摘要：
A method of reproducing a virtual sound and an apparatus to reproduce a 2-channel virtual sound from a 5.1 channel (or 7.1 channel or more) sound using a two-channel speaker system. The method includes: generating a 2-channel virtual sound from a multi-channel sound, sensing a listener position with respect to two speakers, generating a listener position compensation value by calculating output levels and time delays of the two speakers with respect to the sensed listener position, and compensating output values of the generated 2-channel virtual sound based on the listener position compensation value.
