Method and apparatus for expanding listening sweet spot

摘要

A method and apparatus of expanding a listening sweet spot. A method of expanding a listening sweet spot with respect to signals output from speakers includes: obtaining an HRTF (head related transfer function) at a position of a listener's ear; moving a first virtual ear around the position of the listener's ear; obtaining an HRTF at each position of the first virtual ear; and processing a signal to be input to the speakers using the obtained HRTFs to output to the speakers.
