Pretty much, Ive tried the other examples and none of them work

Yeah, that specific one doesn't work so well but apart from it, does any other example not work?

The Fourier transform audio examples fooled me. The example sounds and slider for them appeared consistent as far as I could tell... but then again I don't know much about Fourier transforms.

Maybe I'm out of the loop but have to say this is the first time I have seen an LLM generate a webpage with working audio widgets.

yep, i was pretty surprised by audio widgets too.
