The ESP32 variant, can display a flat response between 50Hz and 20Khz and is less limited by ADC conversion time and uses 512 samples for improved resolution. It could be optimised even further for a wider freqencuy response.

To load the Arduino FFT library:
|
|
1. In the IDE menu, select Sketch, Include Library, Manage Libraries, then search for 'FFT'
