High fidelity—or hi-fi—reproduction is a term used by home stereo listeners and home audio enthusiasts (audiophiles) to refer to high-quality reproduction of sound to distinguish it from the poorer quality sound produced by inexpensive audio equipment. Ideally, high-fidelity equipment has minimal amounts of noise and distortion and an accurate frequency response.
One effort to standardize the term was the 1966 German Deutsches Institut für Normung (DIN) standard DIN 45500. DIN 45500 approval was intended to provide audio equipment buyers with reassurance that their equipment was capable of good quality reproduction. In theory, only stereo equipment that met the standard could bear the words 'Hi-Fi'. This standard was well intentioned but only mildly successful; in practice, the term was widely misapplied to audio products that did not remotely approach the DIN basis specifications.
Bell Laboratories began experimenting with wider range recording techniques in the early 1930s. Performances by Leopold Stokowski and the Philadelphia Orchestra were recorded in 1931 and 1932 using telephone lines between the Academy of Music in Philadelphia and the labs in New Jersey. Some multi-track recordings were made on optical sound film, which led to new advances used primarily by MGM (as early as 1937) and Twentieth Century Fox (as early as 1941). RCA Victor began recording performances by several orchestras on optical sound around 1941, resulting in higher fidelity masters for 78-rpm discs.
