A program to take a waveform and output a spectrogram in (say) Portable
Bit Map format.  To do this, look in Sutil to find a number of programs
that do roughtly what is needed.  lpcoder.c is perhaps the simplest, it
gives you lpc coefficients for every frame in a file.  Then you need to:

  (optionally) replace the LPC by a FFT
  compute the power at every frequency by squaring and adding the real and
  imaginary components.
  Take the log of the powers
  Find the maximum number in the whole array
  Set at floor to be (say) 40 dB below the maximum
  Scale all values to be 0 for the floor or less, to 1 for the max
  Print out!
