First of all, I hope this doesn't appear to look like a shopping list recommendation or anything. I am only asking to see if anyone is familiar with the sound, and whether it meant anything at all.
When I was little, I used to watch Sesame Street a lot. There was one particular episode segment that had a sound that sort of sounded sinister because of the way in which the subharmonics were being generated, so it kind of startled me at first, but my older self is more curious about it now.
So, if the sound were an A440, I'd hear a tone of around D-140. Now add a warbling effect, and a moderate slide in pitch going down a whole step. Here is what it sounds like.
It is approximately around 10 minutes into the video, just after Elmo asks how many elephants sleep in the bed before it breaks. The drawer appears to snore during the inhalation, but I am assuming that since it is an inanimate object, it cannot actually breathe, so I wonder if the sound being made during the exhalation cycle is supposed to represent the actual drawers rattling or something.
Also, another thing to note is that I am completely blind, so I was never able to see any way of knowing whether the sound effects were synchronised to any visual indications that were going on at the same time, so if someone could also clarify what that was, I would greatly appreciate it.
