Tab Audio Selector

Control audio output device and volume for each tab.

# Control audio output device and volume for each tab independently. "I want to hear the web meeting through my headset, but play background music through my speakers." "This specific video site is too loud, I want to lower the volume just for this tab." Tab Audio Selector is a Chrome extension that solves these problems. You can customize the audio environment for each open tab individually without changing the system-wide sound settings. ## ✨ Key Features & Benefits 1. Switch Output Device Per Tab Route the audio of a specific tab to any connected speaker, headphone, or earphone. * Use Case: Keep your online meeting (Google Meet, Zoom, etc.) on your headset to avoid missing anything, while enjoying YouTube BGM through your high-quality external speakers. 2. Per-Tab Volume Control Even if a webpage doesn't have a volume slider, you can fine-tune the volume from 0% to 500% using this extension (values above 100% boost the audio). * Use Case: Pre-lower the volume for sites that are unexpectedly loud, or boost the volume for quiet videos. You can also mute a tab with a single click, or reset to 100% instantly. 3. Auto-Save Settings The extension automatically remembers the device and volume settings for each site (domain). * Use Case: Settings like "YouTube on Speakers at 50% volume" will be automatically applied the next time you visit the site. No need to readjust every time. * Note: After a browser restart, a `!` badge on the extension icon prompts you to open the popup and restore saved routing. 4. Privacy-First Design All audio processing is done locally within your browser (using Offscreen Documents). No audio data is ever sent to external servers. Microphone permission, required to display device names, is only used temporarily when explicitly granted by the user. ## 🚀 How to Use 1. Open the tab where you want to change the audio output. 2. Click the extension icon in the toolbar. 3. Select your desired device from the Output Device dropdown. 4. Adjust the volume using the Volume slider (up to 500%). Use the **100%** button to reset to the default level when needed. ## 📝 Changelog v1.0.1 * Change the default language to English. v1.0.0 * First stable release * Volume boost up to 500% (values above 100% are shown as boost) * Added a limiter to reduce peak distortion at high boost levels * Added a one-click **100%** reset button v0.0.1 * Initial release * Per-tab audio output device selection * Per-tab volume control and mute * Save and restore settings per domain * Japanese and English support
