Audio Spatialisation

  • Developed a binaural audio spatialiser using Head-Related Transfer Functions to create spatialisation effects in AR
  • This is prototyped as a C/C++ native module for ARM64 UWP platforms
  • The source code is available here: DSP tools

  • The spatialiser was tested by running a subjective study, where participants would test spatialisation effects
  • The test produced some interesting results on the use of custom HRTFs and ray tracing in AR devices
