Tab Audio Router

Overview

Tab Audio Router

Route different tabs to different outputs

Send each browser tab’s audio to a different device on Mac.
Example: YouTube → TV, Zoom → Headphones.

Why this exists

macOS + browsers don’t let you easily control audio per tab.

This fixes that — right from the right-click menu.

How it works

Right-click menu to choose audio output

  • May ask for microphone access so Chromium can label output devices (enumerateDevices).
  • Right-click the video or audio element.
  • Open Audio outputs → Choose output… and pick a device in the on-page list, or use Use system default.
  • Done — that player now uses the output you chose.

What you can do

  • 🎧 Zoom in headphones, music on speakers
  • 📺 Send a tab to your TV while working on laptop audio
  • 🔀 Run multiple tabs with different outputs

Install (30 seconds)

Limitations (important)

  • Only works on sites using standard <audio>/<video>
  • Some apps (Zoom web, Spotify web) may not route correctly
  • Chromium browsers only (Chrome, Arc, Brave, Edge)
