Abstract
Apparatus for adapting a spatial audio signal for an original loudspeaker setup to a playback loudspeaker setup that differs from the original loudspeaker setup. The apparatus includes a direct-ambience decomposer that is configured to decomposing channel signals in a segment of the original loudspeaker setup into direct sound and ambience components, and to determine a direction of arrival of the direct sound components. A direct sound renderer receives a playback loudspeaker setup information and adjusts the direct sound components using the playback loudspeaker setup information so that a perceived direction of arrival of the direct sound components in the playback loudspeaker setup is substantially identical to the direction of arrival of the direct sound components. A combiner combines adjusted direct sound components and possibly modified ambience components to obtain loudspeaker signals for loudspeakers of the playback loudspeaker setup.
