Overview

Audio Fidelity Records was an American record company founded in 1954 by Sidney Frey and based in New York City. Although its catalog covered popular music, jazz, classical repertoire, spoken or demonstration material, and sound-effects recordings, the label is chiefly remembered for helping move stereophonic long-playing records from specialist demonstrations into the commercial record market. Its activity was especially significant in the late 1950s and 1960s, when stereo reproduction was shifting from an expensive audiophile technology toward a consumer format. Frey worked with Westrex, one of the competing developers of stereo disc-cutting systems, to prepare a stereophonic demonstration record before the major American record companies had released comparable commercial stereo LPs. The disc combined a performance by the Dukes of Dixieland on one side with railroad sound effects on the other. Audio Fidelity presented the demonstration at New York's Times Auditorium in December 1957 and pressed 500 copies for the initial event. Frey subsequently promoted the record to the trade, offering copies to people in the recording industry. His advocacy helped make him known in the period as “Mr. Stereo.” The label's first four stereo LPs for general public release appeared in March 1958. They included Johnny Puleo and his Harmonica Gang, a railroad sound-effects album, Lionel Hampton and his Orchestra, and the Dukes of Dixieland. Audio Fidelity followed those releases with additional stereo titles and became an important early source of commercially available stereophonic programming. The broader market was aided by the sharp reduction in the price of stereo magnetic cartridges in 1958, which made stereo playback more accessible to household consumers. Audio Fidelity also expanded beyond its early demonstration and popular-music catalog. In the summer of 1958 it recorded a group of classical LPs in London with the specially assembled Virtuoso Symphony of London. The sessions involved British orchestral musicians and conductors including Alfred Wallenstein, Arthur Winograd, and Emanuel Vardi, and produced recordings ranging from major symphonic works to overtures, marches, and waltzes. A British branch, A-F England, Ltd., was established in 1959, reflecting the label's interest in the international record business. Frey sold the company in 1965 to Herman Gimbel, who was also known as Herman Levy. Audio Fidelity, Inc. changed its corporate name to Audiofidelity Enterprises, Inc. in May 1971, while releases continued to be associated with the Audio Fidelity label. The last known releases under the label date from approximately 1984. In 1997, the business was purchased out of bankruptcy by Colliers Media Company. The Audio Fidelity label was later acquired by 43 North Broadway, LLC. The historical operating company is therefore treated as defunct, while the trademark and catalog identity have continued as acquired assets. The label remains of interest to collectors, recording historians, and researchers studying the transition to stereo. A collection compiled by collector Don W. Reichle and housed at Syracuse University Library documents 1,404 catalog numbers, 1,176 identified artists, 5,857 track titles, and 640 album-jacket images. This archival record illustrates the breadth of Audio Fidelity's output beyond the small number of pioneering stereo releases for which it is best known.

History

Audio Fidelity emerged in 1954 during a period when recording technology was becoming increasingly important to the consumer music business. Founded in New York by Sidney Frey, the company operated as a record label and recording enterprise at a time when high-fidelity equipment, magnetic tape, and experimental multichannel reproduction were attracting attention among enthusiasts. Its most important historical contribution came from its decision to commercialize stereophonic disc recordings before stereo LPs had been adopted by the major record companies. Frey collaborated with Westrex, which controlled one of the two competing stereo disc-cutting systems, to produce a demonstration record intended to make the effect of stereophonic sound immediately understandable. The disc placed a Dukes of Dixieland performance on one side and railroad sound effects on the other, using contrasting material to demonstrate separation and spatial realism. Audio Fidelity presented the record publicly at the Times Auditorium in New York on December 13, 1957, with an initial pressing of 500 copies. Frey promoted the demonstration through the recording trade, including an offer advertised in Billboard to send a copy to industry personnel who wrote on company letterhead. His public advocacy earned him the nickname “Mr. Stereo.” The company converted this publicity into a commercial release program. In March 1958, Audio Fidelity issued four stereo LPs to the general public: Johnny Puleo and his Harmonica Gang Volume 1, Railroad—Sounds of a Vanishing Era, Lionel Hampton and his Orchestra, and Marching Along with the Dukes of Dixieland Volume 3. Four more stereo LPs were available by the end of that month. The releases appeared as playback technology was becoming more affordable. In June 1958, the price of a stereo magnetic cartridge fell sharply from the level previously associated with specialist equipment, helping stereo records reach a broader home-audio audience. Audio Fidelity's catalog was not limited to stereo showcases. The company issued popular and jazz recordings, sound effects, and other material suited to demonstrations of recording fidelity. It also pursued classical repertoire. During the summer of 1958, the label recorded 13 classical LPs at Walthamstow Town Hall in London with the specially formed Virtuoso Symphony of London. The participating musicians included prominent London instrumentalists such as Anthony Pini, Frederick Riddle, Reginald Kell, and Marie Goossens. Alfred Wallenstein conducted much of the symphonic repertoire, including works by Brahms, Tchaikovsky, and Berlioz; Arthur Winograd directed lighter orchestral selections; and Emanuel Vardi conducted a Strauss waltz album. A-F England, Ltd. was established in 1959, giving the enterprise a formal British presence. Frey sold Audio Fidelity in 1965 to Herman Gimbel, born Herman Levy. The company continued operating under the Audio Fidelity identity, although its corporate structure later changed. In May 1971, Audio Fidelity Records, Inc. adopted the name Audiofidelity Enterprises, Inc. The label remained active for many years, but the last known releases carrying the Audio Fidelity name date from approximately 1984. The original operating business subsequently encountered financial difficulties and was purchased out of bankruptcy by Colliers Media Company in 1997. The label's later history is best understood as the history of a catalog and trademark rather than that of a continuously operating independent record company. The Audio Fidelity label was eventually acquired by 43 North Broadway, LLC. Its historical importance is preserved in discographies, surviving pressings, and institutional collections. Don W. Reichle's extensive Audio Fidelity collection and database, now held at Syracuse University Library, records 1,404 catalog numbers, 1,176 artists, 5,857 track titles, and 640 album-jacket images. These holdings demonstrate that the label's contribution extended well beyond its landmark stereo demonstrations and included a substantial body of popular, jazz, classical, and effects recordings.
