ABSTRACT:
A stereo sound generation method and apparatus to generate a stereo sound, by using 2-channel headphones, earphones, or speakers, from a multi-channel sound signal reproduced through a variety of media such as a DVD-video, and a DVD-audio. The stereo sound generation method of generating a 2-channel stereo sound from a 5.1-channel sound signal includes: generating a first channel stereo signal and a second channel stereo signal, by applying the difference between times taken to arrive at two ears of a listener, respectively, and a difference between sound pressures of the two ears that are different or constant in frequency to each of a first channel signal and a second channel signal being input; generating a first channel stereo signal and a second channel stereo signal, by applying the difference between times taken to arrive at the two ears, respectively, and the difference between the sound pressures of the two ears that are different or constant in frequency, to each of a third channel signal and a fourth channel signal being input; generating a first channel signal and a second channel signal from each of a fifth channel signal and a sixth channel signal being input; generating a plurality of reflected sounds, by applying delay values and gain values different from each other to first through fifth channel signals being input, and from the plurality of generated reflected sounds, generating a first channel signal and a second channel signal; and adding the generated first channel signals and adding the generated second channel signals.
