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.

摘要： An apparatus (100) for converting an object position of an audio object from a cartesian representation (110) to a spherical representation (112) is described. A basis area of the cartesian representation is subdivided into a plurality of basis area triangles (630,532,634,636), and wherein a plurality of spherical-domain triangles (660,662,664,666) are inscribed into a circle of a spherical representation. The apparatus is configured to determine, in which of the basis area triangles a projection (P) of the object position of the audio object into the base area is arranged; and the apparatus is configured to determine a mapped position (I) of the projection (P) of the object position using a linear transform (II), which maps the base area triangle onto its associated spherical domain triangle. The apparatus is configured to derive an azimuth angle (φ) and an intermediate radius value (IV) from the mapped position (I). The apparatus is configured to obtain a spherical domain radius value (V) and an elevation angle (III) in dependence on the intermediate radius value (VI) and in dependence on a distance (z) of the object position from the base area. An apparatus for converting an object position of an audio object from a spherical representation to a spherical representation, applications of these apparatuses, methods and computer programs are also described.
