muril (murmur + ‑il) is a minimal CLI that plays brown noise through your default audio output. Stop with Ctrl+C.
- Node.js 18+
- macOS (x64 / arm64), Windows (x64 / arm64), or Linux (x64 / arm64) with a working default audio device
Audio output uses @echogarden/audio-io (prebuilt native addons, no compiler toolchain needed at install time).
The package is published on npm as @skelogh/muril (scoped name required by the registry). The CLI command is still muril.
npm install @skelogh/murilnpx @skelogh/murilThat runs the muril binary from the package (no global install required).
Options: --volume <0-1> sets the starting level (default 1). -v / --version prints the package version.
Interactive (terminal only): while running, ↑ / ↓ adjust volume in steps of 5%. Ctrl+C stops playback. If stdin isn’t a TTY (e.g. piped), only --volume applies and there are no key controls.
After a global install, you can run:
murilgit clone https://github.com/SkeloGH/muril.git
cd muril
npm install
npm run build
npm test
node dist/cli.jsTo use the muril command name locally: npm link in this directory, then run muril.
