MFreeFXBundle is a free bundle of effects distributed by MeldaProduction, a developer based in the Czech Republic. The official site calls it “the biggest and most powerful free plug-in pack”, and it holds 38 effects in all, including EQ, compressor, reverb, delay and various analyzers (tools that measure sound and display it). This page covers how to get it, what is included, how it differs from the paid version and where it fits.
Disclosure: this site uses affiliate programs. Whether the plug-in is free, and its features and supported formats, were checked on the maker’s official pages around 2026-10-16. Terms of distribution can change, so please check the official page before you download.

What is MFreeFXBundle?
The official site describes MFreeFXBundle as “a completely free set of audio effects”. The paid plug-ins from the same maker have more features, but the official explanation is that the free versions are also better than typical plug-ins. It is also explained that you can buy a paid licence at any time to extend the features.
In the official categories, the 38 effects are split into analyzers, saturation and distortion, mixing, filters, reverb, stereo, pitch and more. Most have names that start with M, such as MEqualizer and MDelay, and many make their role clear from the name.
Main effects included in MFreeFXBundle
- MEqualizer (per the manufacturer): A 6-band EQ with an analyzer.
- MCompressor (per the manufacturer): Described as a compressor whose processing shape (curve) you can change freely.
- MDelay (per the manufacturer): The official site calls it “the most powerful free delay”.
- MCharmVerb and MConvolutionEZ (per the manufacturer): MCharmVerb is an algorithmic reverb based on the engine of the company’s MTurboReverb. MConvolutionEZ is a convolution reverb (a reverb that uses recordings of real spaces) optimised to be easy to use.
- MSaturator, MWaveFolder, MBitFun, MWaveShaper, MFreqShifter and MRingModulator (per the manufacturer): Six saturation and distortion tools, from smooth, tube-like saturation to extreme distortion.
- MAutoPitch and MTuner (per the manufacturer): MAutoPitch is automatic vocal tuning, and MTuner is an instrument tuner.
- MAnalyzer, MLoudnessAnalyzer, MStereoScope and MOscilloscope (per the manufacturer): Seven analysis tools, including a spectrum analyzer, a loudness meter, a tool for viewing stereo width and an oscilloscope.
- MStereoExpander, MSpectralPan, MUtility, MRecorder and more (per the manufacturer): Also included are stereo correction, panning by frequency, level adjustment and a tool that records the input to WAV.
Features shared by all the plug-ins
The official features page lists the following shared features (per the manufacturer).
- Automatic gain compensation and a safety limiter: They have a compensation that makes the level less likely to change when you change settings, and a limiter that keeps the output at or below 0 dB.
- A to H switching and A to D morphing: You can save several settings and compare them, or blend smoothly between four settings with an XY pad.
- Control from MIDI controllers: With the MIDI learn function you can move parameters from a piece of gear at hand.
- Randomize functions: Three ways are listed: randomize everything, change things slightly, and use “smart” changes.
- Preset sharing: It is explained that presets can be exchanged with the company’s server.
- How licensing is handled: The official site says no USB dongle or internet connection is needed for licence activation, and that a licence file is used.
The official features page also explains modulators (a mechanism that moves parameters with things like LFOs), but some of these functions are not available in the free version. See “What changes with the paid version?” below.
What changes with the paid version?
The official site explains that you can keep using it free, but that upgrading lets you do the following.
- Change the size and visual style of the plug-in window
- Use the sonogram (a display of how frequencies change over time) in the analyzers and equalizers
- Save, load and organise your own presets
- Use modulators
- Use upsampling to reduce aliasing (fold-back noise) and raise the sound quality (in many of the plug-ins)
- Remove the large red notice box at the bottom of the window
In other words, the free version has limits such as window size and saving presets. One order to consider is to check how it feels in the free version first, and look at the paid version if you need it. For the price of the paid version, please check the official page.
Who MFreeFXBundle is for
- People who want to get basic effects such as EQ, compressor, reverb and delay together from one maker
- People who want to check the state of a mix with free analyzers and a loudness meter
- People who want to try a variety of unusual saturation and distortion tools
- People who want to leave room to expand the features later with the paid version
With as many as 38 effects, you may at first be unsure what to use. Starting with just four, EQ, compressor, reverb and delay, seems easier to sort out.
Tips for using MFreeFXBundle
- Start with MEqualizer and try the basics, such as cutting unneeded low end or tidying a muddy sound. It has an analyzer, so you can adjust while seeing which bands have more energy.
- With MCompressor, moving the settings a little at a time while watching the gain reduction (how much the level is pulled down) may make its effect easier to understand.
- When you change a setting, a difference in level can make you feel it “sounds better”. These plug-ins have automatic gain compensation, which should help when you compare.
- MLoudnessAnalyzer may be useful for checking level before you export. For each streaming service’s standard, check that service’s official information.
- For detailed instructions, the manual and tutorial pages on the official site are useful.
