CAIRN is a reverb built from twenty-five measured places.
A reverb that simply sounds good. Twenty-five real places instead of an algorithm — a cathedral, a 5,000-year-old tomb, a reactor hall, measured on site. And a room you can move around your head, by hand or by automation.
For anyone who wants a room with a name, a date and a measurement behind it. No Windows, no AAX, and no plate or spring emulations.
Put the room behind you
Every curve is measured. The ring is the room's real decay, the handles are the EQ, the flower is your signal. Drag anything.
Move the room, not the knob. Put the space anywhere around your head — behind, above, circling — and automate the path. On headphones the reverb travels while the dry signal stays put.
Two places at once. Blend a tomb into a cathedral, or let CAIRN travel through all twenty-five on its own.
Hold it forever. Freeze keeps the tail as a cloud that never drifts; Bloom gives a recording the life of an algorithm.
Hearing is the whole argument
The shipped impulse response, 35 % mix, nothing else. What you hear is the room.
Twenty-five places, zero latency
Controls, rooms and installation are in the manual.
Manual (PDF)A serial, not a leash
The serial is a calculation over your email address, not a key on a server — so nothing has to be switched on for the device to run, and nothing can be switched off. The full rule, including why prices here never drop after launch, is on one page.
Pricing policyTen dollars, once
No trial clock, no crippled version. Twenty-five rooms took a lot of measuring and a lot of listening; ten dollars is what that is worth once, not every year. macOS (Apple silicon + Intel), AU and VST3, not yet notarised — the manual explains the one click that takes on first launch.
If you have never used anything of ours, start here. HALO is a complete reverb for Ableton, costs an email address, and holds nothing back — same build, same measurements, same licence rules as the device on the right.
