Google Tone: share your links with other using sound

You want to share a link to a website with someone? You can copy and paste it in an email or a chat window. Or, you can use the new extension Google Chrome Tone reserved for the web browser to share the link with any PC in "earshot" .

Indeed, Google Tone share links using the sound.

Here is how it works when Google Tone is active, it uses the microphone and speakers on your computer. You want to share a link? The extension accessible from the browser converts the web address in a sound that can be transmitted over your speakers. When a PC nearby (with Google Tone extension installed) hears that sound, it can open the site.

A sound, Internet and nothing more!

This is not the first time that Google uses a means for transmitting audio data. When the company added support for guest mode to its famous Chromecast last year, the company launched an interesting way for people to pair their smartphones with Chromecast without entering the Wi-Fi password. Chromecast uses your TV speakers to emit a high-pitched sound which sends it to a smartphone Chromecast to start the application.

However, when you use this feature, it is likely that you will not hear the shrill sound, unless you are a superman. However, Google Tone emits a series of loud beeps. This is not the most discreet way to share a website. The extension encodes the markers in a series of beeps - a process called "dual-tone multi-frequency signaling" - the nearby computers with installed Tone can understand.

Google says that Google Tone may not work in noisy environments or places with poor Internet connections. And, the extension will not work if the computers are too far apart. Note that Google will also temporarily store the URL you share on its servers, so if you are not willing to share more data with the Mountain View giant, you may want to only share the old ties way: by writing on a piece of paper or send Su Snapchat or something else.

Google said that Google Chrome Tone is an experimental extension, and that the first version was "built in an afternoon for fun", so she quickly worked on. Nevertheless, this is an interesting application of audio technology and not necessarily useless.
