This homebrew is a fast Fourier transformation (FFT) for the PSVita, which uses the internal microphone to read audio, formerly known as audio spectrum analyzer.

The FFT is setup as a 512 point FFT, see the libfft to know how to increase or decrease the points.

TODO

• Fix amplitude value so it isn't longer than the height of the screen.
