These knobs move the module's published schema, but the preview engine only renders a few modules so far — OSC Mini, FX Mini, Amp Rig, Space Mini and the OSC-1 chain — so they won't change what you hear yet.

Reverb

A room, approximated cheaply.

A stage of OSC-1. It works the same on its own page as it does in the chain — same parameters, same paths.

About

A simple algorithmic reverb - room size, damping, wet - at the end of the chain where a room belongs. Not a convolution, and not pretending to be one.

Take it into your DAW.

Same DSP as this page. The plugin isn't a rebuild — it's the identical kernel from the identical TypeScript source, compiled native instead of to WASM.

Free forever, no account, and playing it in the browser will never ask you for one. VST3 and standalone today; AU and CLAP are on the roadmap.

How it works.

The preview builds a decaying noise impulse response from Room Size and Damping and convolves the wet path against it, in parallel with the dry path. Changing Room Size or Damping regenerates the impulse and swaps it in.

This is the cheapest honest reverb there is, and it is not the algorithm Space Mini will ship. Room Size maps to tail length and Damping to a low-pass on the tail; there are no early reflections and no modulation in the tail.

It's yours to read and to fork.

npx codex clone reverb-stage
npm run dev

The codex CLI name is proposed, not shipped. That command gives you this module's DSP, schema, presets and UI as a local project — change a number, hear it immediately.

Goes well with.
