mcfx - multichannel cross plattform audio plug-in suite

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

license

mcfx is free software and licensed under the GNU General Public License version 3 (GPLv3).

prerequisites for building

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

howto build yourself:

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

plug-ins explained:

mcfx_convolver

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/

mcfx_delay

delay each channel about the same time (maximum delay time in seconds is a compile time flag (default 0.5s): MAX_DELAYTIME_S)

mcfx_filter

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

mcfx_gain_delay

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)

mcfx_meter

multichannel level meter with RMS, peak and peak hold

changelog:

0.5.5 (2018-03-16) - filter, gain_delay, delay: slider behavior changed for more accurate control; gain_delay: ctrl+click for exclusive solo/phase/mute, add toneburst for signalgenerator, bugfix saving channel state of signalgenerator
