When you listen to an audiobook on an iPod, the default scanning speed is, of course, “1x,” which means that the audio plays at normal speed. But there is also a “2x” button that allows you to play the audio back twice as fast as it was recorded — without changing the pitch. It takes a little while to get used to the increased pace, and there are some unnatural tonal artifacts that sound strange, but when you’re listening to an educational book or anything you want to get through quickly it’s incredibly efficient. After a few minutes, the artificiality falls away and your ear and brain make the adjustment on the fly.
But then you find yourself throughout the day stuck in normal-speed conversations, and sometimes you start looking at people’s foreheads and wishing you could find that little 2x button.
