So I was flicking through the radio in my car at the Weekend, and on a whim turned to Long Wave. There was a kind of low buzzing noise that I was about to turn off when I realised it was rising and falling in pitch with the engine revs. I’m guessing the signal was being induced by the alternator.

I’m only boring you with this tedious trivia because it sounded just like the kind of tortured approximation to an engine noise that games like Stunts would try and squeeze out of your adlib card (or PC Speaker), back in the early 90s.
