multichannel cross plattform audio plug-in suite

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).

Please note that Steinbergs VST SDK is not free in the sense of the Free Software Foundation, but is the de facto standard for creating audio plug-ins. Don't use the VST version of this software if you are not comfortable with mixing free and non-free code.

prerequisites for building

• cmake, working build environment
• libsoxr for the convolver (http://soxr.sourceforge.net)
• Steinberg VST 2.4 SDK

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:

copy the Steinberg VST 2.4 SDK into the folder mcfx/vstsdk2.4 (do to legal reasons those can not be included here)

• 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) 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

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) 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
