SoundBooster — per-tab volume

Boost any tab past 100% with a limiter that keeps it clean. Per-tab dial, live meter, no crackle.

Some tabs are just too quiet. A lecture recorded on a laptop mic, a video call where one person sounds far away, a film mixed so the dialogue disappears under the music. Your system volume is already at maximum and it still is not enough. SoundBooster gives every tab its own volume dial, from silence up to 800% — eight times louder than the page was going to play. ── HOW IT WORKS ────────────────────────────────────────── Open the popup and you get one big dial. Drag the ring, scroll over it to nudge a few percent, or double-click to snap back to 100%. The ring lights up with the audio actually playing in the tab, so you can see the level move before you touch anything. The setting belongs to that tab. Turn a quiet video up to 300% and everything else you have open stays exactly where it was. ── LOUD, NOT DISTORTED ─────────────────────────────────── Turning digital audio up is the easy part. Doing it without turning it into crackle is the reason this extension exists. Everything above 100% runs through a limiter and a soft clipper before it reaches your speakers. Peaks are caught and rounded off instead of being squared into distortion, and every level change ramps over a few milliseconds rather than jumping, so nothing clicks or pops when you move the dial. Two paths are used, whichever the page allows. Normally the boost is applied to the page's own audio, in the page. When that is impossible — a cross-origin video, or a game with no media element at all — the extension captures the tab's output and replays it through the same chain. ── EVERYTHING ELSE ─────────────────────────────────────── • Per-site memory — set a site once and it comes back at that level next time. • Tabs view — see every tab that is playing or boosted, and reset them all at once. • Keyboard shortcuts — Alt+Shift+Up / Down / 0 / M work straight from the page, fullscreen video included, without opening the popup at all. • On-page readout — a small badge shows the new level and fades away. • Dark and light themes. ── PRIVACY ─────────────────────────────────────────────── Nothing is collected and nothing is sent anywhere. No account, no analytics, no tracking, no network requests of any kind. Your levels are stored by Chrome on your own machine and never leave it. Every icon, font and image ships inside the package. Free, with no paid tier and no ads. ── A NOTE ON YOUR EARS ─────────────────────────────────── Boosting raises everything in the signal, hiss and background noise included. 800% is genuinely loud. Start low, go up gradually, and look after your hearing and your speakers. Requires Chrome 116 or newer.
