CD Noise Meter

A compact and simple noise level meter. The app works with the device's built-in microphone. Once a measurement is started, the resting noise level is measured, and any sound signals exceeding this level are displayed on the screen. The noise level is indicated both on the display at the top and on the graph at the bottom. Depending on the measured signal level, in addition to the numerical values ​​on the display, the display's background color or brightness also changes. The program allows you to customize the range of displayed values ​​and perform calibration. For added convenience, screenshots can be saved to the gallery.
