Volume Booster — Tab Audio Amplifier

Description

Turn quiet tabs up to 600% with one slider. Fullscreen keeps working, and a built-in limiter keeps loud audio clear. 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%, marked at every 100%, plus one-click 150% / 200% / 300% presets • Fullscreen keeps working while boosted • 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 FULLSCREEN Most volume boosters amplify a tab by capturing it, which stops the page going fullscreen. This one adjusts the video and audio on the page itself, so you can turn a quiet lecture up and still watch it fullscreen. A few sites keep their audio somewhere a script cannot reach; there the extension falls back to capturing the tab, and the popup tells you when that has happened. HOW IT WORKS Chrome offers no way to set a tab's volume directly, so the extension passes the page's own video and audio through a Web Audio gain stage, a limiter and a soft saturation stage before they reach your speakers. 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. Chrome does not allow extensions to run on chrome:// pages or the Chrome Web Store, so the extension cannot work on those.
