SoundLog: Decibel Sound Meter

SoundLog turns your smartphone into an accurate sound level meter, decibel (dB) reader, and noise monitor. Measure ambient noise levels in real time, record sound sessions with detailed statistics, and export professional PDF reports whenever you need proof or documentation.

Why Choose SoundLog?
Unlike standard sound meter apps that stop when you lock your screen or switch apps, SoundLog features continuous background monitoring. Whether you need to document neighborhood noise complaints, assess workplace sound exposure, or monitor the nursery while your baby sleeps, SoundLog captures every decibel accurately.

🎯 Key Features:

• Real-Time Sound & Decibel Meter: Fast, responsive dB gauge displaying live sound pressure levels (SPL) with an intuitive wave chart.

• Export Professional PDF Reports: Generate detailed noise reports with session notes, timestamps, average (Avg), minimum (Min), and peak (Max/Peak) decibel levels with a single tap. Perfect for landlord or municipal noise disputes.
• Microphone Calibration: Calibrate your device against a reference meter (±15 dB) to compensate for hardware sensitivity differences.
• Noise Level Reference Guide: Instantly understand what your readings mean with real-life sound references (Quiet Room, Whisper, Normal Conversation, Busy Traffic, Hazardous Noise).
• Measurement History & Archive: Save, review, and manage all your past acoustic sessions securely on your device.
• Battery-Friendly Dark Theme: Clean, modern dark mode interface designed for clear visibility and low battery consumption during long sessions.

🔍 Common Use Cases:

- Neighbor & Neighborhood Noise: Document persistent disturbances, loud music, or late-night construction noise with timestamped PDF evidence.
