Abstract

The invention provides a sound signal processing method, and a terminal. The processing method comprises the steps of acquiring a three-dimensional head model of a terminal user; calculating a first HRTF referring to the fact that a sound wave emitted by a sound source is transmitted to a left ear of the three-dimensional head model and a second HRTF referring to the fact that the sound wave emitted by the sound source is transmitted to a right ear of the three-dimensional head model; and processing a sound signal emitted by the sound source according to the first HRTF and the second HRTF. Inthe prior art, the virtual auditory technology has the disadvantage of virtual audio space synthesis distortion due to depersonalized HRTF. The method solves the problem in the prior art, and improvesthe sound experience of the user.

Description

technical field [0001] The invention relates to audio processing technology, in particular to a sound signal processing method and a terminal. Background technique [0002] The development of virtual reality technology is becoming more and more mature, but the core of virtual reality technology is currently focused on vision. However, when human beings perceive the objective world, they can obtain about 60% of information through vision, about 30% through hearing, and the remaining 10% through senses such as touch and smell. Therefore, in virtual reality technology, virtual Hearing technology is also an indispensable technology. People's perception and judgment of hearing information such as orientation and distance are equally important for people's real virtual reality experience. [0003] Virtual hearing is through the audio signal processing technology, based on some special acoustic effects of the human ear, through the calculation and simulation of acoustic correlatio...
