Simply choose a setting from the three shown when run and enjoy a hearty Fourier Transform. The green sections show the area around each of the frequencies the wave includes - there should be a spike in the middle of each one (it may be off to the side if using Beauty as it is not as accurate). Press the black button to activate the more frequencies option, which will make the wave more complicated, resulting in more spikes in the transform. May require to be run on Lag Central to ensure success.
Setting guide: Beauty - a simple Fourier transform with minimum accuracy settings but optimized for beauty. Math - Settings optimized for a mixture of speed and accuracy, suitable for an average computer. Lag Central - Is your computer overpowered, or are you looking for a way to really lag it? Well, why not produce a very accurate Fourier Transform while you're at it (if the Sun hasn't turned into a red giant by the time it gets to the second spike).
