Disclaimer:

1. Due to microphone limitations on different android devices, the meter range is different, usually the low end of the scale cannot be achieved due to the microphone noise and the upper end of the scale is limited by the microphone distortion on high levels. 2. Devices employing AGC (Automatic Gain Control) will have significant measurement errors and limited range. This is not application’s fault.
