1 janv. 1931 - 1931 – Alan Blumlein develops binaural sound

Description:

Alan Blumlein develops binaural sound (now known as stereo sound) at the Central Research laboratories at the EMI site in Hayes. After a night at the cinema Blumlein was frustrated that the sound from a character on screen could only be heard from a speaker at the other side of the room. To solve this problem, he invented the audio stereo system which is still in use today. He began by removing the idea that two loudspeakers represented the listeners’ two ears and instead sought to re-create the features of the sound field including directional information.
