Smart Noise Detector

Smart Noise Detection Recorder

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.
