I have unsuccessfully searched for some images of annotated spectrograms (of both raw spectrum and "processed" graphics) but found only one in the "Images" section on CN. Of course, there are some that show up within various threads, but those I just stumble upon. Those that do appear in discussion threads are extremely helpful though not necessarily with any helpful "Topic Tag" and, therefore, very hard to find using the search bar. (I'm not sure there is a useful tag for them, anyway.)
Maybe, I'm just not searching correctly?
Is there a source, out there, of example spectrograms that are amply annotated? Hopefully, annotated in 'simpler English' (lol), such that a beginner can start to pick up some of the jargon!
