If you knew what you were doing you could have reasoned about what your code did, though. Such is the danger of trial-by-error vibe coding. I personally closed the tab because the audio kept cutting off arbitrarily after some minutes. Not to criticise you unduly because this was a cute concept, but I hope you might take away that LLMs are not only not perfect, but are also only "good enough" if your standards for "good enough" are particularly low, and use this as motivation to learn more in the future instead of always relying on them.
