vitaFFT is a fast Fourier transformation (FFT) for the PS Vita, 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.
User guide
There's a little arrow and a frequency in the top left corner. These indicate which frequency the arrow is pointing at.
There's also a sensitivity value in the menu box. This just multiplies the audio input samples read by the microphone with the sensitivity value, acting a bit like an audio amplifier.
Controls
L - Show/Hide menu
Left/Right - Move the arrow
Select - Exit
