They've made a device that detects the kind of sounds we're not meant to hear...

Scotland, 1933. A group of rogue scholars and enthusiasts, led by Dr Mungo Macrae, have developed new technologies that allow them to detect the sonic activities of paranormal phenomena on the outer edges of the known world... These are the secret radio broadcasts of the Committee of Enigmas, captured and committed to a hidden archive of untold legacies of unexplained events, gathered and exchanged over generations of clandestine research by a trans-global network of expert investigators. Join us as we elicit the sonic discoveries of the weird and eerie - available to those who dare to listen. (Stories and sounds from the secret laboratory of Ruptured World).
