Turn your MacBook into a squeaky door.
Every lid movement triggers a satisfying creak.
Requires macOS 13.0 or later · Apple Silicon
Free & open source
Drag the slider to hear the squeak
Reads the built-in AppleHID lid sensor at 60fps to detect the slightest movement.
Playback speed maps to lid velocity — slow creaks and fast snaps sound completely different.
Haunted door cracks, cat meows, alien whispers, whale songs, wind effects, and more. All generated in real-time.
No dock icon, no windows. Just a tiny menu bar icon to toggle, adjust volume, and pick sounds.
Under 1 MB. Near-zero CPU usage. Built natively in Swift with AVAudioEngine.
