## What is Smart Noise Detector?

NoiseDetector is a smart recorder that automatically detects and records noise disturbances.

No need to keep a recorder running 24/7. NoiseDetector only records when sound levels exceed the ambient noise baseline. When the noise stops, recording stops automatically — saving your storage space.

【 FEATURES 】
• Real-time noise level (dB) monitoring
• Automatic ambient noise calibration at startup
• Adjustable threshold: +12dB / +18dB / +24dB above baseline
• Auto-start recording when threshold exceeded, auto-stop after 2s of silence
• Individual m4a files per noise event (minimal storage)
• Play and manage recordings in-app
• Intuitive real-time dB meter UI
• Background audio support

【 PERFECT FOR 】
• Documenting noise complaints from neighbors
• Tracking nighttime noise patterns
• Checking if your pet barks while you're away
• Recording snoring during sleep

【 HOW TO USE 】
1. Launch the app and tap "Start Monitoring"
2. Wait 3 seconds for ambient noise calibration
3. The app automatically records when loud noise is detected
4. Browse, play, and manage recordings anytime

【 PRIVACY 】
NoiseDetector does not collect or transmit any user data.
All recordings are stored locally on your device only.
