Head Shadowing Filter for 3D audio with headphones

Abstract

There are several methods to achieve 3D sound in the headphone listening environment now.However, for virtual sound sources, engineers want simply create the localization information by digital process. Through making appropriate time delays and spectral characteristics, there are different methods to simulate natural spatial cues now. In this report we will show a solution of using the Matlab functions to create filters which can simulate those cues.
