Hi
The code is taken from here
https://github.com/AI5GW/Goertzel/tree/main
and it has compiling errors

sounds like an issue with the IDE and the boards' definitions.

I fixed it by uploading library from linkedin page. Testing results are not good

  1. no goertzel effect = magnitude almost not depends to signal frequency.
  2. changing ADC MIDPOINT 512 to another number is not affecting
    Serial.println(Mag);

could indicate that you are using an example from this library https://github.com/AI5GW/Goertzel/tree/main
using the Goertzel.h from this library

after installing this one I have no errors,

I had errors when only the second library was installed
