The purpose of this final project is to implement an FPGA based head related transfer function (HRTF) system. The goal of the HRTF is sound spatialization, where a sound is played in a way such that a person wearing headphones will think the sound is coming from a location in space around their head. In practice the mock spacalization is acheived through filtering the left and right outputs of the music separately, through different FIR filters. These filters are based on filters determined by researchers at UC Davis. Our project utilizes HRTFs in two ways. First, the system allows a user to identify the HRTF which corresponds to their own personal head parameters. While every human has a different HRTF, we can identify a similar enough HRTF such that the user should observe very similar effects to the fully accurate HRTFs. We accomplish this through identifying similar HRTFs and having users test and validate the functions. The second functionality is playing three different sample sounds. Once we've identified a sufficent HRTF, we can emulate spacial sound using convolution and play the sound out fo the audio codec of the FPGA.
