"playing audio at high volume can damage hearing or destroy speakers......." you have to accept this notification to use this app at own risk. Be aware when trying to use this setting. if you hearing the very low sound level of any audio and video file you can try this fuction. But you don't need to worry about this warning if you customize setting very carefully. follow my steps.
