FAAH Error Sound is a simple macOS-first VS Code extension that plays a bundled FAAH sound when the currently active file gains a new error diagnostic.
What it does
Watches only the active editor
Reacts only to Error diagnostics
Plays sound only when a new error appears in the active file
Ignores warnings, info, hints, and background files
Avoids repeating the sound when the same error is re-published
Commands
FAAH Error: Test Play Sound
FAAH Error: Show Debug State
How to test
Open a JavaScript or TypeScript file.
Introduce a real syntax or type error in the active file.
Wait for the red error diagnostic.
The FAAH sound should play once when the new error appears.
Example test input:
const x =
Notes
This version is macOS-only and uses the built-in afplay command.
The bundled sound file is included inside the extension package.
The extension only reacts to the file currently open in the active editor.
Development
npm install
npm run compile
