The Spatial Race & the forgotten genius who invented stereo

 In the 1960s, stereo sound revolutionized the music industry. But it turns out, a pioneering engineer named Alan Blumlein had actually invented stereo a full three decades earlier. Due to tragic events in World War II, his innovations were forgotten for decades. In this episode, we worked with OnePlus to tell the story of how audio has evolved from mono, to stereo, to quadraphonic, to surround sound and beyond. Today, we even have immersive, three-dimensional systems that can simulate 128 speakers using just two. Featuring Alan Blumlein’s son Simon Blumlein, and sound engineer Robin Reumers from the Abbey Road Institute.
