Beyond the Snore: Real-time Sleep Apnea Screening with OpenAI Whisper and PyTorch

Snoring is often treated as a late-night punchline, but for millions, it’s a symptom of Obstructive Sleep Apnea (OSA) - a serious condition where breathing repeatedly stops and starts. As developers, we have the tools to turn a smartinto a diagnostic-grade monitor. In this tutorial, we are diving deep into Audio Signal Processing and Deep Learning to build an OSA screening tool. We’ll leverage OpenAI Whisper for robust audio denoising, Librosa for feature extraction, and a fine-tuned PyTorch CNN to classify breathing patterns.
