A piece of equipment which detects and filters amplitudes of electromagnetic behavior in realtime into audiable sound, giving the illusion of sound in space. In this way based on the humanoid cognition of sound within an atmosphere, sounds describing compression, expansion, special amplitude behaviors, velocity and direction. Real electromagnetic information is filtered and then modified via a neural network into these meaningful sounds which are highly recognisable, easy to localize in direction, distance and velocity and easy to identify similar characteristics of and thus relationships between different signal types.
In this way while many devices are specially modified to conceal their exact recognisable outputs to make them more difficult to identity, people who are sufficiently experienced eventually learn the “flavor” of space and learn to hear these sounds naturally.
In some cases, sonic detectors are also used in atmosphere to indicate behavioral characteristics of planetoids or nebulae for navigation and feature special features which avoid signal noise from overriding the signal, special filtering based on intent and interest recognition with neural systems and even direct-feeding systems which allow a person's own brain to skip the audio interpretation and move directly into signal decoding – a talent expected of most military dogfighters, specialty sensor operators and signal engineers. As such, it isn't uncommon to have a dedicated team member or second pilot for the purpose of signal decoding.
