HRTF-based spatial audio with Vizard?

[bernie]

Hi there, we'd like to acquire Vizard for our VR labs, and would like to have headphone-based spatial audio including HRTF convolution for individual sound sources.
Is there a way to do that with Vizard?
For examples, some sound card seem to support HRTF rendering - is there a way to use this from within Vizard?
And suggestions/hint/tricks how to do this (and what sound cards might work best) would be highly appreciated!

Thanks,
Bernie
