Clear Wave Tune - Sonic Sound

This application offers users the capability to test the functionality of their speakers by generating specific sound wavelengths and tones. With a single click, the app automatically generates a clear sonic sound wave. Additionally, the app enables users to perform a stereo test to identify any issues with their speakers, such as muted or insufficiently loud output. Moreover, the application facilitates the generation of diverse sound waves with variable frequencies.

Furthermore, the app includes a built-in noise measuring feature that allows users to assess the loudness of their surroundings using a decibel meter. Simply by granting access to the speaker and pressing the start button, the app will display the loudness level of the environment.
