How the arrival of stereo changed the way we experience sound

The advent of stereo dramatically changed our experience of sound. St. Louis audiophile David MacRunnel provides a primer on that audio development: how it works, why it took off in the U.S. in particular, and what makes stereo different from — not necessarily better than — monophonic sound. MacRunnel and his partner Katie Cahill will talk in-depth about stereophonic tech, show early-era equipment, and play full albums by Miles Davis, the Beatles, and the Reiner/Chicago Symphony Orchestra at the St. Louis Science Center’s 21+ event “Up Late: Experience Sound” on July 25. *This episode is best listened to with headphones or earbuds, or in a car with dual speakers.
