FIELD: physics.
SUBSTANCE: improved processing of an audio signal can be achieved, if audio signals are converted to directional components. In other words, the present invention shows that improved spatial processing can be achieved, when the format of a spatial audio signal corresponds to directional components as recorded, for example, by a B-format directional microphone. Furthermore, the present invention shows that directional or omnidirectional components from different sources can be processed jointly and therewith with an increased efficiency. In other words, especially when processing spatial audio signals from multiple audio sources, processing can be carried out more efficiently, if the signals of the multiple audio sources are available in the format of their omnidirectional and directional components, as these can be processed jointly. In embodiments, therefore, audio effect generators or audio processors can be used more efficiently by processing combined components of multiple sources.
EFFECT: improved spatial processing of an audio signal.
