OF Sound Visualizer with & without FaceTracking

For my CCLAB OpenFrameworks Final, I wanted to make something with similar concept as my previous Arduino project. So I'm exploring how to make Sound Visualizer in OpenFrameworks using Fast Fourier Transform (FFT) library and a couple of other addons. Here's what I've got so far:

Keyboard shortcut:
f = toggle fullscreen
w = toggle wireframe/full mesh
m = toggle audio input: between Microphone and prebuilt .wav song
z = toggle visual output: between ofMesh Sphere and ofxVideoGrabber
1-7 = change ofMesh SetMode.

Addons: ofxGui, ofxFFT. 

As the second experiment, I tried using the ofxFaceTracker to extract only the face from the live ofVideoGrabber background. In the end I wanted to make the face mesh's vertices to move according to the audio, but I haven't been able to implement it 100%. Oh well, but I had fun!

Addons: ofxGui, ofxFaceTracker, ofxFFT, ofxCv, ofxOpenCv.
