Some time ago a stumbled upon the concept of a fractional fourier transform (FrFt). I was really fascinated but it is hard to find good examples online.

I have already implemented various signal processing related visualizations [1] and also got some positive feedback on HN [2].

After learning about the FrFt I reimplemented my fourier cube tool and now added a feature to interpolate smoothly between time and frequency domain [3].

Hope you like it.
