High fidelity

High fidelity—or hi-fi or hifi—reproduction is a term used by home stereo listeners and home audio enthusiasts to refer to high-quality reproduction of sound to distinguish it from the poorer quality sound produced by inexpensive audio equipment, or the inferior quality of sound reproduction that can be heard in recordings made until the late 1940s. Ideally, high-fidelity equipment has minimal amounts of noise and distortion and an accurate frequency response.

History

Bell Laboratories began experimenting with wider-range of 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.
