SonicShield: Volume Normalizer & Audio Manager

SonicShield is the ultimate audio control assistant for your browser. It acts as a premium, smart volume manager that automatically remembers your sound preferences per website, boosts quiet audio up to 600% safely, and protects your hearing from sudden loud spikes. Whether you are listening to quiet podcasts, watching loud action movies late at night, or balancing background tabs, SonicShield gives you complete control over your browser's audio engine. ★ KEY FEATURES ★ ▶ 600% SAFE SMART BOOST Quiet YouTube video or movie stream? Boost your tab volume up to 600%. SonicShield automatically engages a soft-knee dynamics compressor when going above 100%, protecting your speakers and headphones from harsh digital clipping or crackling. ▶ CENTRAL BACKGROUND AUDIO MIXER No more searching through tabs to find where that loud sound is coming from. Open the popup to see a list of all audible tabs and mix their volume levels individually, right from a single centralized panel. ▶ 3-BAND PARAMETRIC EQUALIZER & PRESETS Fine-tune your audio with visual Bass, Mid, and Treble sliders. Instantly toggle between five custom profiles: • Flat: Clean, unaltered audio path. • Bass Boost: Powerful sub-bass for music. • Vocal Clarity: Speech enhancement for podcasts. • Dance (Smiley Curve): Enhanced lows and highs. • Night Mode: Compresses loud spikes, cuts sub-bass, and boosts dialogue so you can watch movies at night without waking anyone. ▶ STEREO BALANCE CONTROL (L/R) Easily slide the audio balance panning between your Left and Right speaker channels. Great for users with single-sided headphones or uneven listening environments. ▶ PERSISTENT WEBSITE PROFILES Configure it once and forget it. SonicShield automatically saves and applies your volume levels, equalizer presets, and balance settings per domain name. ▶ CONVENIENT KEYBOARD HOTKEYS Control your sound quickly without opening the extension: • Ctrl + Shift + X: Mute / Unmute the active tab. • Ctrl + Shift + Up Arrow: Increase active volume by 10%. • Ctrl + Shift + Down Arrow: Decrease active volume by 10%. ★ PRIVACY FIRST ★ SonicShield operates entirely in your browser. We do not track, collect, or upload your browsing history, site configurations, or user data. Safe, lightweight, and ad-free.
