Title: METHOD AND APPARATUS FOR PROCESSING AN AUDIO SIGNAL ASSOCIATED WITH A VIDEO IMAGE
Abstract:
An audio signal processing apparatus comprises a receiver (101) which receives an audio signal comprising audio data for at least a first audio object associated with a three dimensional image. The audio signal also comprises depth position data indicative of a target depth position for the first audio object. A determiner (107) determines a visual rendering depth range for a target three dimensional display for presenting the three dimensional image and a mapper (109) for mapping the target depth position to a rendering depth position for the audio object where the mapping is dependent on the visual rendering depth range. The visual rendering depth range may specifically be a depth range in which the three dimensional display can accurately render objects and the mapper (109) may amend the positions of audio object sound sources such that these match the depth positions of corresponding visual objects presented by the three dimensional display.
