It either introduces frequency-dependent phase or amplitude differences in a pair of loudspeaker signals. We evaluate how the perceptual effect is influenced by off-center listening positions in a standard ±30° loudspeaker setup. The evaluation of the phantom source widening effect is based on measurements of the inter-aural cross-correlation coefficient (IACC), which is justified by its pronounced correlation to the perceived phantom source width in prior listening test results.}, type={Artykuły / Articles}, title={Efficient Phantom Source Widening}, URL={http://www.journals.pan.pl/Content/101499/PDF/04-paper.pdf}, doi={10.2478/aoa-2013-0004}, keywords={source widening, phantom source, decorrelation, IACC}, }
