Abstract
Provided are a three-dimensional (3D) sound reproducing method and apparatus. The method includes transmitting sound signals through a head related transfer function (HRTF) corresponding to a first elevation, generating a plurality of sound signals by replicating the filtered sound signals, amplifying or attenuating each of the replicated sound signals based on a gain value corresponding to each of speakers, through which the replicated sound signals will be output, and outputting the amplified or attenuated sound signals through the corresponding speakers.
