Google Tone is most likely not what you think. It has zero to do with music, for one, or for doling out in any way to which we’re used to. Okay, it’s pretty much based on sound, but not sound that we as being can hear. There are no locations, digital handshakes, or encryption keys involved here. Ironically, network security is amusingly naked, on the other hand, blocking out wire tappers is as easy as pie. There are no locations, computerized handshakes, or encryption keys.

Google Tone is a Chrome browser extension that is confined to one simple task: at the press of a single button, it will show the URL (in encoded tons) right now being seen on the broadcaster’s PC to every other PC within the earshot that has the extension installed. Users of this pretty simple extension can talk to people within the same group using microphones and speakers. The aim of this extension is to keep conversation between humans secure and private.

The initial prototype of extension was used as an audio transmission scheme that sounded ghastly, turning the researchers to play it beyond the range of human hearing. Since, laptop microphones and almost all video conferencing systems are optimized for voice feature, it enhanced further by incorporating a DTMF-based audible codec. The synthesis can be used for short distances in most audio environment, at low volumes, as well as with Hangouts.

The team behind the extension is increasingly used it to speedily share documents with team members in meetings with simple copy-paste, to share design files with each other while working on user interface design, and to share important links without conversations being interrupted.

Hit or miss, Google Tone? We’ll let you decide that.
