Acoustics for DRY pipe organs

Among the many pipe organs available for Hauptwerk only a few have sampled dry or extra-dry. The possibilities of "reverb" are numerous and not always easy for the end user to focus the acoustic in which to immerse the sound. Among the various possibilities it seems to me that the most used are those based on convolution of IR (Impulse Response). There is also to say that different programs behave differently using the same IR file (for example Altiverb and Pristine Space, the first dark, the second light). Is certain that the quality of IR is the critical element and it is not uncommon to find IR created synthetically.

Premise the following new
Hauptwerk v4.1.0 (scheduled for 2nd half 2010)
• Main focus will be to add support for high-performance convolution within Hauptwerk itself.
and
• Ramsete, Catt, Odeon, Ulyxes, Ease, Raynoise, etc.., Are all programs based on Diverging Beams (cones, pyramids, or the like).
I wonder if the experts can do a little 'light on an area as challenging as fascinating.

To be more explicit, I created a representative example on dry Skinner Our Lady of Mount Carmel:

Might be useful to hear other interesting acoustic ...

Elia,

Good comments and interesting audio comparison. Thank you.

Hi Joe, unfortunately there are few users of dry pipe organs but despite this I will continue the conversation...

A good starting point may be the (inexpensive) commercial IR library http://www.hauptwerk.cz/irs/ designed specifically for the pipe organ. You can try a demo and if you're interested you buy the commercial version of each IR without purchasing the entire library. These are real spaces with few exceptions and with the ability to localize sound in space. Of course you have to take the library as is, with all my respect for the work done.

I have the impression that we can achieve quality results and the results more customizable through a virtual modeling space.

Among the various programs already mentioned above you can try to listen to the following demonstrations:
Auralisations compared to in-situ recordings http://www.odeon.dk/auralisations-compared-situ-recordings
The FIReverb Suite™ audio demonstration http://www.catt.se/suite_music/index.htm
Il seicentesco Teatro degli Intrepidi di Ferrara http://www.ramsete.com/Intrepidi/Intrepidi.HTM
.

What happens to the pipe organ sound?
What happens with the ability to finely localize the organ pipe?
What happens with the ability to model finely space?
