Volume Booster 600% & Audio Equalizer gives you full control over your browser sound. Boost quiet videos up to 600%, improve sound quality with an easy equalizer, and control every open tab independently. No more straining to hear quiet videos or scrambling to find which tab is blasting audio. FEATURES - Boost Volume up to 600%: Go far beyond your normal maximum volume for quiet videos, movies, and streams. - Clean Sound, No Distortion: Built-in sound limiter keeps audio crisp and clear without crackling or buzzing at high volume. - Audio Equalizer: Easily tweak your bass, mids, and treble to get the exact sound you want. - Instant Sound Presets: One-click buttons for Bass Boost, Vocal Clarity (for speech & dialogue), Movie Mode, and Flat. - Per-Tab Volume: Each tab has its own volume level, completely separate from the rest. - Quick Presets: One-click jumps to Mute, 100%, 200%, 400%, and 600%. - Mute Toggle: Mute any tab instantly and restore your previous level on unmute. - All Tabs Mixer: See every tab playing audio and adjust volume sliders without having to switch tabs. - Reset All: Restore every open tab back to normal 100% volume in one click. - Light and Dark Theme: Clean minimal design that saves your preference.

No tracking, no accounts, and zero data collected.
