For registered users only:
- get two more sets of head-responses for free:
  - the diffuse set: the head responses are manupulated by a small reverb effect
  - the original set: these are the original recorded ony small truncated head responses for best audio results.

- get a program (HRTFconverter) for free to convert the public HRTF sets from the MIT! 
  Convert the data from the MIT (ftp://sound.media.mit.edu/pub/Data/KEMAR) 
  into a valid 3D Audio HRTF file!
  You can manipulate the original data (e.g. with a reverb) and then
  convert the impulse responses into a valid 3D Audio HRTF format!
