FEATURES

🔊 Volume Boost up to 1000%
Go way beyond the browser's 100% limit. Perfect for quiet videos, podcasts, and streams.

🎛️ 6-Band Equalizer
Fine-tune bass, mids, and treble with 6 frequency bands (60Hz–10kHz). Includes presets: Flat, Bass, Vocal, Treble, and V-Shape.

🔇 Quick Mute
One-click mute with visual feedback on the icon badge and favicon.

⚖️ Left/Right Balance
Pan audio between left and right channels. Great for fixing poorly mixed content or single-earphone use.

🌙 Night Mode
Compresses dynamic range so quiet parts are audible and loud parts won't blow your ears out. Perfect for late-night watching.

🎚️ Normalize
Reduces loud spikes with dynamic compression. Prevents distortion at high boost levels.

⚖️ Auto Balance
Automatically corrects left/right imbalance in poorly mixed audio. Detects persistent stereo offset and compensates in real time.

📡 Mono Mode
Merges stereo into mono — useful when one channel is missing or you're using a single earbud.

🔉 Cut Rumble (High-pass)
Removes low-frequency hum and noise below 80Hz. Cleans up AC hum, mic rumble, and fan noise.

🔈 Low-pass Filter
Cuts harsh high-frequency hiss above 12kHz. Smooths out overly bright or sibilant audio.

💾 Profiles
Save your favorite volume + EQ combos as named presets. Click to load, double-click to rename. Settings auto-save to the active profile. Import and export profiles as JSON for backup or sharing.

🏷️ Per-Tab Memory
Each tab remembers its own volume, EQ, and toggle settings independently. Switch tabs and your settings are right where you left them.

⌨️ Keyboard Shortcuts
• Alt+Shift+↑ — Volume up 10%
• Alt+Shift+↓ — Volume down 10%
• Alt+Shift+M — Toggle mute

🔖 Badge & Favicon Indicator
The extension badge shows current volume level. The page favicon gets a colored dot: green (normal), yellow (loud), red (extreme/muted).
