Listen to the Ionosphere breathing

Uncategorized

The Ionosphere, electrically charged layer of Earth’s atmosphere, stretches from 50 to 100km into the sky. Responsible for radio propagation, it is possible to listen to the sound of the winds and radio signals at that altitude, using two metal poles stretching 5 to 6 metres off the ground. Linked by a variety of wires the device, hooked to a recorder and headphones, allows us to listen to the strong winds and radio signald hundreds of kilometres above us. The resulting sound can then be used and distorted with an audio editor such as Audacity or Ableton for “cosmic” relief.

“Ionosphere Orchestra”, the creative composition that CAP students improvised, will make your ears bleed but it offers a view into the possibilities that can be achieved through various ethnographic practices and audio editing.
