Tab EQ — Parametric Equalizer

Tab EQ turns any tab into a studio-grade parametric equalizer, with a speed and video console that remembers every YouTube channel. Unlike the fixed 10-slider equalizers in most extensions, Tab EQ gives you a real, draggable frequency-response curve, the same interaction pro audio tools use. Grab a point, move it in frequency and gain, scroll to change its width, and hear the change instantly. Switch to TAB SPD for playback speed and picture adjustments. Perfect for podcast playback preferences. [FEATURES] - True parametric curve editor: drag nodes, double-click to add/remove bands, scroll for Q, or type exact values. Peak, shelf, high/low-pass and notch filters. - Live spectrum analyzer behind the curve, so you EQ what you actually see. - Volume boost to 600% for quiet tabs, with a built-in limiter + auto-preamp so loud boosts never distort. - Per-tab: every tab gets its own independent EQ and speed. - Per-site & per-YouTube-channel memory: save an EQ for a whole domain, or for a specific YouTube channel, and it auto-applies next time - even as you switch between videos on that channel. Plus genre presets and your own saved presets. - Video FX: Natural, Vivid, Night and Mono looks, or your own contrast, brightness and saturation, with instant Bypass and Reset. - Safe on major streaming services: Tab EQ never captures protected video. It equalizes the site's own player inside the page instead, and video effects stay off, so the picture never goes black. - Full theming: built-in Light, Dark and color presets, or customize every color by hex value and save your own theme. The whole interface, including the graph and knobs, recolors live. - Instant Bypass: compare your EQ against the original audio with one click, no dropout. - Flatten: back to neutral in one click. - Keyboard shortcuts, a full-screen editor, and one-click enable (it turns on when you open it on a tab). [PRIVATE BY DESIGN] - Requests the absolute minimum permissions - no browsing history, no host permissions, no standing access to any site. (On YouTube it reads only the current channel name, locally, to remember your per-channel EQ.) - 100% local - audio and theming are processed in your browser. No network requests, no accounts, no analytics, no ads. - Works in Chrome, Brave, Edge and other Chromium browsers. [About the "read and change all your data" permission] Chrome shows this warning for any extension that uses the tab-audio-capture API - it is not something we can turn off. But here is exactly what Tab EQ can and cannot do: - ✅ It receives the audio of a tab only after you click "Enable EQ" on that tab. - ✅ When you open it on a tab (or press a shortcut), it works on that tab only, until the tab leaves the site. It checks the page for protected video, sets the speed and video look you choose, and on YouTube reads the channel of the playing video so it can remember your settings per channel. - ❌ It cannot read the page's text, forms, passwords, cookies, or history. - ❌ It requests no website host permissions and adds no background page access. - ℹ️ On YouTube it reads the channel name of the active tab (via `activeTab`+`scripting`, no warning, no network) so it can remember your EQ per channel - nothing else on the page is used or stored. We deliberately chose tab capture over the "content script" approach that some equalizers use. Content scripts show a friendlier install prompt but actually get full read/write access to every page and break on many sites. Tab capture is the genuinely more private and more reliable design. [RELEASE NOTES] Version 1.1.0: - Made the UI nicer Version 1.2.0: - Added speed controls
