An “audio-digital system” is a transspheral functional unit consisting of elements of the digital infosphere on the one hand and the entisphere on the other hand, which are connected to each other in a way that enables interaction aimed at the fulfilment of a function, a purpose or a task.

The definition of the term “audio-digital system” was proposed as part of the terminology of the “Digital Era Framework”. In this reference framework, four spheres are distinguished on the basis of the type of information manifestation, on the basis of which a classification of systems can take place: The infosphere, which consists of the analog infosphere and the digital infosphere, the cognisphere and the entisphere.
