  51 /* EQUALIZED KEMAR HRIR
  52
  53 How to generate these data:
  54
  55 1. You need the MIT Media Lab's KEMAR data, read it into an software
  56    capable of signal/time series analysis (like Mathematica, Matlab,
  57    ...)
  58
  59 2. Construct an equalizing FIR inverse filter by calculating the
  60    transfer function of the front, same side impulse response, then
  61    take 1 over the absolute magnitude.
  62
  63 3. Cut the poles in the inverse filter's transfer function
  64    specification by limiting the amplification to 2.5 (note, this
  65    number assumes that you have correct signal processing
  66    normalization of the Fourier transform).
  67
  68 4. Design the FIR inverse filter by calculating the inverse Fourier
  69    transform, then chopping the coefficients down to a reasonable
  70    number (N = 15 is used here), apply the Kaiser-Bessel window (alpha
  71    = 2 is used here).  Note the objective is remove the color bias
  72    only (as if you are using an equalizer), _not_ to do a full inverse
  73    filtering. (Note: beta = pi*alpha in other notation.)
  74
  75    For N = 15, alpha = 2, you should get the following impulse
  76    response:

  83
  84 5. Linearly convolve all KEMAR HRIR with this inverse filter.
  85
  86 6. Resample from 44.1 kHz sampling frequency to 48 kHz.
