# vitaFFT


This is a Fast Fourier Transform PoC for PSVita using my libFFT for the FFT algorithm.
The audio samples are read throught the internal microphone of the PSVita.

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
- ~~Determine the unit of the amplitude (dB, ...)~~ - FIXED in libfft
- ~~Change Y scale depending on what is being shown (dB or magnitude)~~ - DONE in main.c

## Dependencies

Install vitasdk through vdpm.
