DeckBeam drives a standard projector like a laser rig — fanned beams and sweeps that read as real lasers once there's haze in the air, reacting live to every kick and snare. No laser diode to certify, no lighting truss, no mixer feed. Just your phone, a projector, and some fog.
How it works
No accounts, no calibration, no mixer cable to run across the booth.
Plug into a projector over HDMI, or send it wirelessly with AirPlay. A little haze or fog in the room is what turns the beam patterns into a real laser look.
Choose from 9 built-in audio-reactive patterns, or drop in your own photo or GIF — a logo, an event flyer, whatever fits the night.
DeckBeam listens through the mic, picks out kicks, snares, and hats in real time, and drives the visual live on both screens at once.
Features
One phone. No mixer feed, no laptop, no extra gear to carry in.
Spectral-flux onset detection picks out kick, snare, and hat transients from whatever's playing in the room — no mixer feed or BPM tap required.
Drive a projector over wired HDMI or wirelessly with AirPlay. The beam effect comes from haze in the air, not a laser diode — no Class 3B/4 hardware, no certification.
Scanner, Derby, Laser Burst, Moonflower, Polygon, RGB Spot, Raindrops, Snowstorm, and Spinner — each modeled on a real disco or laser fixture, reacting to the beat differently.
Import a logo, flyer, or animated GIF from your library and DeckBeam drives it just like a built-in pattern — brightness and motion react to the beat.
Let patterns auto-rotate every 60 seconds, or lock to one manually. Auto-dims on silence so nothing flashes awkwardly between tracks.
Beat detection, rendering, and the external display all run entirely on-device. No login, no cloud dependency, nothing to configure before doors open.
Built-in patterns
Named after the real disco and laser fixtures they emulate. Switch anytime, mid-set, without missing a beat.
The trick
Run a projector through haze or fog and its light stops being a flat picture on a wall — it becomes visible beams cutting through the room, the same way a real laser rig reads. DeckBeam's patterns are built around that trick: Scanner, Derby, Laser Burst, Moonflower — each modeled on a real disco or laser fixture, fanned and swept live to the beat. No laser diode means no Class 3B/4 hardware, no venue laser certification, no safety interlocks to manage.
Dual output
Your phone shows a private control panel and live preview — pick patterns, check levels, adjust settings. The external display only ever shows the full-screen visual, so the crowd never sees your UI.
Beat detection
DeckBeam separates kick, snare, and hat transients using spectral-flux onset detection, the same category of analysis real beat-tracking tools use. Patterns respond to what's actually in the mix, not a simple loudness threshold.

FAQ
Everything DJs ask before their first set with DeckBeam.
No. DeckBeam listens to the room through your phone's built-in microphone, the same way a person would. There's no cable to run from a mixer, no audio interface, and nothing to configure in your DJ software — if the music is audible in the room, DeckBeam can react to it.
No. DeckBeam is designed to run through a standard video projector, not a laser. Its patterns are built to read as laser-style beams once there's haze or fog in the air catching the light — no laser diode, no Class 3B/4 hardware, and none of the venue certification or safety interlocks a real laser rig requires.
For the full beam effect, yes — haze or fog in the air is what makes a projector's light visible as cutting beams rather than a flat image on a wall. A small haze machine is enough; you don't need heavy theatrical fog. Without haze, DeckBeam's patterns still display normally, just as a projected visual rather than beams in the room.
Any external display your iPhone or iPad can drive — a projector over wired HDMI or wirelessly over AirPlay is what gives the laser-beam effect through haze, but DeckBeam also works with a regular TV as a straightforward audio-reactive visual. The same output plays on your phone's live preview at once.
Yes. Alongside the built-in procedural patterns, DeckBeam can import any photo or animated GIF from your library and drive it the same way — brightness and motion react to the beat just like a built-in pattern.
No. Beat detection, pattern rendering, and the external display output all run entirely on-device. DeckBeam makes no network requests during normal use.
DeckBeam uses spectral-flux onset detection tuned for kick, snare, and hat transients — the same category of signal processing used in real beat-tracking tools, not a simple volume threshold. It's built to react to what's actually playing, not just get louder and quieter.
DeckBeam requires iOS 17.0 or later. It's built for iPhone and iPad, and supports external display output over wired HDMI (confirmed on iPad) and AirPlay.
