The localization of amplitude-panned virtual sources is biased towards the median plane when loudspeakers are not positioned symmetrically with the median plane. The bias is measured using listening tests and with computational modeling of virtual source perception. A modification to an existing pair-wise panning method is proposed that compensates the displacement of virtual sources. The proposed method is evaluated by interpreting conducted listening test results, and by simulating virtual sources with computational modeling. Evaluations suggest that the bias is non-existing with the proposed method.
