Note:
The proposed algorithm is compared with the Griffin-Lim algorithm (GLA) [1] and the fast GLA (FGLA) [2].

In the letter, we used utterances in "TIMIT Database" contained in the "PhaseLab Toolbox" [3], and the babble noise in "NOISEX-92" [4].
Due to the licence, an utterance in "CMU Arctic Databases" [5] and the Gaussian noise are used in this example script.

The reconstructed signals were evaluated by PESQ [6], STOI [7], and the spectral convergence [8].
For evaluating PESQ and STOI, "pesq2" in "PhaseLab Toolbox" [3] and "taal2011" in "Auditory Modeling Toolbox" [9] were used.
Please download and i those toolboxes.

Note that we use our "STFT" and "iSTFT" for publishing this example script.
However, for the experiment in the letter, "Large Time-Frequency Analysis Toolbox" [10] was used for STFT and iSTFT.
