Spookiest thing that’s happened to me since I saw the flying saucer on the Pennsylvania Turnpike (but that’s another story):
I was just getting settled in to the recording booth to read Ben Bernanke’s macroeconomics textbook for undergraduates (which promises to be the best such that I’ve recorded) and Kathryn was there to check my recording level. She likes to play back the previous reader to make sure that there’s not a big jump in levels between readers. The previous reader had a nice rumbly, confident baritone; he sounded to be a bit older than me. So his track ran out and I said, “Well, that’s a very reassuring voice.” And then, in a snap, his voice returned on the headphones to say, “Thank you, sir.”
Of course, what it was was his version of “Okay, monitor, we’re finished recording for today.” But Kathryn and I played it back again to make sure that the booth hadn’t acquired a haunt.
