Send one browser tab’s sound into any call

What “Also share tab audio” does, and where it stops

When you present a Chrome tab in Google Meet, Chrome offers “Also share tab audio”, and it’s on by default: the meeting hears that tab while you present it. Google’s help says that to share audio from a presentation, you present a tab with it on. Teams on the web has the same switch when you share a tab. It works well for a one-off clip, within limits.

• It’s a presentation. Everyone sees the tab, and only one person can present at a time.
• It lives in the browser. It’s there only when the call runs in a tab, such as Meet and Teams on the web. The Zoom and Teams desktop apps have their own switches, which send an app’s sound or the whole Mac’s.
• Not in Safari or Firefox. They don’t offer tab audio when you present. Pick a window or your screen there, and Meet tells you “To share audio, share a tab instead”.
• It sits beside your voice, not in it. The sound goes with the presentation, so you can’t set it under your voice.

Meet’s other option, “Also share system audio”, sends your Mac’s sound with a window or your whole screen. It needs Chrome 142 or newer on macOS 14.2 or newer, it’s off by default, and it’s still a presentation. More in play music on Google Meet.

Patch for Chrome, step by step

Patch for Chrome is a free browser extension for Google Chrome, Microsoft Edge and Arc on a Mac. It sends one tab’s sound into Patch, which we make. Patch mixes it with your microphone into a virtual mic called Patch Mix. Patch needs a Mac with Apple silicon and macOS 26 or later, with its audio component installed or updated (Settings › Audio component).

1. Add a Chrome tab in Patch. In Patch, open the list of sources you can add and choose Add a Chrome tab.
2. Add Patch for Chrome. Add Patch for Chrome from the Chrome Web Store. Chrome asks once about your microphone; that only lets Patch for Chrome find the Patch speaker. It never listens.
3. Pin it. Click the puzzle piece in the browser toolbar, then the pin next to Patch for Chrome.
4. Send the tab. On the tab you want callers to hear, click Patch in the toolbar, then Send this tab.
5. Choose Patch Mix in your call app. In Zoom, Teams, Meet or any other call app, choose Patch Mix as the microphone and your headphones as the speaker.
6. Go live. Click Go live in Patch. From then on, your call hears the tab mixed with your voice.

Click Stop when you’re done, or click Patch on another tab to send that one instead. Get Patch for Chrome.

Works in every call app, desktop apps included

The tab arrives in your call as part of your microphone, so any app that lets you choose a microphone hears it: Zoom, Microsoft Teams, Google Meet, Webex, Discord, Slack huddles and others. The desktop apps work too, which browser tab audio can’t reach. There’s no screen share to start and no share-sound switch to remember.

Each app’s microphone and noise settings are in its own guide:

• Zoom
• Microsoft Teams
• Google Meet
• Webex
• Discord
• Slack huddles

You hear what your callers hear

The tab you send goes quiet in the browser, and you hear it through Patch instead, so what’s in your headphones is exactly what your callers hear. In Patch, the tab shows as a Chrome tab card you can rename, with its own fader and Hear locally switch, so you can sit a video under your voice. A limiter on the mix stops a loud clip from clipping.

Your meeting tab stays out

If your call runs in the browser, such as Google Meet, Teams on the web or Zoom on the web, Patch for Chrome refuses to send that tab, so callers never hear an echo of themselves. That also means the music can play in another tab of the same browser as the call.

Patch for Chrome sends one tab at a time, only the tab you choose, and only after you click. Nothing else from your browser or your Mac goes with it, so notification sounds stay out. If the tab reloads or moves to another site, Patch stops sending it.

Nothing leaves your Mac

Patch for Chrome collects no data and makes no network connections. The tab’s sound goes from your browser to Patch on your Mac, and your call app is the only thing that sends it on, the same way it sends your voice. The microphone prompt is only how it finds the Patch speaker; it never listens. Patch itself is covered on its privacy page.
