This is absolutely brilliant for educational uses. Even the front-page filter example is something I plan to suggest to my prof for the DSP class he teaches.

I'd like to suggest that in the case of audio, adding the ability to experience changes aurally in addition to visually.

That page does allow you hear the changes. See the toggle-switch next to the picture of the guitar.

"That page..." - which?

Turn on the guitar then go back up to the graph and change it. As you drag you hear its effect on the audio.

The page linked by the headline? I see no guitar on that page.

EDIT: So now I see markbao's comment[1] referencing a page[2] with a guitar on it. His comment was not in the top of my window when I was perusing earlier. In this thread of comments, there is no reference directly to the Explorable Explanations page, thus I was wondering when my sanity plummeted (since there's no guitar icon on the Tangle page).

While the Explorable Explanations page is darn nifty, in my original comment I did not clearly communicate my actual intent. To clarify: If Dr. Prof. will be incorporating such things into his lectures and course media, I suggest that he also provide the reactive aural experience to reinforce the material.
