In this paper, we propose a novel signal processing method called Virtual Ceiling Speaker (VCS) that creates virtually elevated auditory imagery via a 5-channel reproduction system. The proposed method is based on transaural crosstalk cancellation using three channels: center, left-surround, and right-surround. The VCS reproduces a binaurally elevated signal via two surround speakers that inherently reduce transaural crosstalk, while the residual crosstalk component is suppressed by a center channel signal that is optimized for natural perception of elevated sound. Subjective evaluations show that the virtually elevated auditory imagery maintains similar perceptual characteristics when compared to sound produced from an elevated speaker. Moreover, the elevated sound contributes to an enhanced sense of musical expressiveness and spatial presence in music reproduction.
