Can you hear what the machine hears?

19 clips, six seconds each. Most of them my code calls either an event or the music, and for those the question is which. A few it could not call at all, and for those the question is different: what would you want said?

The task. Play each clip and decide: did something arrive — a thing happened — or did the music build up, with nothing actually happening?

Listen to what comes after the loud moment, not just the loud moment itself. That is where the two differ.

Every clip is level-matched, so loudness will not tell you the answer. If you genuinely cannot tell, say so — that is an answer, not a failure, and it is more useful to me than a guess. It takes about ten minutes.

My code could not call this one. So rather than asking which it is: what would you want said here, if anything?
