✔ Bass Booster – rich low frequencies for deep sound
✔ Quick access – switch to any audio-playing tab with one click

Full-Screen Mode:\t

Browser does not allow full-screen mode when using extensions that modify sound. That’s why you will always see a blue indicator on the tab bar, signaling that audio is being processed. This is a built-in security measure.

Tip: To hide the browser interface, press F11 (Windows) or Ctrl + Cmd + F (Mac).

Permissions Explained: “Read and change all your data on the websites you visit” – required to connect to AudioContext, manage sound, and display a list of audio-playing tabs.
