Summary
A developer created a small app called 'stfu' that plays back audio it hears with a 2-second delay, designed to discourage people from playing loud content in public spaces. The idea came from frustration at Mumbai airport where someone was watching videos at full volume. The developer used Claude AI to generate a working version quickly. The app apparently works by creating an auditory feedback loop that makes people uncomfortable enough to stop the noise, though the developer admits not fully understanding the neuroscience behind it.
Key quotes
· 3 pulledi was at mumbai airport. some dude was watching reels on full volume and laughing loudly. asking nicely doesn't work anymore.
so i built a tiny app that plays back the same audio it hears, delayed by ~2 seconds. asked claude, it spat out a working version in one prompt. surprisingly WORKS.
something something auditory feedback loop something something cognitive dissonance. idk i'm not a neuroscientist. all i know is it makes people shut up
