We had minimal success using 'hrtfer., We are running csound on an SGI
Indy 2 running IRIX5.3. It was not posible to run it in 'real-time.'
What came out was a vague notion of the real sound. When not in realtime
the sound was fine but we could only get the sound to go behind us(using
headphones).
I used SOUNDHACK HRTF a few years ago and it seemed to work okay,
although I don't remember if that was in real-time or not. Again it only
works well when wearing headphones.
I hope I helped, John Beahan
