  50 How to generate these data:
  51
  52 1. You need the MIT Media Lab's KEMAR data, read it into an software
  53    capable of signal/time series analysis (like Mathematica, Matlab,
  54    ...)
  55
  56 2. Construct an equalizing FIR inverse filter by calculating the
  57    transfer function of the front, same side impulse response, then
  58    take 1 over the absolute magnitude.
  59
  60 3. Cut the poles in the inverse filter's transfer function
  61    specification by limiting the amplification to 2.5 (note, this
  62    number assumes that you have correct signal processing
  63    normalization of the Fourier transform).
  64
  65 4. Design the FIR inverse filter by calculating the inverse Fourier
  66    transform, then chopping the coefficients down to a reasonable
  67    number (N = 15 is used here), apply the Kaiser-Bessel window (alpha
  68    = 2 is used here).  Note the objective is remove the color bias
  69    only (as if you are using an equalizer), _not_ to do a full inverse
  70    filtering. (Note: beta = pi*alpha in other notation.)
  71
  72    For N = 15, alpha = 2, you should get the following impulse
  73    response:

  80
  81 5. Linearly convolve all KEMAR HRIR with this inverse filter.
  82
  83 6. Resample from 44.1 kHz sampling frequency to 48 kHz.
