consider using utils.interpolate.interp #983 (once you reviewed it...) instead of np.interp
and maybe fftfreq

[fzimmermann89]

I did a small cleanup 5132aeb pass:

• switch to interp (lets see if that works)
• use same import style as the other examples
• prefer .abs(), .mean() etc over torch.abs(), torch.mean() in some places
• typos

@ckolbPTB is that ok with you?

[fzimmermann89]

I added two small fixes to interp that I missed in #983. I am considering to have them as a seperate PR... ?

[ckolbPTB]

@fzimmermann89 great, thanks! Feel free to open a separate PR for the interp changes or just merge it here. Both is fine by me.

Then I am lazy and we keep the interp changes here
