Classification: CPC H  G | IPC H

Claim 11:
12. A method comprising:
receiving a multi-channel audio signal representing audio for a scene;
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;
determining a set of features for the first directional audio component;
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
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 extracting comprises:
dividing audio channel signals of the multi-channel audio signal into a plurality of frequency interval signal components;
determining a direction for each frequency interval signal component of the plurality of frequency interval signal components;
grouping frequency interval signal components into groups in response to the directions for each frequency interval signal component; and
generating the first directional audio component by combining the frequency interval signal components of a group of frequency interval signal components,
generating an output audio signal from the multi-channel audio signal, by an audio processor arranged to adapt a processing of the multi-channel audio signal in response to the first audio source property, and
generating an image of the scene by an image generator arranged to include a graphic element in the image, a property of the graphic element being dependent on the first audio source property.
