%DEMO_JELFS2011  Binaural speech intelligibility advantage
%
%   DEMO_JELFS2011 will plot the output of the
%   jelfs2011 binaural speech intelligibility advantage model for a
%   target azimuth angle of 0 deg. The masker position will move over a
%   full circle in the horizontal plane, and the output is visualized on
%   a polar plot. The KEMAR HRTF dataset is used.
