Calculate a Better FFT by Leveraging the PSD

We introduce a method to calculate a Fourier transform leveraging an averaging routine like the power spectral density. This has the benefit of allowing explicit definition of the frequency resolution and the output values are independent of time duration. This video explains the calculation method and demonstrates the benefits while also introducing a function in our open-source Python library to enable you to reproduce this easily on your own data!
