Volume Booster: Sound Booster & Equalizer

About

🔊 Volume Booster is a simple, reliable sound booster for Chrome that makes any browser tab louder — up to 600% of its normal volume. When a video was recorded too quietly, an online meeting is hard to hear, or your laptop speakers just aren’t loud enough, this volume booster gives you the extra headroom you need in a single click.

⚙️ It’s built around Chrome’s own audio engine, so the boost is applied to the tab’s sound in real time — smooth and stable, with no re-encoding and no lag.

✨ WHAT YOU CAN DO
🚀 Boost volume from 0% to 600% with a precise slider and quick presets (100 / 200 / 400 / 600%).
🎚️ Shape your sound with a 3-band equalizer — bass, mid and treble.
🎵 Use ready-made Music, Movie and Speech presets for the perfect mix.
🔈 Add deeper low-end with the bass boost, or make dialogue and podcasts easier to follow with the Speech preset.
↔️ Adjust left / right balance and blend stereo toward mono.
🛡️ Switch on Anti-distortion to keep loud audio clean at high boost levels.
⌨️ Control the volume from your keyboard with customizable shortcuts.
🌙 Choose a light or dark theme — your choice is remembered.

💜 WHY YOU’LL LIKE IT
⚡ Fast, completely free, and shows no ads.
👀 Designed to be understood at a glance: one big volume dial, clear presets, simple sliders.
🌐 Works on any tab that plays audio — video sites, music, online courses, calls and more.

🔒 HOW IT WORKS — AND YOUR PRIVACY
The extension captures the audio of the tab you are on and plays it back through an amplifier and equalizer running locally in your browser. It does not record, store or send your audio anywhere. There is no account, no tracking and no data collection.

ℹ️ GOOD TO KNOW
Chrome shows a small “this tab is being captured” indicator whenever an extension adjusts a tab’s sound. That is a built-in browser safety feature and cannot be removed — it simply reminds you that audio is being processed. Set the volume back to 100% (or press Reset) and the tab returns to its normal sound.
