Abstract
The present disclosure discloses a method and an apparatus for sound processing in a three-dimensional virtual scene. The method includes: acquiring, by a three-dimensional program engine, a sound processing request of a sound source point in a virtual scene; invoking a corresponding head-response transfer function (HRTF) according to a three-dimensional coordinate position relationship between the sound source point and a sound recipient in the virtual scene; modifying a parameter value of the HRTF according to the virtual scene where the sound source point is located; and performing filtering and delaying processing on a sound signal of the sound source point by using the modified HRTF. In the present disclosure, an HRTF parameter is modified flexibly according to audio effect requirements of a virtual scene, so that the technical problem that sound localization performed by using an HRTF database of existing hardware in some virtual scenes has undesirable effect is solved, thereby achieving the effect of optimizing three-dimensionally located audio effects.
