)Returns a matrix of the same dimensions as `spec` containing the guessed phase.
the spectrogram that is to be transform to a time series: numeric matrix with frequency bins in rows and time frames in columns
an initial guess at the phase: numeric matrix of the same dimensions as spec
the number of iterations of the GL algorithm (Griffin & Lim, 1984), 0 = don't run
sampling rate of x (only needed if x is a
numeric vector)
overlap between successive FFT frames, %
window type accepted by ftwindow, currently
gaussian, hanning, hamming, bartlett, blackman, flattop, rectangle
STFT step in points
if TRUE, prints estimated time left every 10% of GL iterations
if TRUE, produces a scree plot of squared error over GL iterations (useful for choosing `nIter`)
Uses the iterative method proposed by Griffin & Lim (1984) to guess the phase of a magnitude spectrogram.
