How To Wreck A Nice Beach: The Vocoder from World War II to Hip-Hop by Dave Tompkins (Stop Smiling Books; $35) World War II increased the rate of human innovation to a pace unseen in any other period of history. New technology from the era includes everything from synthetic rubber to the atomic bomb to magnetic audio tape, which the Germans successfully kept secret until the war's end. After the Nazis fell, Lt. Jack Mullin of the US Army Signal Corps shot footage outside of Hitler's home, grabbed one of the Fuhrer's piano strings for a souvenir, and brought two AEG Magnetophons (along with fifty reels of Farben recording tape) back with him to the states. He then sold a recorder to Bing Crosby, revolutionizing broadcasting and music-making in the process. Another device that made its debut in World War II only to be later adopted by the entertainment industry is the Vocoder. Speech synthesis was the brainchild of a Bell Labs employee named Homer Dudley. Dudley surmised that human speech consisted of two things: the carrier (the noise that your vocal cords makes) and the formant (the sound formed from the carrier by your mouth, throat, and sinuses). Dudley went on to develop something called the Voder (Voice Operator DEmonstratoR), which used a carrier tone generated by a radio valve and a formant created by hissing air to create artificial speech. Hear a demonstration (and learn about how the Vocoder was used to defeat the Axis powers) after the break.
