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:

笔记:
▔▔▔▔▔
1.由于在不同的设备麦克风限制米范围是不同的,通常规模的低端不能因为麦克风噪声和刻度的上端的实现是通过在高的水平的麦克风失真的限制。
2.采用AGC(自动增益控制)的设备无法通过这个程序可以自动禁用将有显著测量误差和有限的范围内。这不是应用程序的故障。
3.如果有测量问题,或者根本不工作,请尝试禁用设置“使用高采样率”,重新启动设备并重新校准。
