ABSTRACT:
A method and apparatus to reproduce sound using a mono speaker, and a stereo sound system employing the same. The sound reproducing method can include: adding a first channel signal and a second channel signal of an input stereo signal or an input mono signal; sound field filtering by adding a sound field effect to the added signals; convolving the signal of the first channel with a first HRTF in a first convolution process; convolving the signal of the second channel with a second HRTF in a second convolution process; and adding the signal output from the sound field filtering and the signals output from the first and second convolution processes to produce an output signal.
