Abstract
An apparatus for processing audiovisual data for a scene comprises a receiver (201) for receiving audiovisual data for the scene. The audiovisual data comprises audio data for the scene comprising a plurality of audio elements and image data for at least a first image of the scene where the first image has a first aspect ratio. An image remapper (203) performs a content dependent non-uniform mapping of the first image to a second image which has a different aspect ratio. The image remapper (207) is arranged to generate mapping data describing the content dependent non-uniform mapping. An audio remapper (207) replaces a first audio element of the plurality of audio elements by a second audio element generated by modifying a spatial property for the first audio element in response to the mapping data. The spatial property being modified may be a position and/or spatial spread of the first audio element.
