Notes:
▔▔▔▔▔
1. Due to microphone limitations on different devices the meter range is different, usually the low end of the scale cannot be achieved because of 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) that cannot be automatically disabled by this app will have significant measurement errors and limited range. This is not app's fault.

3. If you have measuring problems or doesn't work at all, try to disable "Use high sampling rate" in settings, restart the device and recalibrate.

4. Calibration procedure and other information can be found here:

Recently changed in this version

V2.7 changes: New measuring algorithm and headroom (range) extension option enables much more measurement range, transforming this app into a serious professional measuring equipment. Also added is a new meter layout and very useful configurable time weighted average (TWA) display. Users, please check predefined calibration selection in Prefs and for those who made custom calibration please recalibrate again!

    Works well enough but loses two points for ugly and useless advertising. Totally destroys the slick appearance of the app, which was what attracted me in the first place. Sigh.

    The calibration for my Samsung Galaxy Victory 4G LTE is about 0.75.
