how do I fftshift my complex spectrogram?

I'm looking at complex-valued radio signals caught from my SDR and normally process spectrograms in their human-understandable (fftshift'd) form.

Here's what scipy produces:

and, here's what I get with pytftb:

Is there a simple way to make everything conformant?

Thanks,

Hi @rcox771

The idea is to (sometime in the near future) get rid of tftb's STFT implementation (#156 ) and use scipy's implementation. When we do that, it will fix the spectrogram too.

I'll notify this thread when this is done.
