// What it does
It listens to the room, and paints what it hears.
Luxaudica turns a screen you already own into part of the room. It takes the sound that is already playing, works out what the music is doing, and draws it live — all night, never twice the same, with nobody standing behind it.
What it does
It hears whatever is already playing
A Core Audio tap takes the whole output mix of the Mac, so a streaming set, a browser tab and a DJ app all arrive with no routing software in between. A microphone or line input covers a live band. With nothing playing at all, a built-in synthetic signal keeps the screen moving.
It follows the music, not a clock
Every frame it measures the beat and the tempo, the musical key and eight bands of spectrum, on the Mac. The picture answers the set that is actually being played, so there is no running order to keep it in step with and nothing to re-cut when the night changes shape.
It does not repeat, because nothing is a file
83 scenes are generated in front of the room, not played back at it, and 149 factory looks ship tuned and ready before anyone touches a control. The second hour does not match the first, and a regular cannot learn the loop.
It runs the night without anyone driving it
It opens on 3 questions — where you are, how it should feel, for how long — and builds the rotation from the answers. A timed session lands itself: it drifts to the room's calmer looks near the end and fades out. Open-ended, auto-pilot keeps evolving the look on its own.
It can be turned down for a public room
A Reduce flashing setting caps the per-beat strobe, and it is forced on for as long as the Mac’s own Reduce Motion setting is enabled. Every control carries a VoiceOver label, and the panel names the tab you are on in text rather than by tint alone.
It reports nothing, and keeps only what you record
The audio is analysed in memory, frame by frame, and is never sent anywhere. The one thing that puts it in a file is the recorder, and you start that: the movie it writes carries the audio alongside the picture, onto your own Mac. There is no advertising, and nothing is reported about you: the analytics SDK in the bundle ships switched off, with no project key and a master switch every reporting path checks first. It reaches the network for two things: a software update, and checking a licence key.
It goes on the screen you already have
Any display the Mac can drive, a second one as dedicated program output, and 10-bit Display P3 — with an HDR path where the panel has it. It records what it draws, in the sizes a phone expects.
What it replaces
What it costs not to have it
A screen with nothing on it is not neutral. Dark, it reads as closed. Showing a loop, it reads as something nobody has looked at since it went up. Showing a desktop, it reads as somebody's laptop. None of those is a disaster on its own, and all of them tell the person in front of it the same thing.
The alternative that actually works — booking someone to drive it — works for exactly as many evenings as you pay for. This one is bought once and is there the following Tuesday.
Which room is yours
There are 10 of them, grouped below under the front door each one belongs to, and every one names the room you pick in the app — so the first picture that comes up already suits what happens there. They are written from behind the counter, not from the product.
What ships with it
If you need the detail
Everything above has a mechanism under it, and it has its own page: the analysis that reads the beat and the key, the control surface, the retro output pass, on-device captions, the agent surface an LLM drives it through, and what it wires into — MIDI, OSC, timecode, multi-display.
