Édouard-Léon Scott de Martinville invented a way to document sound more than a decade before Thomas Edison developed his wax cylinders. So why isn’t he remembered as the king of recording? Because he hadn’t figured out one key feature: playing the sound back. Plus: ever wondered what it’s like inside an anechoic chamber, which masks almost every sound possible? Really quite and kind of freaky.
