DEMO_PHASERET Phase retrieval and phase difference This demo demonstrates iterative reconstruction of a spectrogram and the phase difference. Figure 1: Original spectrogram This figure shows the target spectrogram of an excerpt of the gspi signal Figure 2: Phase difference This figure shows a difference between the original phase and the reconstructed using 100 iterations of a Fast Griffin-Lim algorithm. Note: The figure in the LTFAT 2.0 paper differs slightly because it is genarated using 1000 iterations.
