Fastest(?) Fourier Transform for Arduino

From piano audio to notes.

Efficiently perform arithmetic operations on large integers with hundreds of thousands of digits.

A fast Fourier transform (FFT) is an algorithm that computes the discrete Fourier transform of a sequence. Decomposing an N-point time domain signal into sequence of single points. The N-spectra are synthesized into a single frequency spectrum.
