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 new markets.
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.
