Broadcast any URL to computers within earshot.
Google Tone turns on your computer's microphone (while the extension is on) and uses your computer's speakers to exchange URLs with nearby computers connected to the Internet. You can use Google Tone to send the URL for any web page, including news stories, pictures, documents, blog posts, products, YouTube videos, recipes—even search results. Any computer within earshot (including over a phone or Hangout) that also has the Google Tone extension installed and turned ON can receive a Google Tone notification.
You need to be logged into your Google account to use Google Tone, and your Google profile name and picture will be displayed with the URL in a Google Tone notification.
To receive a URL with Google Tone, Chrome needs to keep your microphone on. Google Tone may not work in loud spaces, over a distance, with a poor Internet connection, or on computers without a microphone or with a microphone incapable of detecting sound broadcast by Google Tone.
