<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
