About JG Volume Booster

JG Volume Booster lets you amplify any Chrome tab's volume well beyond the system limit, up to 600% of the original. How it works The extension captures the active tab's audio stream via the `tabCapture` API, then processes it in an offscreen document using the Web Audio API. Sound is amplified in real time, entirely inside your browser, with no external transmission. What you can do - Boost a single tab's volume up to 600% without affecting others - Choose from three audio presets: Default, Voice (mid-range boost for podcasts and calls) and Bass (for music) - Jump instantly to 50%, 100%, or 150% with one click - See all currently playing tabs and their volume levels at a glance - Switch between light and dark theme - Each tab's setting is remembered across sessions What the extension does not do - It does not collect any personal data - It does not track your browsing - It does not communicate with any external server - Everything is stored locally in your browser Made by justgeek.fr
