for my next homebrew game i'm looking for a way to transform an raw WAV data to an information that can be used to create a graphic equalizer.

I will be gratefull if anyone can share with me how WAV files are built, and how can i convert a WAV to a set of numbers i can later transform to graphicl "bars" .

Fast Fourier Transform: (conversion to frequency spectrum)

its a fairly involved topic.. too much to discuss here..
