ABSTRACT:
The invention relates to a method, a system, a module, an electronic device and to a computer program product for widening a two-channel input. Two audio channels are input and filtered by equalizing said channels. The filtered channels are mixed with their opposite channels in a cross-talk network and output from loudspeakers and by this providing a spatial impression for audio.
