Modern stereophonic technology was invented in the 1930s by British engineer Alan Blumlein at EMI, who patented stereo records, stereo films, and also surround sound. [7] In early 1931, Blumlein and his wife were at a local cinema.
In 1931, Blumlein invented what he called "binaural sound", now known as stereophonic sound. [2] In early 1931, he and his wife were at the cinema. The sound reproduction systems of the early talkies only had a single set of speakers – the actor might be on one side of the screen, but the voice could come from the other. Blumlein declared to ...
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 ...
The first system for creating stereophonic sound (using telephone technology) was demonstrated by Clément Ader in Paris in 1881. The pallophotophone, invented by Charles A. Hoxie and first demonstrated in 1922, recorded optically on 35 mm film.
Over the next two years, Blumlein developed stereo microphones and a stereo disc-cutting head, and recorded a number of short films with stereo soundtracks. In the 1930s, experiments with magnetic tape enabled the development of the first practical commercial sound systems that could record and reproduce high-fidelity stereophonic sound. The ...
Two bi-directional AKG C414 microphones set up in a Blumlein pair. Blumlein pair is a stereo recording technique invented by Alan Blumlein for the creation of recordings that, upon replaying through headphones or loudspeakers, recreate the spatial characteristics of the recorded signal.
Some AV receivers, stereophonic systems, ... Ambisonics was invented by Michael Gerzon. Binaural recording. Binaural recording is a method of recording sound that ...
Harvey Fletcher (September 11, 1884 – July 23, 1981) was an American physicist. [1] Known as the "father of stereophonic sound", he is credited with the invention of the 2-A audiometer [2] and an early electronic hearing aid.
