About Kiln.

Mission

More finished music in the world.

Most songs never get finished. Not because the people making them lack taste, but because mixing is a wall of jargon, gear and second-guessing. Kiln exists to take that wall down.

Professional polish without the learning curve or the investment. Every plugin does one job, with a few big controls instead of a wall of numbers, and explains itself in plain words while you work. No gatekeeping: whoever you are, whatever you recorded on, the goal is the best version of what you've got, finished and out in the world.

Finish, don't fiddle

Big controls that do the right thing, and level matching so you hear the change, not the volume.

Learn as you go

Explain says what every control does and what it's doing to your track right now.

Built for real recordings

Quiet rehearsal takes, drums in every mic, cheap interfaces: that's who Kiln is for.

Honest and fair

No dongles, no always-online checks, no hype. Taste is yours; Kiln handles the fixable things.

Our story

Solving Real World Problems.

Kiln started in a rehearsal space. We are a heavy shoegaze rock band, and record our rehearsals on the gear we can afford. The songs felt huge in our ears. Listening back in Logic, they came back quiet and cloudy, and turning them up only made it worse. The drums were in every microphone, and every gate we used chopped the vocal unnaturally.

The professional tools we used could fix it, but each one came with a wall of controls, and the session usually ended before the mix did. Enter Kiln; one job each, a few big controls, and sound tuned for the music we actually make.

Then we went looking for what other people struggle with. We read through published surveys of hundreds of producers, mastering engineers' lists of what goes wrong, and years of forum threads. The same problems came up again and again: in those surveys, most people finish fewer than half the songs they start, mixes that sound great at home fall apart on a phone, low end turns to mud, vocals won't sit, drums bleed into everything, tired ears make bad calls. Every Kiln plugin solves one of those problems, and that mindset becomes the roadmap as well. As new challenges arise, we will work to provide simple, approachable solutions.

Why pottery? Making a record and making pottery are the same kind of work - rough material, shaped by hand, fixed where it cracks, then fired until it holds. So every Kiln plugin is named after a potter's tool or technique, and each one's page talks about the inspiration for the name.

How it's built

Trusted foundations

Written in C++ on JUCE, the framework behind a large share of today's professional audio plugins. Audio Unit and VST3, native on Apple M-series Macs today, with Windows and Linux on the way.

Checked on every build

Every plugin passes Apple's own Audio Unit validator on a real Mac, every time anything changes, before a build can reach you.

Tested like instruments

Twenty-five automated test suites put the sound engines through recordings modelled on real problems: drums in a vocal mic, a vocal recorded 20 dB too low, mains hum, a thin snare. Every claim on this site is a number a test checks.

Clean where it counts

Drive, saturation and clipping run oversampled, so they stay smooth instead of harsh. Glaze limits true peaks, so masters stay clean on every service.

Fair comparisons

Level matching is built in wherever a plugin changes loudness, so louder never fools your ears.

Light and quick

Low on CPU. Most plugins add a few milliseconds of delay at most; Caliper and Damper look ahead (about 50 and 80 ms), and your DAW compensates automatically.

Yours to keep

No dongles and no always-online checks. A small menu-bar app installs and updates everything.

Written with Claude Code

We designed every plugin, decided how it should sound and look, and tested it in our own sessions. The code was written with Claude Code, Anthropic's AI coding assistant, to that brief, and checked by ear and by test. What it cost, and what we give back →

Tuned in real sessions

Shaped on a working band's own rough recordings, then refined until the result is ready to release.

Ready for CLAP

CLAP is coming alongside Audio Unit and VST3: the open plugin format built for modern hosts like Reaper and Bitwig, with smoother automation and better use of every core in your computer. It's also the bridge to Windows and Linux.

Start to finish

The suite follows the order of a mix: prep every track, shape each part, add tone and space, then glue and check. Firing's checklist walks the song from rough to done, so each mix is built up the same way, one step at a time.
