The wrong frequencies on the frequency axis really aren't necessary. It doesn't make it more complex if you put the real frequency values the and it is less confusing to people who know that sound below 20hz roughly is never audible.

Otherwise, great site! I think it is great that Fourier was basically explained without mentioning his name.

The biggest problem was that the waveforms are animated in some parts, and they actually move in-speed (so 1Hz does 1 cycle a second). If it was, say, 50Hz, the inaccuracy would shift so that it was moving at 1/50th speed, and that seems harder to explain (even here, I'm not sure if my explanation makes sense!)

And yeah, hah. My goal was to not mention his name anywhere, since "fourier transforms" just sounds scary and jargony.
