摘要:

采用Prony法在HRTF理论基础上设计了一种应用于虚拟多声道重放滤波器,并利用Verilog进行描述与仿真,开发了一种性能较好的IP核,且在Nexys 3 Spartan-6 FPGA平台上进行了验证。仿真实验结果表明,该款IP核有较高的处理效率,在回放时获得了较好的空间效果特点。

关键词: 虚拟环绕声, HRTF, Verilog HDL, IP核, IIR

Abstract:

This paper uses the Prony method based on the head-related transfer functions (HRTF) theory to design a virtual multi-channel playback filter,and employs Verilog description and simulation to develop a better performance of the IP core,which is validated on the Nexys 3 Spartan-6 FPGA platform.Experimental results show that the IP core has high efficiency and good characteristics of spatial effects during playback.

Key words: virtual surround sound;HRTF;Verilog HDL;IP core;IIR
