Background

The origin of SM57 may be traced to 1937, when Shure engineer

developed the first single-element directional microphone, the Unidyne, which had a

pickup pattern. In 1959, another Shure engineer, Ernie Seeler, advanced the art of microphone design significantly with the Unidyne III capsule which was later used in the SM57. After three years of
