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
