Tab volume booster up to 600% with a 5-band parametric EQ, dynamics compressor anti-clipping, and custom profiles by Nablai.

SoundBoost by Nablai — The next-generation tab volume booster and 5-band studio parametric equalizer for Google Chrome. Boost tab volume up to 600% with zero audio clipping, zero latency, and flawless native HTML5 fullscreen support. Unlike legacy volume boosters that break your browser with simulated screen-share streams, SoundBoost hooks directly into media elements natively. KEY FEATURES: ⚡ Boost Volume Up to 600% Overcome quiet YouTube videos, quiet Twitch streams, quiet movies, or low laptop speaker volume. Easily adjust gain from 0% to 600% or use quick presets (100%, 200%, 300%, 400%, 600%). ⚡ True Native HTML5 Fullscreen (No tabCapture) Traditional boosters use chrome.tabCapture, which breaks native OS fullscreen and traps your video in a laggy WebRTC recording stream. SoundBoost connects directly to the Web Audio pipeline in the DOM, keeping native 4K/8K 60fps fullscreen, GPU acceleration, and Picture-in-Picture 100% intact. ⚡ Studio Dynamics Compressor (Zero Distortion) Say goodbye to painful digital distortion and blown-out speakers. SoundBoost places a hardware-modeled dynamics compressor (-6dB threshold, 8:1 ratio) right before audio output, keeping high-gain sound crisp, punchy, and clear. ⚡ 5-Band Studio Parametric Equalizer Calibrate sound for your specific headphones or speakers: • 60 Hz (Low Shelf): Deep sub-bass and kick rumble • 250 Hz (Peaking): Vocal body, warmth, and low-mid resonance • 1 kHz (Peaking): Speech articulation and podcast dialogue clarity • 4 kHz (Treble Peaking): Treble presence and consonant sharpness • 12 kHz (High Shelf): High-frequency air, space, and shimmer ⚡ Built-In & Custom Audio Profiles Switch instantly between Flat, Bass Boost, Vocal Clarity, and Late Night presets, or create, save, and rename your own custom EQ profiles. ⚡ Domain Memory & Persistence Your preferred volume levels and chosen EQ profiles are saved automatically per website (YouTube, Netflix, Spotify, Twitch, etc.). ⚡ Clean Monochrome Design & Dual-Theme Crafted to modern design standards with dual Dark and Light monochrome modes, adaptive ambient constellation particles, and zero clutter. PRIVACY & PERFORMANCE: • 100% Local processing: zero audio data leaves your device. • 0 trackers, 0 third-party analytics, 0 ads, 0 bloat. • Manifest V3 compliant and battery-friendly.
