ABSTRACT:
An audio user interface is provided in which items are represented in an audio field by corresponding synthesized sound sources from where sounds related to the items appear to emanate. The interface is generated by apparatus that includes functionality for determining for each sound source, a rendering position at which the sound source is to be synthesized to sound in the audio field. To facilitate discrimination between the synthesized sound sources, the sound-source rendering positions are adjusted such that the audio field is dilated in a region of the audio field about a focus reference; this focus reference is, for example, the current direction of facing of the user or the position of an audio cursor in the audio field.
