Invention of Stereo Sound Reproduction, 1931
Alan Dower Blumlein filed a patent for a two-channel audio system called "stereo" on 14 December 1931. It included a "shuffling" circuit to preserve directional sound, an orthogonal "Blumlein Pair" of velocity microphones, the recording of two orthogonal channels in a single groove, stereo disc-cutting head, and hybrid transformer to mix directional signals. Blumlein brought his equipment to Abbey Road Studios in 1934 and recorded the London Philharmonic Orchestra.
