iHRTF-Spatializer

A audio plugin for Unity based on Native Audio Plugin SDK and SOFA API_CPP that allow user to load HRTF data from public SOFA database and apply it to Unity audio sources

Installation & Usage:

Simply copy the plugin folder to your Unity Project. The list of usable commands can be found in the iHRTF.cs file
