YouTube volume booster

About

This volume booster is designed specifically for YouTube, capable of drastically increasing webpage volume to 500%! Simply open the plugin on the video page, drag the slider, or click shortcut buttons like 50% or 200%, and the volume will instantly surge. When the volume exceeds 100%, the numbers and progress bar on the interface will turn a prominent orange, giving you a clear overview of the current status. A semi-transparent visual overlay will pop up in the center of the screen, providing real-time feedback on the current gain value, and will automatically fade away after 1.2 seconds, without interfering with your video viewing. Your browser will request permission to capture audio during use; simply grant this permission. All audio processing is done locally, without collecting any data. If you encounter any problems, the plugin includes a tutorial. Click the "Tutorial" button for detailed steps, and there's also a "Sample URL" button that leads directly to a test video for quick demonstrations.
