mcfx - multichannel cross plattform audio plug-in suite

license

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

prerequisites for building

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 libfftw3-dev libsoxr-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:

  • 0.5.11 (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
