Amplifies audio on the current tab using the Web Audio API. Includes a volume slider, bass boost toggle, and a VU meter. **Volume Booster Pro** amplifies audio on any website up to 600% — perfect for quiet videos, music, podcasts, and video calls. **Key Features:** - Boost volume up to 600% on any tab - Beautiful circular volume knob with precise slider control - Quick presets: 100%, 200%, 400%, 600% - Per-site volume memory — your settings are remembered - Real-time VU audio meter — see your audio levels - Bass Boost mode for richer, deeper sound - Hearing protection warning at 400%+ volume - One-click mute button - Shows current tab info (favicon + title) - Dark theme with sleek, modern design - No ads, no tracking, no data collection **How It Works:** Volume Booster Pro uses the Web Audio API to create a gain node that amplifies audio beyond the browser's default 100% limit. This works with any audio or video element on any website — YouTube, Netflix, Spotify Web, Zoom, and more. **Bass Boost:** Enable Bass Boost for enhanced low-frequency response. Uses a professional-grade low-shelf filter at 200Hz for rich, deep bass without distortion. **Hearing Protection:** Your hearing matters. Volume Booster Pro shows a clear warning when you exceed 400% volume. We recommend keeping volume at comfortable levels and taking breaks during extended listening sessions. **Privacy:** Volume Booster Pro stores only your per-site volume preferences locally on your device. No data is sent to any server. No analytics, no tracking, no accounts required. **Free & Open:** Volume Booster Pro is completely free to use with no limitations.
