Virtual sound reproducing method for speaker system, involves sensing listener position with respect to speakers, and generating compensation value by calculating output levels and time delays of speakers based on sensed position

摘要

The method involves generating a two-channel virtual sound from a multi-channel sound, and sensing a listener position with respect to two speakers. A listener position compensation value is generated by calculating output levels and time delays of the two speakers based on the sensed listener position. The output values of the generated two-channel virtual sound are compensated based on the position compensation value. Independent claims are also included for the following: (A) a speaker system comprising a virtual sound signal processing unit and a sound reception position compensation unit (B) a computer readable medium having executable code to reproduce a virtual sound.
