Sound Control

Boost sound volume or lower the sound of specific browser tabs when you install this extension. Quiet podcasts, lecture recordings, and indie game streams often ship with track levels well below broadcast standards. Pumping your system volume to 100 % helps that tab—then leaves everything else painfully loud. Because Sound Control reroutes every Unlike some “volume booster” apps that proxy streams through external servers to normalize loudness, Sound Control does all processing locally with the built-in Web Audio API. There are no network permissions, no trackers, and no telemetry. Even offline files opened in the browser get the same treatment, making the extension safe in bandwidth-constrained or privacy-sensitive environments. Sound Control adds virtually no startup overhead. UI minimalism—one vertical slider, a numeric badge, and a reset shortcut (double-click or “R”)—means most users master it in seconds. There’s nothing to configure, no accounts, and no hidden menus.
