Volume Control Persistent

# Volume Control: Persistent Per-Site Sound (Pro)

**Tired of getting blasted by loud auto-play videos or notification sounds every time you open a new tab?**

Most volume extensions use a technical shortcut to boost sound that breaks your browser's Fullscreen mode, causes audio lag, and drains your CPU.

**Volume Control: Persistent Per-Site Sound** is different. It uses native automation to control audio and video tags directly, and now—starting with version 1.5—it also intelligently masters the **Web Audio API**. The result? Smooth, crystal-clear sound that stays exactly where you set it—forever—without breaking a single feature of your browser.

### 🚀 WHY USERS LOVE IT
* **Set-and-Forget:** Set YouTube to 40%, your news site to 10%, and your music player to 80%. We remember your levels for every domain.
* **Web Audio API Support (New in 1.5):** Now controls volume for advanced web apps, games, and browser-based synthesizers that don't use standard tags.
* **True Fullscreen Support:** Unlike competitors, our native approach never breaks the "Fullscreen" button on YouTube, Netflix, or Twitch.
* **Zero CPU Impact:** We don't "process" the audio stream; we simply automate the native volume levels. It’s the lightest volume manager on the market.
* **SPA Ready:** Works perfectly on modern sites (like WhatsApp, Slack, or Facebook) that load content dynamically.
