What’s on the Other Side of Your Touchscreen
What’s on the Other Side of Your Touchscreen
How is sound (and video for that matter) captured and stuffed into an iThingy? Vallancourt takes a look at the nature of sound, human hearing, and the slight of hand that allows your entire musical existence to be carried around in your pocket or streamed from “out there” somewhere. Along the way, Vallancourt will also poke into other technologies you’re probably holding in your hand at this very moment.
