Comparison of Spatialization Techniques with Different Music Genres II

The main characteristics of a good spatialization algorithm are that the resulting sound image is enveloping, stable, clear. Such a sound image would then not only give a good sense of immersion to the listener but will also enable the listener to clearly localize the different sound elements, and ideally move around or at least have freedom to move the head and not have any major distortions in the listening experience. Part 1 of this study compared three algorithms, Ambisonics, VBAP and DBAP with four different music genres. In part 2, a more in-depth analysis is done of the results found in part 1. Binaural recordings done using a Neumann KU100 dummy head are used to compare the results found in the loudspeaker study with attributes found in the recordings. It was seen how more bright, next spectrally complex and more spectrally flat signals could have resulted in the user ratings.
