Per-Tab Volume Control per Harrison Jones

Take full control of your browser's audio. Whether a video is too quiet, poorly mixed, too loud in places, or you want better control across multiple tabs, Per-Tab Volume Control gives you the tools to fix it instantly.

🚀 Key Features
- 🔊 500% Volume Boost: Blast past the system limit. Perfect for quiet YouTube videos, low-volume podcasts, online meetings, and streams that are just too faint.
- 🎛 Smart Audio Compressor: Automatically balances audio levels. It lowers loud explosions and boosts quiet dialogue, so you do not have to constantly reach for the volume knob.
- 🔇 Mute, Mono and L/R Balance: Instantly mute the current tab, force mono audio, or shift sound left and right directly from the main popup.
- ⌨ Keyboard Shortcuts: Adjust volume, reset volume, mute or unmute, and toggle compressor on the active tab without opening the popup.
- 🎯 Cross-Tab Audio Control: Manage volume, mute, and compressor settings for all tabs with active audio from one convenient panel.
- 🌍 Global Audio Defaults: Set Compressor and Mono defaults for newly opened or reloaded pages, and use Global L/R Balance across open tabs and new pages while enabled.
- 🗣 Multilanguage Support: Switch the popup language from Settings: English, Spanish, German, French, Russian, or Simplified Chinese.
- ✅ Per-Tab Isolation: Adjust one tab without affecting the others. Listen to music in the background while watching a tutorial at a different volume.
- 🌐 Broad Compatibility: Works on most websites with HTML5 audio and video, including YouTube, Twitch, Spotify, Netflix, and more.
- 🔒 Privacy First: Runs 100% locally on your machine. No tracking, no data collection, no ads.

💡 How to Use the Audio Compressor
Think of the compressor as an automatic volume assistant. It smooths out the difference between the loudest and quietest parts of a video, making quiet dialogue easier to hear without being blasted by sudden loud sounds.

Turn it On: Toggle the Compressor switch in the popup.

Threshold (Sensitivity):
- Lower sensitivity (for example, -10dB): Compression only kicks in for the loudest peaks, leaving most audio untouched.
- Higher sensitivity (for example, -40dB): Compression reacts to much more of the audio, helping with whispering dialogue or inconsistent podcast levels.
- Default (-18dB): A balanced starting point for most content.

Ratio (Strength):
- Low (2:1): Gentle, subtle leveling with a more natural sound.
- Medium (6:1 - Default): Balanced compression for everyday listening.
- High (12:1): Strong limiting that pulls loud and quiet sounds closer together. Great for late-night watching.
