TabTuner

Control the volume of each browser tab individually. A professional audio mixer for your browser.

Take full control of your browser's audio. Control volumes, focus on what matters with Smart Focus Mode, lock background audio, and enjoy a beautiful, modern interface. Have you ever had multiple tabs playing audio at the same time, making it impossible to focus? Or wanted to turn down a loud background video without muting it entirely? TabTuner is the ultimate browser volume mixer that lets you control the volume of every open tab individually. With a premium HSL dynamic color design, accessible light/dark themes, and our intelligent Focus Mode, managing your browser’s sound has never been easier or more elegant. Key Features: 1. Per-Tab Volume Control Adjust the volume of any tab containing HTML5 video or audio elements from 0% to 100%. No more blasting sound from unexpected autoplay videos. 2. Smart Focus Mode (Auto-Ducking) Prioritize the tab you are currently viewing! When you enable Focus Mode, TabTuner automatically lowers the volume of all background tabs by a percentage of your choice (e.g., reduce background audio to 20% or 50%) whenever your active tab starts playing sound. Once you pause the active tab or switch away, the background tabs instantly and smoothly return to their original volume. 3. Persistent Pop-out Window Tired of the volume popup closing every time you click elsewhere? Click the Pop-out button to open the mixer in a dedicated, floating window that stays open as long as you need it to. 4. Reactive Equalizer A clean, visual equalizer animates next to each tab in the mixer—but only when that tab is actually emitting sound! Paused or silent tabs display a flat, static indicator, allowing you to instantly identify where the audio is coming from. 5. Lock Tab Volume Protect specific tabs from global changes. Lock the volume of your favorite music playlist tab so that the Master Volume slider or Focus Mode won't affect it. 6. Premium Dynamic UI & Accessibility (WCAG AA) Enjoy a modern UI that transitions smoothly from neutral gray (muted/near-zero) to vibrant emerald green, and all the way to deep indigo at 100% volume. Auto-Contrast: Dynamic HSL color calculations automatically adjust contrast depending on whether you are using Dark Mode or Light Mode, ensuring the UI remains perfectly readable under any conditions. Smooth Animations: Hover states, micro-transitions, and key-press effects make the mixer feel incredibly fast and responsive. 7. Global Keyboard Shortcuts Control your volume instantly without even opening the popup! Volume Up: Ctrl + Shift + Up (customizable) Volume Down: Ctrl + Shift + Down (customizable) How to Use: Click the TabTuner icon in your toolbar to open the mixer. Drag individual sliders to adjust the volume of specific tabs. Click the Lock icon to protect a tab's volume. Toggle Focus Mode and set your preferred background ducking percentage using the slider. Use the Pop-out (↗) button in the top header to keep the mixer open in a persistent floating window. Click the Mute All button in the footer for an instant panic mute. Why Choose TabTuner?
