Smoothing effect of spectrogram consistency applied to permutation misaligned signals: a music and b speech. The left column shows the original source signals |Sn|2, and the center column shows their randomly permuted versions, which simulates the permutation problem and is denoted as \(\boldsymbol {S}_{n}^{(\text {perm})}\). The right column shows the consistent versions of \(\boldsymbol {S}_{n}^{\mathrm {(perm)}}\). The smoothing effect mixes up the signals
