The Signal app is an internet radio sweeping app made for ITC
The Signal app is an internet radio sweeping app made for Instrumental TransCommunication (ITC). The idea is modeled after a traditional ghost box that sweeps through AM/FM radio stations and picks up random bits of audio that spirits can use to form speech. Unlike terrestrial radio bands that are filled with a lot of static and harsh sounds this app uses internet radio stations that are static free. This provides a cleaner sounding sweep that has only the speech sounds needed for spirits to communicate.
