It sounds like a slipping auxiliary belt. Spray some water on the grooved part of the belt and if the noise gets worse then this confirms it. If the noise goes then either the belt tensioner or idler are faulty. If there is no change then the fault is elsewhere. You are well overdue for a timing belt change though.
If it wasn't the aux belt and was something like the timing belt tensioner, "waiting for something to happen" could be pretty terminal!
