this is getting really interesting.
Not really, it's pretty basic stuff. As I said before, you cannot send a pointer to an array of integers to a function that expects a pointer to an array of doubles. The types are totally different so your program would just be processing garbage. I showed you in my previous message how to pass the array of integers to the function that needs the values as doubles. That is all there is to it, the compiler will generate the correct code to convert each integer to a double as you process them. The resulting double values can then be used in your FFT calculations.
