Alan Blumlein who is acknowledged as the inventor of binaural and stereo recording is to be awarded a posthumous Grammy Award for Technical Merit by The Recording Academy later this year.
A Prolific Inventor And Engineer
Alan Dower Blumlein who was born on 29th June 1903 and died on 7th June 1942 was an English electronics engineer, notable for his many inventions in telecommunications, sound recording, stereophonic sound, television and radar, but is probably best known as the inventor of stereo recording. Although his life was cut short, he received 128 patents and was considered as one of the most significant engineers and inventors of his time.
A Tragic Accident
He died during World War II on 7 June 1942, aged 38, during the secret trial of an H2S airborne radar system then under development, when all on board the Halifax bomber he was flying in were killed when it crashed at Welsh Bicknor in Herefordshire.
Television Too – Not Just Sound
Blumlein was also largely responsible for the development of the waveform structure used in the 405-line Marconi-EMI system which became the UK’s BBC Television Service at Alexandra Palace, becoming the world’s first scheduled “high definition” (240 lines or better) television service.
A Engineer’s Test
Above is a film made by Alan Blumlein, the inventor of stereo sound, to demonstrate his creation whilst he was working at EMI. Alan lodged the patent for what he called ‘binaural’ sound in 1931, in a paper which patented stereo records, stereo films and also surround sound. He and his colleagues made a series of experimental recordings and films to demonstrate the technology.

#wecando MAKING OF
In a movie we recreate all the sounds, the only thing that we use is the direct sound – the voices, from the film set.
Ambiences is something very important and there are 2 techniques that I like to use to create and make it believable and fit on a scene. Reverbs is very important for this.
The first trick use reverbs to give depth for the ambience, especially for some birds, animals, etc! This is a very good way to mix some layered ambiences without masking the others effects.
The second is use reverb to process the ambience to fit on the scene, using a convolution reverb is a nice way to get the right sound of the room, when you don’t have a way to record that room!
Some convolution reverbs also allows to you create a impulse response with the slate claps, that helps even more to get the right sound for the room what was recorded the scene.
