That looks amazing. It would be very nice to have the .ino file to use in other Projects :) |

If you are looking for an easy way to do FFT I can recommend my audio-tools library |

I made a fast and accurate spectrum analyzer. You can actually tell which note is playing.
I'm doing Fourier analysis with 4096 samples with 85% overlap. I get 70 fps. The accuracy comes from the Kaiser 3 windowing I do before the FFT.
This is just a prototype. I'll be adding features one by one but the algorithm is done.
Thank you for an amazing library <3
I've had a great deal of fun with it in the last two months.
