Sonora EQ — Equalizer & Volume Booster

Equalizer, volume booster up to 400% and spectrum analyzer for any browser tab. Simple, private, no ads.

Sonora EQ is an equalizer and volume booster for any browser tab. Video too quiet? Laptop speakers sound flat? Want more bass in your music or a clearer voice in a podcast? Sonora EQ lets you shape the sound of any tab in seconds — no software to install, no sign-up. HOW IT WORKS 1. Open a tab that plays audio: music, video, podcast, stream. 2. Click the Sonora EQ icon and press “Turn on”. 3. Drag the points on the graph or turn the knobs — the sound changes instantly. FEATURES • Volume up to 400% — a handy side slider and one-click mute. • Parametric equalizer with up to 16 bands — drag points with the mouse: left/right for frequency, up/down for gain, mouse wheel for width. • 7 filter types: peak, low and high shelf, low-pass, high-pass, notch, band-pass. • Real-time spectrum analyzer — see how the tab sounds. • Limiter — prevents distortion and clipping when boosting a lot. • Preamp, left/right balance and Mono mode (great with a single earbud). • “Compare” switch — instantly hear the difference with and without the EQ. • Your own presets — save the sound you love and switch to it in one click. • Several tabs at once, with a list of all active tabs. • A separate control window that stays open when you click elsewhere. • Keyboard shortcuts for fine-tuning. • Interface in English, Russian and Ukrainian. • Minimal dark design. PRIVACY Sonora EQ does not collect or send any data. Audio is processed only on your computer and is never recorded. Settings are stored only in your browser. No ads, no accounts, no trackers. PLEASE NOTE Protect your hearing: heavy volume and bass boosts can damage your hearing and speakers. Start with small values. The browser itself does not allow audio capture on its internal pages (settings, extension store).
