HRTF clarification question

[GiudiceLab]

We are using spatialized audio in our lab and we are trying to understand how the HRTF is implemented. That is, we know that we can set an audio option for 'HRTF_Full' or 'HRTF_Lite', but we are unclear about what is actually happening. Are we only affecting the DirectX settings? Does Vizard do any additional processing?

Specifically, we are trying to understand how or if the virtual room interacts with the audio virtualization functions, and to what extent we can control these properties in Vizard.
