I remember some years ago I saw a YouTube video of a guy who did a recreation of this in some sort of Audio Programming Language (it might have been SonicPI or something).

He started off by claiming he wanted to create the sound of a hundred bees or something, then he coded these, and bit by bit he re-created the Deep Note. Since the video wasn't titled after that, it was quite a surprise.

I can't seem to find that video anymore, if anyone has a link, please share it :)
