Sound Booster — 音量を上げる 作成者: Vitalii Vasianovych

Say goodbye to low volume and hello to crystal-clear sound with Sound Booster. This handy browser extension lets you boost audio levels up to 600% on any tab, so you can enjoy videos, music, and more on YouTube, Vimeo, Dailymotion, and other platforms like never before.

Why You’ll Love Sound Booster:

Supercharge Your Sound – Go beyond default limits and amplify audio up to 600%.
Control Volume by Tab – Adjust sound levels separately for each tab.
Smooth Adjustments – Easily fine-tune volume with a simple slider (0% to 600%).
Simple and Easy to Use – Clean, intuitive design that anyone can master in seconds.

How It Works:

— Browsers sometimes limit sound-boosting extensions in full-screen mode. To keep you in the loop, a small blue indicator will show up on the tab bar when sound amplification is active.
— Quick Tip: Press F11 (Windows) or Ctrl + Cmd + F (Mac) to go full-screen without losing your boosted sound.

Hotkeys:

When the popup is open and active, you can use the following hotkeys to control volume:
• Left Arrow / Down Arrow – decrease volume by 10%
• Right Arrow / Up Arrow – increase volume by 10%
• Space – instantly boost volume by 100%
• M – mute/unmute

These shortcuts ensure quick and easy volume adjustments directly from the popup, giving you full control with just a keystroke.

Why Does It Need Permissions?
The extension needs access to website data to adjust audio settings using AudioContext and to show which tabs are playing sound. This helps it work smoothly and deliver the best sound experience.
