1 gen 1920 anni - 1920 – First electrical recordings

Descrizione:

First electrical recordings are made by scientists at the Bell Laboratories in the United States. The first electrical recording issued to the public was of November 11, 1920 funeral services for the Unknown Soldier in Westminster Abbey, London. The microphones used were like those in contemporary telephones. They were inconspicuously set up in the abbey and connected by wires to recording equipment in a vehicle outside. Although electronic amplification was used, the resulting audio was weak and unclear. The novel procedure did, however, allow a recording to be made which would otherwise not have been practical in those circumstances.
