TabTuner

Tab volume booster and audio equalizer — adjust any tab from 0% to 600% using shortcuts or the context menu.

Take control of each tab’s audio with volume adjustment from 0% to 600%, customizable audio effects, keyboard shortcuts, and quick context-menu controls. TabTuner captures the audio output of a tab only after a direct user action and processes it locally using the Web Audio API. This provides reliable volume and audio-effect control without modifying the website’s own media players or scripts. ✨ FEATURES 🔊 0–600% volume control — amplify quiet audio or reduce anything that is too loud 🎚️ Audio effects — adjust bass, mids, treble, stereo balance, and mono playback ⏸️ Effect bypass — temporarily pause audio effects without losing your settings 🖱️ Context menu — apply customizable volume steps directly from the right-click menu ⌨️ Customizable keyboard shortcuts — control volume, effects, presets, and manage connected tabs 🌐 Site presets — save and restore volume and audio settings for individual websites 🔗 Connected-tab overview — view, open, mute, adjust, or disconnect tabs currently controlled by TabTuner 🌗 Light and dark themes — follow the system automatically or choose a theme manually 🎨 Custom accent colors — choose between gold, red, blue, violet, and silver ⚡ Lightweight and focused — no advertisements, accounts, analytics, or tracking 🔐 PERMISSION REQUIREMENTS These permissions are required for its core features: • Access the active tab — allows TabTuner to process audio only after you interact with the extension, its context menu, or a keyboard shortcut. • Capture tab audio — enables local volume adjustment and audio effects such as bass, treble, mono, and balance. Audio is never recorded or transmitted. • Storage — saves volume settings, site presets, and interface preferences locally in Chrome. • Scripting — displays a brief visual indicator in the active tab after using a keyboard shortcut. • Context menus — provides the optional right-click volume controls. • Offscreen processing — runs the local Web Audio processing that Chrome service workers cannot perform directly. TabTuner does not request unrestricted access to every website. All audio processing and stored settings remain inside your browser. 🛡️ PRIVACY TabTuner does not collect or transmit personal data, browsing activity, audio, presets, or settings to the developer or third parties. The extension contains no advertising, analytics, tracking services, user accounts, or remotely executed code. The developer has no access to information processed by TabTuner.
