SuperVolume - Sound Amplifier and Equalizer — iobyss

SuperVolume turns up the volume on any browser tab — far beyond the system limit — with a clean, professional audio engine.

🔊 VOLUME BOOSTER
Amplify quiet videos, calls and music up to 600% (1000% if you raise the cap). A safety limit lets you restrict the maximum to protect your hearing, and a soft limiter keeps loud peaks from distorting.

🎛 5-BAND STUDIO EQUALIZER
Shape the sound with presets (Music, Clear Speech, Podcast, Night Film) or fine-tune every band yourself, from 60 Hz sub-bass to 14 kHz air.

🔊 SMART VOLUME LEVELING
A gentle compressor tames loud ads and sudden explosions and lifts quiet dialogue — comfortable listening without constant volume fiddling.

🌙 NIGHT MODE & AUTO-GAIN
Night Mode flattens loud scenes, cuts low rumble and boosts speech clarity, so you can watch films late without waking the house. Auto-Gain keeps every video at the same comfortable loudness.

🎧 MONO DOWNMIX
Merge left and right channels — ideal for single-earbud listening or unbalanced audio.

💾 PER-SITE MEMORY
SuperVolume remembers your volume, EQ and modes for each website and restores them automatically on your next visit. Optional auto-boost starts the engine for you.

🎨 12 THEMES & 5 BACKGROUNDS
Eight hand-tuned palettes — Aurora Cyan, Sunset Pink, Neo Mint, Amber, Ultraviolet, Crimson, Lime and Monochrome — plus five background styles: Midnight, OLED Black, Graphite, Nebula and Dusk.

📊 LIVE VISUALIZER
Five styles: Holographic Wave, Retro LED Spectrum, Mirror Spectrum with peak-hold, Bass Bloom and the scrolling Spectrum Rain spectrogram.

Toggle the boost and change volume without opening the popup. All shortcuts can be reassigned in your browser.
