Sugar EQ for Tabs

Apply Sugar EQ's 10-band candy curve to the audio of any browser tab.

Sugar EQ for Tabs brings the same 10-band candy-curve equaliser from the Sugar EQ Mac app to any browser tab — no native app required. Click the toolbar icon, hit POWER, and the tab's audio runs through the same tuning as Sugar EQ's SUGAR preset: a gentle smile curve, a little more bass and treble, a little less midrange, balanced so it isn't just louder. Switch back to SUGARFREE for a true flat bypass. The popup shows a live spectrum of what's actually playing, with the EQ curve drawn right over it — so you can see the shape being applied, not just trust that it's there. NEW: FULLSCREEN VISUALIZER. Press the expand button in the popup and the tab's audio becomes the front panel of an imaginary late-90s car stereo: a brushed metal faceplate with machined knobs and backlit keys, and up to fifteen glowing instruments — spectrum analyser, analog VU needles, stereo phase scope, level meters, oscilloscope, spectral history, EQ curve, a seven-segment clock and a scrolling display. It re-arranges itself to fit any window shape, and comes in blue, violet, green, ember (red/orange) and candy pink. Everything shown is measured from the audio you're actually hearing.

Drag the brightness knob around to set it, like a real pot; the clickable area is larger. - No new permissions, no network access, nothing new stored beyond display settings.
