Volume Booster

Boost the audio of the current tab up to 600%, with a built-in limiter to reduce distortion.

Some videos, meetings and lectures are recorded far too quietly. Volume Booster amplifies the audio of the tab you are on, up to 600% of its normal level, with a simple slider. FEATURES • Slider from 100% to 600%, plus one-click 150% / 200% / 300% presets • Built-in soft limiter, so heavy boost sounds loud rather than distorted • Per-tab: boosting one tab never changes the others • Instant reset back to 100% • Light and dark popup, matching your system theme • No account, no sign-in, no ads HOW IT WORKS Chrome offers no way to set a tab's volume directly, so the extension captures the audio of the tab you choose and passes it through a Web Audio gain stage and a limiter before playing it back. Nothing is recorded, stored or transmitted — the audio never leaves your computer. PRIVACY This extension collects no data whatsoever. No browsing history, no personal information, no analytics. NOTE Boosting is real amplification. Above roughly 200% on already-loud audio you may still hear distortion, and sustained high levels can be hard on small speakers and on your hearing. Start low and raise it only as far as you need. Audio capture is blocked by Chrome on chrome:// pages and the Chrome Web Store, so the extension cannot work on those.
