App transfers data by 'singing', works in loud areas at low volume

Chirp is a new app which transfers data by singing a series of 'chirps'

A new app has been developed by a new spinout from University College London, Department of Computer Science. Based upon the work of senior researchers, the app transfers data by chirping a series of notes. These chirps are designed to work in loud environments, such as pubs, at low volumes.


Even cooler is that the app can transfer data to multiple devices without being paired to any of them. Each chirp lasts about two seconds and is composed of about 12 distinct notes. When another device hears the sequence of chirps, it decodes it into a shortlink which can then be accessed to download the data.

The chirp can also be saved for later viewing if an active data connection is not available. The ability of being able to transfer to multiple devices without pairing offers a significant advantage over other data transfer apps. More information on the app is available on their site at
