Hi everyone!
   I wonder: Is spat3d in mode 4 (a pair of micorphones) really the best thing 
csound can do when it comes to simulate an audio signal in a 3-dimensional 
room?
   Sometimes I feel, that the effect is very subtle, although I set extrem 
parameters (25m below, from 70m back to 2m behind the listener).
   Which parameters of the necessary ftable can help me to intensify the 
effect?
   Kindest regards
              Julien

No, I think the new hrtf opcodes are the better.

Hi Victor!
   But, correct me if I'm wrong, with HRTF you can't simulate rooms and change 
distances. You can "only" move a signal on a surface of a ball (roughly). What 
I like is changing room-accoustics, putting something far from the listener, 
moving it towards him. Or in general not moving my sound-input in a circle but 
in a flat line somewhere.
   Or are there new features with the new opcodes?
   Kindest regards
          Julien

I suppose you are right in one sense, but if you add the other cues 
(reverb, lowpass filtering,
intensity changes), then you would have the full effect. The thing is that 
spat3d adds
these things, but does not have the quality/precision of hrtf.

Also, you might want to try babo. With it you can even do doppler (as a 
side-effect).

Hello Victor!
   Which reverberation opcode should I use in connection with thehrtf-opcodes 
to get the desired effects?
   Kindest regards
          Julien

Try first babo, without hrtf. Then see if adding hrtf enhances the effect.

Otherwise, I would use freeverb.

Hi,
I am currently looking into the possibility of headphone HRTF based reverb
using the algorithms in the new HRTF opcodes as a starting point...
Hopefully such a tool could provide all of the mentioned aspects of source
distance, spatialisation and environmental processing...(although processing
cost may be high!)
