  • Implementation method of 3D audio
    Publication number: 20030202665
    Abstract: An implementation method of 3D audio, which uses Head-Related Transfer Function (HRTF) to synthesize binaural sound from a monaural source. The implementation method of 3D audio includes the step of establishing a monaural Head-Related Transform Function (HRTF) database and an Interaural Time Delay (ITD) compensation curve by operating a monaural HRTF measurement, which records a set of HRTF coefficients for one ear, so that an externally input monaural signal is converted into a 3D sound signal according to the monaural HRTF database and the ITD compensation curve.
