Original Abstract Submitted
According to an example embodiment, a technique for processing an input audio signal comprising a multi-channel audio signal is provided, the technique comprising: deriving, based on the input audio signal, a first signal component comprising a multi-channel audio signal that represents a focus portion of a spatial audio image conveyed by the input audio signal and a second signal component comprising a multi-channel audio signal that represents a non-focus portion of the spatial audio image; processing the second signal component into a modified second signal component wherein the width of the spatial audio image is extended from that of the second signal component; and combining the first signal component and the modified second signal component into an output audio signal comprising a multi-channel audio signal that represents partially extended spatial audio image.
