Stop Ignoring Your Snore: Building a Real-Time Sleep Apnea Monitor with Whisper.cpp and Raspberry Pi

Ever wondered why you wake up feeling like a zombie despite "sleeping" for eight hours? Obstructive Sleep Apnea (OSA) is an invisible killer, a condition where your breathing repeatedly stops and starts during sleep. While professional sleep studies (polysomnography) are expensive and invasive, we can leverage Edge AI , Whisper.cpp , and the power of the Raspberry Pi to build a high-performance, privacy-first monitoring prototype. In this tutorial, we will dive deep into real-time audio processi
