This webpage provides demonstration audio samples, accompanying the paper as
discussed in the "Experiments" section. GL Positive and GL ZeroMean
refer to the GriffinLim
algorithm when applied to spectrograms derived from positive signals and
zeromean signals respectively. Hop Size specifies the number of samples
between the start of adjacent STFT analysis windows. A smaller hop size implies
greater redundancy in the STFT, so that the corresponding spectrogram provides
more information about the original signal. Each STFT was computed with
rectangular (boxcar) windows. Note that the success of this algorithm strongly
depends on the use of a rectangular window. If your processing requires the use
Hamming/Hanning or other nonrectangular windows to compute the STFT, the methods
described herein will probably not give good results.
