Field notes
The settings expose A, C, and Z weighting, with fast, slow, and impulse response options. Calibration is a manual comparison: the page instructs users to place the device beside a calibrated meter, play a steady sound such as pink noise or a 1 kHz tone, and enter the reference reading. It describes CSV logs as second-by-second records and says the audio is analyzed on-device.
