Ring-and-spring microphones, such as this Western Electric microphone, were common during the electrical age of sound recording c. 1925–45.. The second wave of sound recording history was ushered in by the introduction of Western Electric's integrated system of electrical microphones, electronic signal amplifiers and electromechanical recorders, which was adopted by major US record labels in ...
Between the invention of the phonograph in 1877 and the first commercial digital recordings in the early 1970s, arguably the most important milestone in the history of sound recording was the introduction of what was then called electrical recording, in which a microphone was used to convert the sound into an electrical signal that was ...
Since the early 1920s, various people have developed this method. The same optoelectronic method also allows for the first time the post-processing of recorded music to sound recordings of it. The director Carl Froelich (1875–1953) turns "The Night Belongs to Us", the first German sound film.
It was developed by two Western Electric researchers, Joseph Maxfield and H. Harrison. Early electrical recordings sounded harsh when played on the acoustic phonographs of the day, which had been designed by trial and error, had highly "colored" frequency response, and emphasized higher frequencies.
Recording was done using a cutting lathe and acetate discs. Programs were normally recorded at 33 1 ⁄ 3 rpm on 16-inch discs, the standard format used for such "electrical transcriptions" from the early 1930s through the 1950s. Sometimes, the groove was cut starting at the inside of the disc and running to the outside.
Thomas A. Edison invented the phonograph, the first device for recording and playing back sound, in 1877.After patenting the invention and benefiting from the publicity and acclaim it received, Edison and his laboratory turned their attention to the commercial development of electric lighting, playing no further role in the development of the phonograph for nearly a decade.
Orlando R. Marsh (August 6, 1881 – September 7, 1938) [1] was an electrical engineer raised in Wilmette, Illinois. [2] In early 1920s Chicago, Illinois he pioneered electrical recording of phonograph discs with microphones when acoustic recording with horns was commonplace.
The American Epic Sessions is a documentary film in which an engineer restores the long-lost first electrical sound recording system on which the 1920s field recording sessions were made, and twenty contemporary artists pay tribute to the momentous machine by attempting to record songs on it for the first time in 80 years.
