Inconsistent power spectrograms |Sart|2 (left column) and their consistent version (right column) obtained by applying inverse STFT and STFT. The top-left spectrogram is artificially produced with random phase. The middle-left and the bottom-left spectrograms are music and speech signals with random dropout. Enforcing spectrogram consistency can be viewed as a smoothing process of the inconsistent spectrogram along both time and frequency axes
