Has anyone here created an Add On for a Fast Fourier Transform I need to see vibration data in the frequency domain and an FFT seems like a good idea. If you're wonder why... I'm looking for harmonics. I'm not sure if I want to tackle it and I'm not sure if it's even possible. N would be something like 250 at 20ms sample rate. Not too overwhelming but transforming then purging and restarting the routine ... idk. Seems daunting but might not be that bad. Thoughts?
