摘要： Apparatus (100) for adapting a spatial audio signal (2) for an original loudspeaker setup to a playback loudspeaker setup that differs from the original loudspeaker setup. The apparatus comprises a direct-ambience decomposer (130) that is configured to decomposing channel signals in a segment of the original loudspeaker setup into direct sound (D) and ambience components (A), and to determine a direction of arrival of the direct sound components. A direct sound renderer (150) receives a playback loudspeaker setup information and adjusts the direct sound components (D) 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 (180) combines adjusted direct sound components and possibly modified ambience components to obtain loudspeaker signals for loudspeakers of the playback loudspeaker setup.
