DEMO_PHASERET - Phase retrieval and phase difference
Description
This demo demonstrates iterative reconstruction of a spectrogram and
the phase difference.
Original spectrogram
This figure shows the target spectrogram of an excerpt of the gspi
signal
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.
