About

🔊 VOLUME BOOSTER PRO — Bass Boost, EQ & 600% Loudness

Lift the bass on quiet music, cut the mids for clearer dialogue, push any tab past Chrome's volume limit — all from one beautiful popup. Per-tab, per-site, no accounts, no tracking.

━━━ WHY VOLUME BOOSTER PRO? ━━━

Most boosters give you one slider and call it a day. Volume Booster Pro is a full mini-mixer: a real 3-band equalizer for every tab, a master slider when you've got several tabs going at once, and per-site memory that remembers your EQ and volume forever. It's the audio panel Chrome forgot to ship.

━━━ FEATURES ━━━

🎶 Real 3-band Equalizer (±12 dB)
A proper Bass / Mid / Treble EQ on every tab — not a fake "bass boost" preset. Crank low-end on under-mixed podcasts, dip muddy mids on bad streams, lift treble for sparkle on music. Each setting is saved per site automatically.

🔥 Bass Boost done right
Powered by Web Audio biquad filters (lowshelf at 200 Hz, peaking at 1 kHz, highshelf at 4 kHz). Real DSP, not a volume curve trick — your speakers actually feel it.

🎚 Boost up to 600%
Push past Chrome's normal limit using the Web Audio API GainNode. Quiet videos, soft podcasts, and badly mastered streams finally hit a usable level.

🎛 Per-tab volume
A dedicated slider for every tab that's playing audio. Mix YouTube at 60% and a podcast at 220% simultaneously without leaving the popup.

🎚 Master slider
When two or more tabs are active, a Master control appears at the top. One slider, one mute button — adjust everything at once.

💾 Per-site memory
Set YouTube to 80% with a flat EQ, Spotify to 200% with +6 dB bass, Netflix to 120% with cut mids — Volume Booster Pro remembers and auto-restores everything every time you visit. No "reset on reload."

🎯 Smart presets
Built-in presets: Night (40%), Normal (100%), Boost (200%), Party (400%). Create your own custom presets with one click.

🔇 One-click mute / unmute
Circle-icon mute button in every tab card and the master row. Click once to silence, click again to restore — with a smooth fade so there's no audible pop.

⚡ Keyboard shortcuts
• Alt + Shift + ↑ — volume +20%
• Alt + Shift + ↓ — volume −20%
• Alt + Shift + M — toggle mute on the active tab
(Fully rebindable at chrome://extensions/shortcuts)

🖱 Right-click controls
Context menu on any page: mute, unmute, set volume to 100% / 200% / 400% — no popup required.

🚀 Quick access bar
One-click jump to YouTube, Spotify, and Netflix. The button lights up when you already have a tab open there.

🎨 7 polished themes
Ocean (default), Midnight, Emerald, Sunset, Rose, Light Clean, Light Warm — automatically picks dark or light based on your system, switchable any time from the header.

━━━ PRIVACY ━━━

• No accounts, no sign-in, ever
• No analytics, no telemetry, no remote servers
• All settings live in chrome.storage.local on your machine
• Source available on request

━━━ TECHNICAL ━━━

• Manifest V3
• TypeScript, zero runtime dependencies
• Lightweight popup with no framework runtime
• Works on every site that uses standard <audio> / <video> elements

━━━ KNOWN LIMITS ━━━

• DRM-protected streams (Widevine, etc.) cannot be amplified — this is a browser-level restriction, not an extension bug
• Boosting past ~300% can introduce clipping on already-loud content; use the EQ to compensate
