-
mcfx is a suite of multichannel vst plug-ins or standalone applications (standalone currently meter and convolver only)
-
channel count is configurable with compile time flag
-
cross plattform VST for MacOSX, Windows and Linux
-
uses the JUCE framework (www.juce.com, GPLv3), libsoxr (LGPL, http://soxr.sourceforge.net)
-
ready to use binaries for MacOSX (> 10.5, 32/64 bit) and Windows (32/64 bit) can be found at http://www.matthiaskronlachner.com/?p=1910
-
these plug-ins have been developed to be used with the ambiX Ambisonic plug-ins: http://www.matthiaskronlachner.com/?p=2015
mcfx is free software and licensed under the GNU General Public License version 3 (GPLv3).
- cmake, working build environment
- libsoxr for the convolver (http://soxr.sourceforge.net)
Install LINUX Libraries (Debian, Ubuntu): $ sudo apt-get install libasound-dev libfreetype6-dev libgl1-mesa-dev libx11-dev libxext-dev libxinerama-dev libxcursor-dev freeglut3-dev libxmu-dev libxi-dev
-
use cmake gui or cmake/ccmake from terminal:
-
NUM_CHANNELS adjusts the number of input/output channels
TERMINAL:
- create a folder in the mcfx folder eg. BUILD
mcfx/BUILD> $ ccmake ..
- adjust NUM_CHANNELS
then mcfx/BUILD> $ make
- find the binaries in the mcfx/BUILD/_bin folder and copy to system VST folder
VST installation folders:
- MacOSX: /Library/Audio/Plug-Ins/VST or ~/Library/Audio/Plug-Ins/VST
- Windows: eg. C:\Programm Files\Steinberg\VstPlugins
- Linux: /usr/lib/lxvst or /usr/local/lib/lxvst
multichannel convolution matrix
loads configuration files (compatible to jconvolver .conf files)
have a look at 'CONVOLVER_CONFIG_HOWTO.txt' for details about the configuration files
searches for configuration file in following folders:
* Windows 7,8: C:\Users\username\AppData\Roaming\mcfx\convolver_presets
* MacOS: ~/Library/mcfx/convolver_presets/
* Linux: ~/mcfx/convolver_presets/
delay each channel about the same time (maximum delay time in seconds is a compile time flag (default 0.5s): MAX_DELAYTIME_S)
filter each channel with the same low/high cut, peak filter and high/low shelf filter settings, frequency analyzer that displays a sum of all channels
low and high pass: 2nd order butterworth filter or 2x 2nd order butterworth cascaded (resulting in linkwitz riley characteristic) for use as x-over network plus 2x parametric filter +- 18dB plus low and high shelf filters +- 18dB
set different delay time and gain setting for each channel (good for multispeaker calibration), includes a signal generator for testing individual channels the GUI allows to paste a list of float gain and delay values from the clipboard with semicolon, comma, newline, tab or space separated. maximum delay time in seconds is a compile time flag (MAX_DELAYTIME_S)
