I am happy to finally release my cross-platform Ambisonic processors useable as VST/LV2 plug-ins or standalone application under Windows, Mac OSX and Linux. They can be used in flexible hosts like Reaper, Ardour MaxMSP or as standalone applications with Jack.
The plug-ins can be used to produce 3D Ambisonic content or do post production on recordings. (eg. Soundfield or Eigenmike microphone recordings)
The Ambisonic order is variable and can be choosen at compile time. A practical limitation for Reaper is 7th order due to the 64 channel limit. The processors use the ambiX convention (full 3D, ACN channel ordering, SN3D normalization)
UPDATE: Sorry I had to temporary remove the download to this software due to license issues. I hope to get it online again soon.

A slightly outdated paper about the plug-ins can be found here: http://lac.linuxaudio.org/2013/papers/51.pdf
mcfx is a suite of multichannel VST plug-ins for MacOS, Windows and Linux
(mcfx_delay, mcfx_filter, mcfx_gain_delay, mcfx_meter)
these plug-ins are very handy if you want to process multiple channels in one go for example
* multiple loudspeaker setups, Ambisonics (see ambiX)
* Microphone array post productions (eg. Eigenmike)
currently high channel counts per track are only possible with the DAWs Reaper (Win, OSX) and Ardour (Linux, OSX)
- channel count is configurable with compile time flag
- cross plattform VST for MacOSX, Windows and Linux
- uses the JUCE framework (www.juce.com)
- ready to use binaries for MacOSX (≥ 10.6, 32/64 bit) and Windows (32/64 bit)
Source code: https://github.com/kronihias/mcfx
Binaries: (4, 8, 16, 24, 32, 36, 64 channel version)
I built version 0.3.10 of QJackCtl for Mac OS X ≥ 10.6.
Get the .app file here:
QjackCtl is a very powerful tool for managing your audio connections within Jack.
Requires: Jack OS X
JACK Meterbridge by Steve Harris is a versatile multichannel Jack metering client. Many different styles of meters with arbitrary channel count may be displayed.
I built and made an installer for MacOSX ≥ 10.6.
A very crucial and maybe often underestimated point for working with (volume) faders, especially in live electronics application is their curve/behavior. Which range does it cover? How fast does “it” get “loud”. What is the behavior around the +0 dB mark?
I sampled the midi volume fader behavior from several of the most popular Digital Audio Workstations. The difference is quite obvious as you can see in the graph to the right.
I made a Pure Data abstraction as replacement for the frequently used [fadtorms] or [dbtorms]. In connection with the .txt sample files it can be used to scale your midi fader input.
Get the abstraction including sample files and Matlab plots here:
I 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.
Sourcecode available on Github.
I compiled the real-time frequency analyzing tools jaaa, japa 0.6.0 and Jnoise by Fons for Mac OS X (>= 10.6) as easy-to-install package.
For generating a test signal (white or pink noise) you can use
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.
The Jack Reverb Plug-In with Ambisonics mode zita-rev-1-0.2.1 is available here:
