Shaker

Shakes the page in time with the bass of any audio or video playing in the tab.

SHAKER turns every tab into a visual subwoofer. It listens to the audio playing in your browser, isolates the bass frequencies, and shakes the page in real time with every kick, drop, and sub. Voice and mids are filtered out — only true low-end punches through. The result: YouTube concerts, music videos, livestreams, lo-fi mixes, and anything else with a beat suddenly hits a lot harder. — FEATURES — • Real-time bass detection (30–120 Hz kick/sub band) • Voice rejection — vocals, dialogue, and mids don't trigger the shake • Punchy attack + soft decay envelope, so kicks land and fade naturally • Adjustable intensity slider (mouse-wheel friendly) • One-click on/off toggle • Works on YouTube, and any site with HTML5 audio or video — HOW IT WORKS — Shaker hooks into the Web Audio API to read the frequency spectrum of media playing in your tab. It compares low-frequency energy against mid-range energy in real time, so it only reacts when bass actually dominates the mix — not whenever there is sound. A CSS transform on the page body produces the shake; nothing is recorded, uploaded, or stored. — PRIVACY — 100% local. No audio leaves your device. No tracking. No accounts. No analytics. The only data stored is your two settings (on/off + intensity), synced via Chrome's built-in storage if you're signed in. — NOTES — • Reload tabs after installing for the script to attach. • Cross-origin audio streams without proper CORS headers cannot be analyzed by the browser and won't trigger a shake. This is a Web Audio limitation, not an extension bug. • If a site looks weird while shaking, lower the intensity slider or toggle Shaker off — the page returns to normal instantly. Feel the drop.
