Exactly that one, yes. Well, I can't view that URL from here, but that integer is in the MP3's filename. Case closed! There's a lady's / small persons's voice admonishing someone for make noise with what sounds like a screen door part way through. It's not in English that I can tell. Do let me know if you understand what they say. I'm assuming it's just "shut up, recording!"

There is a Reply All episode about something exactly like what you describe [1]. It's been a while since I've listened to it, but it's something about how making sounds like these is a whole business with resellers upon resellers. They dive into the process and try to track down the person who made a specific recording that also had some background noise that seemed particularly weird.
