🎧 Microphone Setup Guide

  • Use headphones for live monitoring to avoid feedback/echo.
  • Typical starting point: Filter 50–80 Hz, Sensitivity 6–9.
  • Place the mic directly on skin and move slowly.

🔧 Troubleshooting

  • Use HTTPS or localhost, then allow microphone permission.
  • Reduce Sensitivity/Monitor Volume if you hear hiss or squeal.
  • Big spikes or 180+ BPM likely mean noise; the detector smooths it.

📍 Optimal Microphone Positioning

  • 18+ weeks: begin around/just below the belly button, sweep slowly.
  • 8–16 weeks: start lower, above the pubic bone, and sweep both sides.
  • If concerned or unable to detect, contact your healthcare provider.
