Apparatus and method for synthesizing a spatially extended sound source using cue information items

[0001] An apparatus for synthesizing a spatially extended sound source, comprises: a spatial information interface (100) for receiving a spatial range indication indicating a limited spatial range for the spatially extended sound source within a maximum spatial range (600); a cue information provider (200) for providing one or more cue information items in response to the limited spatial range; and an audio processor (300) for processing an audio signal representing the spatially extended sound source using the one or more cue information items.
