A new Chrome extension can instantly share URLs among nearby devices, using sound to broadcast the information to microphones.

Google Tone is an experimental feature that could be used to easily share browser pages, search results, videos and other pages among devices in an office, classroom or family setting, according to Google Research.

While it can't pass through walls or travel beyond earshot, the system is designed to make sharing browser URLs as easy as talking to people nearby.

"The initial prototype used an efficient audio transmission scheme that sounded terrible, so we played it beyond the range of human hearing," researcher Alex Kauffmann and software engineer Boris Smus wrote in a post on the Google Research blog.

While microphones on laptops and video conferencing devices are optimized for the human voice, the extension incorporates a codec based on dual-tone multi-frequency signaling (DTMF), a system that has long been used in conventional telephony.

Tone works at low volumes and can be used over Hangouts, but it can be affected by speaker volume and microphone sensitivity.

When the extension is installed, an icon of a megaphone appears at the top right in Chrome. With the device's volume on, sharing a URL is done by clicking the icon.

Users have to be logged into their Google account, and their profile names and photos are displayed alongside the URL in incoming Tone notifications.

Sizing up the NZ security spectrum - Where's the channel sweet spot?

Sizing up the NZ security spectrum - Where's the channel sweet spot?

From new extortion schemes, outside threats and rising cyber attacks, the art of securing the enterprise has seldom been so complex or challenging. With distance no longer a viable defence, Kiwi businesses are fighting to stay ahead of the security curve. In total, 28 per cent of local businesses faced a cyber attack last year, with the number in New Zealand set to rise in 2017. Yet amidst the sensationalism, media headlines and ongoing high profile breaches, confusion floods the channel, as partners seek strategic methods to combat rising sophistication from attackers. In sizing up the security spectrum, this Reseller News roundtable - in association with F5 Networks, Kaspersky Lab, Tech Data, Sophos and SonicWall - assessed where the channel sweet spot is within the New Zealand channel.
