From there, another Python script filters the captured waveform, applies a window function, calculates the Fourier transform and plots the spectrum into a graph.

A faster transform means that less computer power is required to process a given amount of information—a boon to energy-conscious mobile multimedia devices such as smart phones.

The code is in Python and uses numpy’s fast Fourier transform to identify digits.
