These programmes reveal the secret work of the Institute of Radiophonic Evolution in South Mimms - drawing on conference calls, voice notes and life-logs, to tell a compelling and strange story of the technological lengths to which the researchers will go to push forward the boundaries of the emerging digital technologies.

Each week a jiffy bag of sound files arrives at the BBC. We listen to the contents to discover what backroom boffins Luke Mourne and Professor Trish Baldock (ably assisted by Shelley – on work experience) have been up to.

In this episode, they develop the Absence App and use it to disrupt a politically controversial radio broadcast.
