Signal Processing of HRTF

  • Kazuhiro Iida
Chapter

Abstract

In order to analyze HRTFs and apply them to acoustic VR systems, signal processing technique is required. This chapter introduces the methods for calculating the ITD and ILD, and extracting the spectral cues. Furthermore, the methods for convolution of the HRIRs and a sound source signal is introduced.
