Claim 0:
1. An apparatus comprising:
a receiver for receiving a multi-channel audio signal representing audio for a scene;
an extractor for extracting at least a first directional audio component by applying a spatial filtering to the multi-channel signal, the spatial filtering being dependent on the multi-channel audio signal;
a feature processor for determining a set of features for the first directional audio component;
a categorizer for determining a first audio source category out of a plurality of audio source categories for the first directional audio component in response to the set of features, each audio source category of the plurality of audio source categories being linked to a set of one or more audio source properties; and
an assigner for assigning a first audio source property to the first directional audio component from a set of one or more audio source properties linked to the first audio source category, wherein the extractor comprises:
a divider for dividing audio channel signals of the multi-channel audio signal into a plurality of frequency interval signal components;
a direction estimator for determining a direction for each frequency interval signal component of the plurality of frequency interval signal components;
a grouper grouping frequency interval signal components into groups in response to the directions for each frequency interval signal component; and
a generator for generating the first directional audio component by combining the frequency interval signal components of a group of frequency interval signal components,
wherein the apparatus further comprises an image generator for generating an image of the scene; and wherein the image generator is arranged to include a graphic element in the image, a property of the graphic element being dependent on the first audio source property, and
the apparatus further comprises an audio processor for generating an output audio signal from the multi-channel audio signal, the audio processor being arranged to adapt a processing of the multi-channel audio signal in response to the first audio source property.
