Hi wlacerda,
Nice work! Superimposing the FFT with yellow is very well done. This FFT really works great!
Some suggestions for improvement:
- the frequency at the bottom left (nicely in yellow) always displays Hz, but can be also KHz;
- the FFT amplitude varies with input amplitude. Can the value be displayed relative in dB?
And now we wait for someone to integrate this in the latest version or someone who writes a boot-laoder that let the user choose which application to boot. That would be really awesome.
