Increase volume above maximum for all tabs even if the volume level in system set on maximum.
Now you are not limited by the maximum amplification capabilities of your PC’s sound card. You can raise volume to the desired level even if the volume level in system set on maximum. Volume Booster processes all audio that is being played in browser and boosts it before it gets to the sound card.
Features:
Chrome prevents you from going to a complete full-screen when using any extension manipulating with sound so you can always see the blue rectangle icon in the tab bar (to be aware of audio is being manipulated). There’s no way to bypass it and after all it’s a good thing that keeps you safe. However you can improve the situation a bit by pressing F11 (on Windows) or Ctr+Cmd+F (on Mac).
