     The definition of the von Mises distribution should include \phi - \mu, not \phi + \mu.
     Correspondingly, the phase random varaible defined in the next equation should be:
     		      \bf{\theta}_\nu = -\nu \omega_0 {\bf \tau}_k + \bf{\phi}_\nu

     Figure 2-4 (a) needs to be reflected about the x-axis (corresponding to the sign error on page 28).

    \kappa_\nu = \frac{C}{2} |\hat{G}(j\nu\omega_0)|
    The factor of two comes from not including the corresponding negative values of \nu in the summation.
    For the PHAT filter \kappa_\nu = \frac{C}{2}.
