Abstract DirAC is an established method to improve the perceived direction of arrival. Up to now this method has been particularly described for VBAP. The drawback of this method is that the positions of the loudspeakers must be previously known. In this thesis the DirAC method has been described for Higher Order Ambisonics, which has multiple advantages, one of them being that the DirAC algorithm can also be used without any knowledge about the loudspeaker configuration. Furthermore, a frequency analysis method, that is adapted to the human auditory system, has been used (CQT).
