Real Time FFT of speech signal using Arduino nano 33 BLE

Hello everyone,

I want to perform real time FFT of my voice signals using Arduino nano 33 BLE. Can Anyone help me with the code ?

Thanks

Mr. Internet may be helpful: Arduino nano 33 BLE + "FFT" at DuckDuckGo

Some "old" code may be AVR-centric and need some updating for newer nano.
