This is a Simple Audio Spectrum Visualizer written in Python. Uses a FFT algorithm and the pygame library to display frequencies of audio data from the current default audio input. I find it useful for testing the quality of audio input equipment to make sure high frequencies are found.

iPython Notebook that goes over the theory of the DFT and FFT as well as the implementation of various radix-2 algorithms in Python
