Nagra III Audio Recorder - Working. Circa 1963.

Nagra is a brand of portable audio recorders produced from 1951 in Switzerland. Beginning in 1997 a range of high-end equipment aimed at the audiophile community was introduced, and Nagra expanded the company’s product lines into a new marketplace.

Originally a product of the Kudelski Group, Nagra recorders are now developed, produced and sold by independently-owned company Audio Technology Switzerland S.A., based in Romanel-sur-Lausanne.

The machines were initially designed by Polish inventor Stefan Kudelski, and his company won numerous technical awards for their precision and reliability. Nagra means "[it] will record" in Polish, Kudelski's mother language.

Nagra-brand tape recorders were the de facto standard sound recording systems for motion picture and (non-video) single-camera television production from the 1960s until the 1990s.
