DarwiinRemoteOSC Mountain Lion

darwiinremote-oscI fixed the program DarwiinRemote for Mac OS 10.8 (Mountain Lion) and added Open Sound Control (OSC) support for the most recent version. Download it here:


DarwiinRemoteOSC allows to connect via Bluetooth to the WiiRemote controller. It also supports Nunchuk, Classic Controller and Balance Board.
All data from the Wii Controller is forwarded via OSC. IP and Port can be changed by command line argument. OSC can be sent to DarwiinRemoteOSC to turn on Force Feedback, LEDs and retrieve Battery status.

jconvolver 0.9.2 and zita-rev-0.2.1 for Mac OS X

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.


You can find some additional Ambisonic reverb impulse responses here:

ambdec-0.5.1, tetraproc-0.8.2, AMB-plugins-0.8.1 for Mac OS X

(C) Fons AdriaensenI compiled the latest versions of Fons Adriaensens’ Ambisonics Decoder ambdec-0.5.1 (PDF manual) and his Microphone-Processor to convert TetraMic recordings to B-Format tetraproc-0.8.2 (PDF paper) for Mac OS X.

I packed them in easy-to-use installer packages which should run under Mac OS X >=10.6 (Snow Leopard, Lion, Mountain Lion):

Note about ambdec: The manual is outdated! The configuration window is gone. Use a Texteditor to edit .ambdec files!

ambdec-0.5.1-installer.pkg(C) Fons Adriaensen

Make sure you have JackOSX (http://www.jackosx.com) and X11 (http://xquartz.macosforge.org) installed.

Troubleshooting: Sometimes the installer does not set the file permissions for graphic files correct, try to check if the folder /usr/local/share/ambdec is read/writeable for the user. You can start ambdec from Terminal and check for error messages (just type ambdec in Terminal and hit Return).

Additionally I compiled and packed the LADSPA Ambisonics Plug-In Set (AMB-plugins-0.8.1) for 32/64 bit on Mac running in Ardour under Mac OS XOS X >= 10.6 to use within Ardour.
