The needle tins arranhava it and later, passed for the same ridges, it reproduced the sound. Proper Edison inaugurated its phonograph or “machine of speaking” reciting verses of the infantile song Mary had little lamb.

Many other attempts to arrive itself at a recorder had been made. Nothing very practical up to 1935, year where German company I.G. Farben produced a coil ribbon magnetic. Little time later, also the German AEG Telefunken created the “Magnetofone”, that it could record and reproduce the sound. During World War II, the senders of radio of Germany had used the new machine to record the speeches of Adolf Hitler and later placing them in air.
