Abstract

An apparatus for determining a converted spatial audio signal, the converted spatial audio signal having an omnidirectional audio component and at least one directional audio component, from an input spatial audio signal, the input spatial audio signal having an input audio representation and an input direction of arrival. The apparatus has an estimator for estimating a wave representation having a wave field measure and a wave direction of arrival measure based on the input audio representation and the input direction of arrival. The apparatus further has a processor for processing the wave field measure and the wave direction of arrival measure to obtain the omnidirectional audio component and the at least one directional component.
