VoluTab: Per-Tab Volume Control & Booster

VoluTab is the ultimate lightweight, privacy-first audio controller and volume booster for Google Chrome. Control sound levels independently on every single tab, boost quiet audio up to 500%, and manage all audible background tabs in one sleek, modern popup. Whether you're struggling to hear a quiet lecture on YouTube, balancing Spotify music while playing a browser game, or muting annoying autoplay ads on news websites, VoluTab gives you studio-grade control over your browser’s audio. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⚡ KEY FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🚀 500% Audio Booster Amplify quiet videos, podcasts, and audio streams up to 5x beyond standard maximum volume with zero latency. 🎛️ Independent Per-Tab Control Adjust volume for specific tabs without changing your global computer or system audio. Changing volume on Tab A never touches Tab B. 📋 Live Background Audible Tabs List Instantly see every tab that is currently playing sound across your entire browser. Adjust their volume sliders or mute them with a single click—no need to switch between tabs. 🛡️ Studio-Grade Limiter (No Distortion) Equipped with an integrated DynamicsCompressor node that automatically acts as a ceiling limiter, preventing harsh audio clipping and speaker crackle at high boost levels. 🔒 Bulletproof CORS & DRM Protection Unlike other boosters that permanently mute or crash when encountering protected streams (Spotify, JOOX, Netflix, Apple Music), VoluTab intelligently falls back to safe native HTML5 audio control so your music never dies. 💾 Per-Domain Volume Memory Optional automatic volume memory remembers your preferred volume level for your favorite domains (e.g., set YouTube to 180% and it stays that way next time). 🔇 One-Click Mute & 100% Reset Quickly mute any tab with the dedicated mute toggle or snap right back to standard 100% volume with the reset button. ⚡ Quick Preset Chips One-click jump to 50%, 100%, 150%, 250%, or 500% boost. ⌨️ Keyboard Accessible Adjust volume directly with your keyboard without touching your mouse: • M — Toggle Mute / Unmute • R — Reset volume to 100% • Left / Down Arrow — Decrease volume by 5% • Right / Up Arrow — Increase volume by 5% ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🛡️ 100% LOCAL PRIVACY GUARANTEE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Zero data collection. • Zero remote server requests or third-party telemetry. • No account or login required. • Runs 100% locally inside your browser sandbox. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔍 PERMISSIONS DISCLOSURE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ VoluTab strictly adheres to Google Chrome Manifest V3 security standards and requests only the minimum necessary permissions: • "tabs": To detect which tabs are currently playing audio (audible: true) and display their titles and favicons in the popup. • "storage": To locally save your per-domain volume preferences and UI settings (stored strictly on your machine). • "scripting" & "<all_urls>": To attach the volume booster to HTML5 audio/video elements across your open tabs. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 💡 USAGE TIPS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1.
