Hi Iain,
there is a collection of Csound instruments I wrote which does
everything that you need, though it is still a bit hard to operate:
- spatialisation up to 3rd order ambisonic
- distance clues
- specular early reflections
- diffuse early reflections
- local reverb
- spatial global reverb (12 decorrelated reverberations distributed in
space by 2nd order ambisonic )
It sure is possible to exchange the generator of the reverb with IR-
convolution in that code. There is an update on my code, which I will
release tomorrow at my pages otherwise feel free to contact me off
list and I will send you the .csd.
All the best,
Jan Jacob

Hello list,
I would like to know what jack compatible systems are available on
Linux
to spatialise a moving mono source in realtime with ambisonics
(including distance attenuation) that also provide some reverberation
cues.
I've tried spat3d in csound with a GUI - and while this spatialises
the
source very well, I've not been so happy with the sound of simulated
room reflections - perhaps it's the way I am setting it up. I'm also
looking at the SoundScape Renderer (SSR) which is very nice - but
doesn't seem to have an implementation of reverberation for moving
sources.
Is convolution reverb a possibility for a moving source - eg. is it
possible to cross-fade between the inputs of ambisonic IRs set up in
jconvolver recorded at various angular locations? This would be ideal
for my application which involves the spatialisation of an actress'
voice within a room - so that she appears to be walking (and talking)
through the space in relation to a seated listener.
Cheers,
Iain
