Turn up the sound of any tab past 100%, all the way to 600%, or turn it down, mute it, and shape it with a simple bass, mid and treble equaliser. A limiter keeps loud parts from crackling.

✨ What it does
- Volume from 0 to 600% for each tab, with a slider and quick buttons (50%, 100%, 200%, 300%, 600%).
- Limiter on the boosted sound, so loud parts are held back instead of clipping and crackling.
- Mute the tab with one click.
- 3-band equaliser: bass, mid and treble from -12 to +12 dB, with presets for Voice (clearer speech) and Bass boost.
- Live level meter, so you can see the sound coming through.
- Playing sound list: every tab making sound, with its level. Mute any of them from the list, or click one to go to it.
- Badge on the icon with the tab's level, for example 300%.
- Remember for this site: the next time you open VolumeGeek on that site, it puts your level and equaliser back.
🚫 What it won't do
- It only changes a tab after you click the VolumeGeek button on it. Browsers don't let extensions take a tab's sound without that click, and that is a good thing.
- Remembered levels come back when you open VolumeGeek on that site, not by themselves, for the same reason.
- It can't change browser pages (settings, the add-on stores).
- Firefox: Firefox has no tab capture, so VolumeGeek changes the page's audio and video players instead. Sound made another way (games and web apps that build their own sound) isn't changed. Sound loaded from another site that doesn't allow it (no CORS) can only go up to 100% there, and the menu says so. VolumeGeek never sends that sound through the booster, because the browser would make it silent.

Chrome, Edge, Brave, Opera and Vivaldi
- Unzip the download somewhere you'll keep it.

Build it yourself
The code in this repo covers both versions. manifest.json is the Chromium manifest and manifest.firefox.json is the Firefox one. Run ./build.sh to make every package in dist/.
🧭 How to use
- Open the tab that is too quiet (or too loud) and click the VolumeGeek icon.
- Drag the slider, or press one of the quick buttons. The level shows on the icon.
- Pick Voice or Bass boost, or move the bass, mid and treble sliders yourself.
- Press Mute to silence the tab, and Reset to put it back to normal.
- Tick Remember for this site to keep the level and equaliser for that site.
⚙️ How it works
- Chrome, Edge and other Chromium browsers:
capture.js takes the tab's sound with tabCapture when you change it, and offscreen.js plays it through a hidden extension page. Setting a tab back to 100% with the equaliser off lets the tab go again, so it plays as normal.
- Firefox:
fx.js is added to the tab you are on when you use VolumeGeek. It sends the page's audio and video players (also ones added later and ones in same-site frames) through the same sound chain. It checks where each sound file comes from first, and leaves sound from other sites without CORS on plain player volume.
chain.js is the sound chain both use: bass, mid and treble filters, the volume, then a limiter. Two meters, before and after, drive the level display.
🔒 Privacy
VolumeGeek has no account, no analytics and sends nothing anywhere. The sound never leaves your computer: it is changed in your browser and played straight back to you. Nothing is recorded or saved. The only things stored are the levels you set, in your browser's memory until it closes, and the sites you ticked Remember for, on your own computer.
