This app helps you check if your phone’s microphone and speakers are working correctly by showing a live graph of the surrounding sounds. It listens to the audio input and displays the sound levels and frequencies in real time. However, the visual graph may only work on certain phones based on their audio processing capabilities. The app requests permission to use the microphone and updates the display smoothly if supported by the device.
