Abstract
An apparatus comprises a receiver () receiving a multi-channel audio signal representing audio for a scene. An extractor () extracts at least one directional audio component by applying a spatial filtering to the multi-channel signal where the spatial filtering is dependent on the multi-channel audio signal. A feature processor () determines a set of features for the first directional audio component and a categorizer () determines a first audio source category out of a plurality of audio source categories for the directional audio signal in response to the set of features. An assigner () assigns a first audio source property to the first directional audio component from a set of audio source properties for the first audio source category. The apparatus may provide very advantageous categorization and characterization of individual audio sources/components present in a multi-channel signal. This may be advantageous e.g. for visualization of audio events.
