Abstract

Examples of the present invention provide a head -related pulse shock data set processing method.The method of the present invention includes: the processor puts the head -related pulse stroke HRIR dataset in accordance with the elevation angle and / or horizontal angle;Gaowen HRIR sample points; the processor reduces the dimension of the HRIR sample point to a low -dimensional space to obtain a low -dimensional HRIR;Sample points; the processor combines the characteristic HRIR sample point into a three -dimensional matrix in the three -dimensional matrix in accordance with the elevation angle sequence and / or horizontal angle order.Examples of the present invention solve the problem of excessive errors in the feature HRIR selection method.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer science, and in particular to a method for processing head-related impulse response datasets. Background technique [0002] Human hearing can not only perceive the pitch, intensity, and color of sound, but also distinguish the direction and distance of the sound source. In order to enable the audience who are not present to obtain a realistic "sense of presence", people have invented three-dimensional audio technology. Three-dimensional audio technology can truly reproduce the sound information of the original sound field, so that the listener can have an "immersive" listening experience. Three-dimensional audio can be realized through "binaural sound" technology, that is, head-related transfer function (Head Related Transfer function, hereinafter referred to as: HRTF) is used to filter the single-channel sound source signal, and the obtained sound with a sense of direction is then u...
