Spectrogram quality

[JuanFMontesinos]

Hi,
I've testing your code and it reconstruct your stft.
I'm afraid this is librosa stft

And this is the spectrogram computed with this method

[JuanFMontesinos]

Well, to be constructive you can fix it with the hanning window from scipy
scipy.signal.get_window("hanning", nfft)

These should be the same now, within some margin of error. Still having an issue with getting the phases to match perfectly though.
