实现了一个嵌入式三维声音运动系统。基于HRTF（head-related transfer function）的特征提取，设计了一种高效的滤波器系数共享方案，该方案减少了约93%的存储量，并实现了声音在3D空间中所有点的运动。最后，本文还设计了一个基于FPGA的原型系统。
An embedded system for 3D sound movement is implemented. Based on feature extraction of HRTF (head-related transfer function), an efficient scheme for filter coefficient sharing is devised, which reduces the required memory amount by about 93% and enables sound movement at all points in 3D space. An FPGA-based prototype system is also constructed.
