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.
