DEMO_FRSYNABS  Construction of a signal with a given spectrogram

  This demo demonstrates iterative reconstruction of a spectrogram.

  Figure 1: Original spectrogram

     This figure shows the target spectrogram

  Figure 2: Linear reconstruction

     This figure shows a spectrogram of a linear reconstruction of the
     target spectrogram.

  Figure 3: Iterative reconstruction using the Griffin-Lim method.

     This figure shows a spectrogram of an iterative reconstruction of the
     target spectrogram using the Griffin-Lim projection method.

  Figure 4: Iterative reconstruction using the BFGS method.

     This figure shows a spectrogram of an iterative reconstruction of the
     target spectrogram using the BFGS method.

  The BFGS method makes use of the minFunc software. To use the BFGS method, 
  please install the minFunc software from:
  http://www.cs.ubc.ca/~schmidtm/Software/minFunc.html.
