As addition to the Ambisonics Decoder, Microphone Processor and LADSPA Plug-Ins I compiled and packed the convolution software jconvolver 0.9.2 as easy-to-use installer for Mac OS X >=10.6.
This Jack client is a very flexible real-time convolution engine, including configurations for applying Multichannel Ambisonics reverb.
jconvolver-0.9.2-installer.pkg
You can find some additional Ambisonic reverb impulse responses here:

The Jack Reverb Plug-In with Ambisonics mode zita-rev-1-0.2.1 is available here:

REQUIREMENTS:
JackOSX:
http://www.jackosx.com
jconvolver HOW-TO:
* Start Jack with JackPilot or QJackCtl
* Check this folder for example configurations: /Library/jconvolver/config-files
* Download Impulse Responses from URLs provided in config files and adjust path setting in config files
* Start jconvolver, fconvolver or makemulti from Terminal session with appropriate arguments (eg. jconvolver /Library/jconvoler/config-files/weird.conf )
* Make connections with Jack
INSTALLATION LOCATIONS:
Configuration examples will be installed in /Library/jconvolver/config-files.
The required binary files and libraries will be installed in /usr/local/bin, /usr/local/lib and /usr/local/lib64.
NOTES:
I did a small modification to libzita-convolver Library to NOT make it stop processing if a CPU overload is detected (too much cycles passed).
This is rather rude. There should be a possibility to make realtime work better in OSX.
Many “Computation threads are late” messages may appear. Sometimes clicks may be audible.
This should of course be fixed sometime!
