  69 /* EQUALIZED KEMAR HRIR
  70
  71 How to generate these data:
  72
  73 1. You need the MIT Media Lab's KEMAR data, read it into an software
  74    capable of signal/time series analysis (like Mathematica, Matlab,
  75    ...)
  76
  77 2. Construct an equalizing FIR inverse filter by calculating the
  78    transfer function of the front, same side impulse response, then
  79    take 1 over the absolute magnitude.
  80
  81 3. Cut the poles in the inverse filter's transfer function
  82    specification by limiting the amplification to 2.5 (note, this
  83    number assumes that you have correct signal processing
  84    normalization of the Fourier transform).
  85
  86 4. Design the FIR inverse filter by calculating the inverse Fourier
  87    transform, then chopping the coefficients down to a reasonable
  88    number (N = 15 is used here), apply the Kaiser-Bessel window (alpha
  89    = 2 is used here).  Note the objective is remove the color bias
  90    only (as if you are using an equalizer), _not_ to do a full inverse
  91    filtering. (Note: beta = pi*alpha in other notation.)
  92
  93    For N = 15, alpha = 2, you should get the following impulse
  94    response:

 101
 102 5. Linearly convolve all KEMAR HRIR with this inverse filter.
 103
 104 6. Resample from 44.1 kHz sampling frequency to 48 kHz.
