ICEFFT

performs FFT followed by MAX/AVG frame functions for spectral analysis

<IN>	 - Input File
<OUT>	 - Output File
<NFFT>	 - FFT size (2**N)
<WIN>	 - Window function (HANN,BH92, ... FPPF, NONE)
<OVER>	 - Overlap fraction (0->1)
<NAVG>	 - Number of frames to average before output

Examples:

Switches:
  /NMAX - Number of output frames to block maximum before block averaging
  /NEXP - Number of output frames to exponential average after block averaging
  /SHIFT - Switch description
  /FLAGS - Switch description
  /TL - optional transfer length
