Librosa spectrogram

PyTorch Spectrogram Inversion Documentation¶ A major direction of Deep Learning in audio, especially generative models, is using features in frequency domain because directly model raw time signal is hard. But this require an extra process to convert the predicted spectrogram (magnitude-only in most situation) back to time domain.
