SuperchargeAudio — Volume, EQ, and Spatial Controls for Every Tab
SuperchargeAudio brings granular audio control to every browser tab. Boost volume beyond the browser's 100% limit, shape sound with a 10-band equalizer, and widen or narrow the stereo field — all without leaving the browser. Smart mute keeps background tabs silent while you focus on the active one, and per-site memory means your preferred settings apply automatically every time you return to a site. For DRM-protected streaming sites where in-page audio processing is not permitted, an optional tab-audio-capture mode applies the same controls to the tab's output.
