We have presented a paper at the 5th International Symposium on Communications, Control, and Signal Processing. It discusses the influence of spatial bandlimitation in modal beamforming when used as plane wave decomposition for binaural synthesis. Besides the instrumental measures given in the paper/presentation you can also download a series of listening examples. The samples have been computed for the parameters described in the paper. The maximum order N of the spherical harmonics expansion has been varied, as well as the head rotation (incidence angle of the virtual source). As source material noise bursts, speech and castanets have been used. The examples are provided as binaural sound files optimized for the AKG K-601 headphone. The file names encode the conditions and incidence angle.
