Volume Booster Pro από Alican Öztürk

Volume Booster amplifies your browser audio up to 1000% with precision controls. Adjust volume with a slider or preset buttons, enhance bass with a +15 dB low-shelf filter, fine-tune stereo balance, and merge channels into mono for clearer playback. A built-in compressor prevents distortion at high levels.

Apply settings per-tab, per-site, or globally. Saved configurations persist across sessions, and you can manage all site-specific settings from the popup menu. Works with HTML5 video and audio elements, including dynamically loaded media in single-page applications.
