In 2016, I finally learned OpenGL.
All the line offsetting (z-direction in time, y-direction for frequency magnitude) is now done directly in the shader. This makes the animation much smoother, as no THREE.js points/lines have to be created and destroyed anymore. It also allows more flexibility in color effects.

For a long time, I wanted to try out WebGL. After some initial research, it became clear that it is not that simple to use WebGL without having prior experience with OpenGL. Thats why I settled with THREE.js . This library abstracts away all the WebGL things and gives you a nice 3D interface.
I like the Joy Division Unknown Pleasures album cover. You can find something about its history here .

Intro # You have probably heard of the song [Equation] by Aphex Twin. It is known for having a scary face hidden in its frequency spectrum .
So I asked myself, how can I do this by myself? It is possible using a bit of matlab and basic knowledge in signal processing.
I choose a short mp3 track to modify: Cartoon (Interlude) by French House Artist SabastiAn.
