An app that transmits information around a detonate of "digital birdsong" aims to facilitate the way users share images and other files between smartphones.
Chirp plays a two-second long sound that sounds as if it was done by a robotic bird. When listened by other gadgets it triggers a download.
The program was created by Animal Systems, a offshoot business from University College London (UCL).
It is giveaway to use, but companies will be charged a price for extras services.
At the short time users are paltry to sending pictures, website links or 140-character content messages. These show up in a feed identical to Facebook's timeline.
Other applications such as Android Beam, Bump, Datasync and Dropbox enable users to barter element around bluetooth, wi-fi or links to cloud-based storage.
But Chirp has the value that it can rapidly send information to multi-part gadgets at once without them wanting to be possibly interconnected or have a wireless connection.
If recipients are offline their gadgets will recollect the "chirp" and download related content later.
"We are flattering certain this is unique," the firm's arch senior manager Patrick Bergel told the BBC.
"We compromise the complaint of having to span gadgets to pierce data. It's sincerely novel to be able to broadcast information to any person who is in reach - a considerable number of gadgets can share the same information at the same time using sound.
"You can moreover use it as a device changeable mechanism. In the future you will be able tweet yourself a couple to a chart from your laptop."
Mr Bergel says Chirp's unmatched sound allows it to work at low volumes in comparatively loud locations such as pubs, clubs or active streets.
It can moreover work over open residence systems or air wave transmissions - potentially permitting broadcasters a way to send present cinema or links to credentials information; or an advertiser to send coupons or snippets of a strain or promotional video.
Animal Systems subscribes to a "blacklist" service to stop users transmitting well known racy or illegal-content website links. However, it does not outline to reasonable other material.
The focus functions by uploading a user's element to the firm's servers. The information is then identified with a 50-bit residence space: a of trillions of existing identifiers.
This place is then sent to the sender's device. When the user presses a symbol in the app it plays an audio-encoded chronicle of the address.
Data has long been transfered between machines in the form of sound, inclusive recordings on tapes used to bucket programs in to 1980s home computers and early modems dialling in to networks.
Even so, Mr Bergel mentioned he had taken stairs to stop others duplicating his product.
"We have a systems obvious on relocating short codes over the air," he said.
"We have [also] solved a lot of tough problems. There's a lot of technical problems around relocating information and creation it strong against sound and echoes."
Having launched the app the five-man group at the back it will right away focus on gift reward services to marketers and other businesses.
Mr Bergel mentioned these could include:
A pledge that uploaded content would be henceforth kept on the firm's servers.
Access to methodical information vouchsafing firms follow whose gadgets have "listened" to their chirp.
The skill to send video messages that fool around inside of the Chirp app.
Mr Bergel mentioned the best goals was to see manufacturers pre-install Chirp on handsets.
However, he contingency initial remonstrate users that they need the service at a time when wi-fi, 4G information and modernized bluetooth connectivity are apropos increasingly common.
For right away Chirp is usually existing as an iPhone app. An Android chronicle is betrothed "soon".
