If you turn on your radio in London these days, you are likely to hear a spot describing how, if you spend more than three pounds and buy a certain kind of chocolate (no purchase necessary sic) at an Esso Snack & Shop, you could end up winning a shopping spree in New York. Sounds pretty ordinary so far. But as you listen, you begin to notice that the announcer is gradually morphing from a British guy into a New Yorker (and, by the way, that the birds chirping in the background are being transformed into police sirens). Whatever else this ad might tell us about British perceptions of New York, it is just one of several examples of the amazing audio morphing work being done by Pete Johnston, technical manager and Kyma guru at The Tape Gallery, a London studio specializing in sound design for advertising.
