Average level, Leq, and Lmax measurements
Clear sound-level ratings
Live sound-level charts
Automatic peak-event detection
Seek and replay audio around loud events
Save recordings or decibel data only

Privacy Mode stores only sound-level charts and statistics without retaining playable audio. Recordings and measurements are stored locally on your device.
