Here's an audio visualiser I made for a university class. The source code is available here: https://github.com/samuellapointe/Pro...

Information from the latest video:
I used Processing 3 and the minim library to visualise music.

The white lines in each corner act as a band spectrum thing. The cubes and the lines on the sides move in accordance to the overall volume of the track at that moment.

The color on the sides and cubes is determined as a RGB mix where red is low sounds such as bass, green is mid sounds and blue is high sounds. When all sounds are presents at once, it looks white. The bounds for these values were set according to what looks kinda nice.
