Audio Fidelity Records

Audio Fidelity Records, was a record company out of New York City, most active during the 1950s and 1960s. They are best known for having produced the first mass-produced American stereophonic long-playing record in November 1957 (although this was not available to the general public until March of the following year).

Background

Sidney Frey (1920–1968), founder and president of Audio Fidelity, had Westrex, owner of one of the two rival stereo disk-cutting systems, cut a stereo LP disk for release before any of the major record labels, several of which had the Westrex equipment but had not yet produced a stereo disk. Side 1 was The Dukes of Dixieland; Side 2 was railroad sound effects. This demonstration disc was introduced to the public on December 13, 1957 at the Times Auditorium in New York City. 500 copies of this initial demonstration record were pressed. On December 16, 1957, Frey advertised in the trade magazine Billboard that he would send a free copy to anyone in the industry who wrote to him on company letterhead.
