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.

The residual projection data processor (101; 201; 301) is configured to determine residual projection data (I) by cancelling reference projection data (II) from measured projection data (III). The measured projection data (III) represents a measured projection of a test object under examination obtained by an imaging modality. The reference projection data (II) represents a projection of a reference object. The image reconstruction unit (102; 202; 302) is configured to reconstruct a resulting residual image (IV) on the basis of the residual projection data (I) by solving an inverse projection transformation problem that links the residual projection data (I) to the resulting residual image (IV). The resulting residual image (IV) represents differences between the reference object and the test object under examination. A corresponding method is also described.
