Octave Visualizer 
A realtime harmonic music visualizer written in C++. 

This visualizer takes in any audio input and in realtime produces a colorful visualization of an octave wrapped cyclically. It works very similarly to the harmonic analysis made in my experiments with generative music the semester before. I think it is quite musical, as opposed to visualizers that just display the Fourier transform.
