Inspired by 3Blue1Brown's video, "But what is the Fourier Transform? A visual introduction." (https://youtu.be/spUNpyF58BY), I decided to remake the DFT algorithm!
I included a few sound files. Modify minim.loadFile() in the code to change which sound file to play.
- "440hz.mp3" a simple pure 440hz tone
- "ghostchoir.mp3" a beautiful song by Louie Zong. The tones are really clean so they make a great visualization!
- "intothespiral.mp3" a jazz piece by Fox Capture Plan.
Interested in running this program?
- Download Processing (java) from https://processing.org/
- run
git clone https://github.com/koizura/DiscreteFourierTransformin the command line - open
fourierTransform.pdein the Processing editor - add the Minim library to by navigating to Sketch > Import Library > Add Library, and search for Minim and install.
- Hit play, and hopefully everything works :)
