Hi Tormod Many thanks for your explanation and hints.
In the meantime I’ve tested some FFT software. Now the question is: Could I use one of the FFT software and use Python to take out values of the FFT software and program my own visualization in Python... Or does Python packages exists (FFT package) to “read” the frequencies and I program the graphic. I will search for that kind of package. Or do I have to write the whole stuff... Still, any hint is welcome ☺ Best regards, Jonas ------------------------------------------------------------------------------ How fast is your code? 3 out of 4 devs don\\\'t know how their code performs in production.
