Abstract
Loudspeakers in domestic or automotive environments are rarely placed ideally with respect to the sources supplying them, and the stereo and surround images are seldom satisfying. According to the invention there is provided a method and apparatus for combining a precise knowledge about the relative positions of the loudspeakers that were intended (the virtual loudspeakers) and a precise knowledge about the actual placement of listening loudspeakers into a vector space that enables calculation of running corrections to the signals used in order to simulate the presence of the virtual loudspeakers. Specifically the corrections may comprise gain/attenuations determined based on the distances in vector space between the virtual and actual loudspeakers and delays determined from these distances.
