Abstract: A virtual sound image localization method in a two-dimensional (2D) space and three-dimensional (3D) space is provided. The virtual sound image localization method may include setting a reproduction region including at least one loudspeaker available in an output channel; dividing the reproduction region into a plurality of sub-regions; determining a sub-region in which a virtual sound source to be reproduced is located among the sub-regions; determining a panning coefficient used to reproduce the virtual sound source, based on the determined sub-region; and rendering an input signal based on the panning coefficient.
