• 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

Install LINUX Libraries (Debian, Ubuntu):

sudo apt install libasound2-dev libjack-jackd2-dev \
    ladspa-sdk \
    libcurl4-openssl-dev  \
    libfreetype6-dev \
    libx11-dev libxcomposite-dev libxcursor-dev libxcursor-dev libxext-dev libxinerama-dev libxrandr-dev libxrender-dev \
    libwebkit2gtk-4.0-dev \
    libglu1-mesa-dev mesa-common-dev \
	libfftw3-dev \
	libzita-convolver3 \
	libzita-convolver-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) supports loading .wav files directly (optionally reading input channel metadata) just drag/drop a .conf or .wav file into the GUI to load it have a look at CONVOLVER_CONFIG_HOWTO.txt for details about the configuration files check the MATLAB folder for simple export scripts 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)

multichannel level meter with RMS, peak and peak hold

• 0.6.1 (2023-12-08) - mcfx_convolver: support loading .wav files (a .conf file will be written to disk and loaded in the background!), support drag/drop .wav or .conf files onto the GUI for loading

• 0.6.0 (2023-04-16) - new builds optimized for Apple Silicon and 64 bit Intel Mac; Win 64 bit; Update to JUCE 7; removed soxr dependency to simplify build; mcfx_gain_delay: allow sine generator to start at f=10 Hz

• 0.5.11 (2020-05-20) - mcfx_convolver - Mac OS version added a +6dB gain to the filtered output, this is fixed now (Windows version was correct) -> this might influence old projects under OSX since mcfx_convolver will output 6dB less than older versions!

• 0.5.10 (2020-05-19) - mcfx_filter - High-Shelf Q was not stored in the plugin state, this is fixed now

• 0.5.9 (2020-02-05) - mcfx_convolver - fix dropouts/artifacts for hosts that send incomplete block sizes (eg. Adobe, Steinberg), fix reloading of stored presets, add filter length and latency debug messages, fix gui crash in Adobe hosts

• 0.5.8 (2020-01-31) - mcfx_convolver - option to store preset within the project -> allows to exchange a DAW (eg. Reaper) project without need to provide the preset files extra, allow to export stored preset as .zip file for recovering it from the project

• 0.5.7 (2019-04-28) - mcfx_convolver - osc receive support: /reload, /load <preset.conf> -> allows remote control of reloading/loading presets, port can be set in GUI

• 0.5.6 (2019-03-20) - mcfx_convolver - maintain fir filter gain if resampled, add plugin parameter to trigger reload of configuration

• 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

• 0.5.4 (2017-05-20) - mcfx_convolver and mcfx_filter: fixed threadsafety to avoid startup crash if other plugins use fftw

• 0.5.3 (2017-05-02) - mcfx_delay and mcfx_gain_delay fixed glitch in delayline

• 0.5.2 (2017-03-20) - various bugfixes; mcfx_convolver: performance optimizations, adjustable maximum partition size

• 0.5.1 (2016-04-25) - mcfx_convolver: fixed bug in loading packed (dense) matrix; mcfx_gain_delay gui fix

• 0.5.0 (2016-04-08) - add signal generator to mcfx_gain_delay; convolver: support for packed wav file to load a dense FIR matrix from only one .wav file -> have a look at CONVOLVER_CONFIG_HOWTO.txt; filter: smooth iir filter to avoid clicks when parameters change

• 0.4.2 (2016-02-19) - fixed one more convolver bug

• 0.4.1 (2016-02-17) - fixed convolver bug which resulted in mixed up partitions

• 0.4.0 (2015-11-04) - gui for mcfx_delay, gui for mcfx_filter (with fft analyzer), added phase, solo and mute buttons to mcfx_gain_delay

• 0.3.3 (2015-07-19) - performance improvements for mcfx_convolver _

• 0.3.2 (2014-12-28) - audiomulch compatibility, gui for mcfx_gain_delay with paste from clipboard functionality, mcfx_meter added scale offset

• 0.3.1 (2014-06-16) - fixed vst id for bidule compatibility

• 0.3 (2014-03-15) - added mcfx_convolver

• 0.2 (2014-02-25) - removed some license incompatible code, juce update

• 0.1 (2014-01-10) - first release
