About this extension
This is a simple Chrome extension I put together to give you more control over your browser's audio and video. If you've ever felt like a video was too quiet even at 100%, or if you wanted to fly through a long lecture without clicking menus, this is for you.
Volume Boost (Up to 500%): Sometimes 100% just isn't enough. This uses the Web Audio API to crank things up to 5x the normal volume. Great for quiet laptop speakers!
Insane Speed Control: You can go anywhere from 0.1x (super slow) to 16x (super fast). It's a smooth slider, so you aren't stuck with just the standard presets.
Per-Tab Customization: Each tab is independent. You can boost a video in one tab while keeping music at a normal level in another.
On-Video Controls: Instead of clicking the extension icon every time, a small badge appears right on the video player. You can tweak everything from there.

  • 100% Open Source: You're free to check out the code link, fork it, and make it your own.
  • Your Data Stays Yours: I don't collect, store, or transmit any of your browsing data, history, or personal info. Everything happens locally in your browser. No trackers.
