Readings can be wildly different merely turning off and on again. Almost 20dB different. Inexplicable.

All seemed to work as expected though db was a bit lower than expected. However, starting and restarting the app seems to occasionally change the mic calibration/sensitivity. Without any change in the environment, most of the rime it will say about 30 db, but maybe every 4th or 5th off/on cycle it will read about 50 db instead of 30 (which is thought to be the more accurate value). So comparing readings between off on cycles will not be reliable and I do not have much confidence in the absol
