In 1951, Stefan Kudelski, a gifted 22-year-old engineer, developed an extremely high quality, miniature, self-contained audio recorder which he named simply the “Nagra I”. Nagra is a Polish word meaning “will record”. The interest in his invention was immediate. The Nagra II and III followed in the mid to late ‘50s revolutionizing the world of radio broadcasting, cinema and music.

In recognition of his contribution to culture and science, the Nagra Company received numerous awards including Oscars® in 1978 and 1991. Today Nagra enjoys universal fame and the word “Nagra” describes either an authentic Nagra recorder or is a generic term for a sound recorder.

Audio Technology Switzerland was created in 2012 as a spin-off of the Audio division from the Audio division from the Kudeski group. The members of the Kudelski family are the main shareholders of this new entity. Audio Technology Switzerland SA is present in three principal sectors: high-end Hi-Fi equipment, professional audio recorders and devices destined for security and law enforcement.
