I built a free open-source app that adds mechanical keyboard sounds system-wide on Windows

#windows #opensource #cpp #showdev

Hey DEV community! 👋

I just released MonkeySounds a free, open-source Windows app that plays
satisfying mechanical keyboard and mouse click sounds system-wide, for every
application on your PC.

Demo

Why I built it

I loved the browser extension that adds keyboard sounds while typing, but I
wanted it everywhere not just in the browser. So I built a native Windows
app in C++ that hooks directly into the input system.

What it does

🎹 Plays realistic mechanical switch sounds on every keystroke
🖱️ Plays click sounds on every mouse button press
🔇 Independent mute and volume control for keyboard and mouse
🎨 Ships with 16 built-in profiles (Cherry MX Blue/Brown/Black, Holy Panda, Alpaca, Typewriter, and more)
🛠️ Create your own profiles from any audio files with the built-in wizard
📦 Portable or installed your choice
⚡ Zero performance impact runs silently in the system tray

I built this because I wanted the satisfying mechanical keyboard sounds from the popular browser extension, but system-wide for every app on Windows, not just the browser. It's a lightweight tray app built in C++ with no runtime dependencies. Supports 16 built-in profiles (Cherry MX, Holy Panda, Alpaca, etc.) and lets you create custom profiles from any audio files. Happy to answer questions.
