See live sound levels with a clean dark UI built for fast focus. Use A, B, C, or Z frequency weighting, watch min/max/average, and follow the real-time trend graph—ideal for quick checks at home, at work, or anywhere you need a dependable db meter.
Switch to Advanced mode for deeper insight: spectrum analyzer tools, spectrogram-style visualization (similar in spirit to tools like Spectroid), and TWA/Dose estimates so you can understand exposure over time—not just a single reading.
Save sessions, review history with playback and detailed stats, and export results as CSV, PDF, and WAV. Capture photos and videos with a live dB overlay to document inspections and reports. Calibration offset and manual audio input selection help you tune readings to your setup.
Decibel Meter is intended for awareness and comparative monitoring. It is not a certified professional SPL meter or laboratory instrument—readings depend on device hardware and microphone characteristics.
