Quick answer

How does SlapWindows detect slaps using a microphone?

SlapWindows uses your Windows laptop's built-in microphone to listen for sudden loud impact sounds. It uses audio amplitude thresholding — when a sharp peak in audio volume is detected (typical of a physical slap), it triggers the sound pack. Normal background noise, typing, or talking stays below the threshold. You can adjust sensitivity from the system tray icon.
