This program takes an image (in most common file formats), and uses the Inverse Fast Fourier Transform equation to convert it to a waveform, which is then written to an audio file (wav). This file can be (later) compressed as mp3 if desired.
The Fourier Transform allows us to take a measure of Time and transform to a measure of Frequency and Amplitude.
Use Sonic Visualiser to look at the waveform and spectrogram of the generated file.
Possible improvements: using Numpy’s `ifft2`, the 2-dimensional variant of IFFT, to process the entire image at once. Converting for-loops to `map` functions.
