ mixers, audio interfaces, system audio capture, and virtual audio cables. If your computer can hear it, REACT can visualize it.
No programming required. REACT is designed for artists and performers, not developers. Simply select a visual engine, connect your audio, and you're ready to go. Advanced users can customize parameters, but it's completely optional.
REACT runs on Windows and macOS. For optimal performance, we recommend a dedicated GPU (NVIDIA GTX 1060 or better, or Apple Silicon). The software is optimized to run smoothly even on modest hardware for basic visual engines.
Yes! REACT is designed for professional use. All visuals generated by REACT are yours to use in any context—live performances, streams, recordings, or installations. There are no additional licensing fees or royalties.
REACT outputs via NDI (network video), Spout (GPU texture sharing), DMX (lighting control), and MIDI (device control). This means it integrates with virtually any professional AV system—from LED walls and projectors to lighting rigs and streaming software like OBS.
