Abstract
A three-dimensional audio playing method and playing apparatus are disclosed. The three-dimensional audio playing method according to the present invention comprises: a decoding step of decoding a received audio signal and outputting the decoded audio signal and metadata; a room impulse response (RIR) decoding step of decoding RIR data when the RIR data is included in the received audio signal; a head-related impulse response (HRIR) generation step of generating HRIR data by using user head information when the RIR data is included in the received audio signal; a binaural room impulse response (BRIR) synthesis step of generating BRIR data by synthesizing the decoded RIR data and modeled HRIR data; and a binaural rendering step of outputting a binaural rendered audio signal by applying the generated BRIR data to the decoded audio signal. In addition, the three-dimensional audio playing method and playing apparatus, according to the present invention, support a 3DoF environment and a 6DoF environment. Moreover, the three-dimensional audio playing method and playing apparatus according to the present invention provide parameterized BRIR or RIR data. The three-dimensional audio playing method according to an embodiment of the present invention enables a more stereophonic and realistic three-dimensional audio signal to be provided.
