Soma Ether is a kind of anti-radio. Instead of being set to a specific radio station, it receives all the interference and radiation that a conventional radio tries to eliminate to produce a clean signal. It captures the radio waves "as they are" from Hertz to Gigahertz because it does not contain the tuned input circuit that filters out all frequencies except the narrow band of a particular transmitter. In this way, Ether can perceive the invisible electromagnetic landscape that humans have created unintentionally and allows you to listen and record electromagnetic live fields.
