Youlean Loudness Meter 2

One critical aspect of proper mastering, and also mixing, isbeing able to monitor properly.

Youlean Loudness Meter 2 is a free loudness metering pluginthat features four metering modes; LUFS, LRA, DR and true peak.

It’s one of the most accurate loudness metering plugins outthere, even when compared to other premium ones, and a lot of producers use it…

Which is a clear testament to its overall quality.

Even though you can get it for free, it does have a Proversion which comes with additional features.

This is an essential tool for any producer, especially ifbudget is an issue, since it will help you determine the proper amount ofloudness without sacrificing quality or dynamics.

The great thing is that it’s also a very visual plugin…

You can not only hear, but see what is going on… and this isalways a plus!

Not only this, but it includes loads of presets so you canmake sure to sound great on all the streaming platforms like Spotify, YouTube,etc.

You can download it here.

This is a simple and easy to use plugin which is better thansome of its premium counterparts.

It is a multivariable meter including RMS, EBUR128, VU andPPM measurement.

Additionally, it has multi-channel metering…

This means that you can see what’s happening on the stereo,left, right, mid, or side channels.

You can even choose between five different themes, if youdon’t like the look of a particular one…

SPAN by Voxengo

SPAN is a free spectrum analyzer plugin which is absolutelyessential for mastering if you want your mixes to end up sounding loud but notcrushed.

It has a fairly simple Interface which, in my opinion, doesn’treally look that great… but it’s still customizable to some extent.

However, it’s very accurate and useful, plus it’s compatiblewith almost any DAW available right now.

It comes loaded with features such as being able to routemultiple tracks into SPAN and then comparing their frequency content.

Applications

  • Fast Fourier transform spectrum analyzer
  • Stereo, mid-side, surround spectrum analyzer
  • Stereo correlation meter
  • EBU R128, K-system meter
  • RMS, true peak level and clipping detector

You can download it here.

LoudMax by Thomas Mundt

LoudMax is a Loudness Maximizer Plugin with a clean andtransparent sound.

It is designed to retain the original character of the musicas much as possible even at high compression levels.

It’s a very simple yet powerful tool.

It has two sliders which are: Threshold and output.

LoudMax is a plugin which I’d recommend to beginners sinceits simplicity will better help you understand how to properly use a limiter.

But, even though it’s extremely simple, it’s still a greatplugin!

Features

  • True Peak Limiting (Further information for ISPbelow)
  • Supported Samplerates: 2kHz – 384kHz
  • Latency: 1.25ms (+ 6 samples with ISP)
  • Look-Ahead and Attack Time: 1.25ms
  • Release Time: Automatic – depending on the inputsignal
  • No audible distortion
  • Possible overdrive: 740dB
  • Very low CPU usage

You can download it here.

Limiter №6 by Vladg Sound

Remember I said that LoudMax is a very simple plugin withjust two controls?…

Well, Limiter №6 is far more complex and also versatile…

This is why I wouldn’t recommend it to absolute beginners.

It offers more control than LoudMax, meaning that it allowsyou to do more detailed tweaking, but it’s a bit harder to use.

It has five modules which include: RMS compressor,peak limiter, high-frequency limiter, clipper, true peak limiter.

Even some premium plugins don’t come with such featuresincluded…

So, definitely give it a try!

Features

  • 5 modules: RMS compressor, peak limiter,high-frequency limiter, clipper, true peak limiter
  • high-quality signal processing to use formastering purposes
  • brickwall and soft limiting with differenttiming settings
  • M/S and multiband modes
  • optional 4x oversampling
  • true inter-sample peaks (ISP) limiting
  • analog-style indication
  • 2 different GUIs

Stereo Tool v3 by Flux

It also comes with an accurate visual feedback, reflectingthe content with;

A vector scope, PPM meters for inputs/outputs, phasecorrelation meter permanently monitoring the signal and individual left andright polarity reversal.

In some cases, mixes require some balancing of theinformation between the channels, and if your mix has some balance or phaseissues, then StereoTool can be quite helpful.

Features

  • Input Gain controls for adjusting the level forleft and right channels before processing
  • Phase inversion of the incoming signal on leftand right channels

IVGI by Klanghelm

I love Klanghelm. I use a couple of their compressors andthey all work great!

So, it’s no surprise that this saturation and distortionplugin is also excellent!

Adding a bit of saturation to your final mix can completelychange the way it sounds, and in a good way!

One of the issues in todays music industry is that we allrecord using digital gear, which is fantastic in its own way…

But some of those older sounds that we love came from theimperfections of recording with tape and analog gear.

This is why adding a bit of warmth, using a saturationplugin, can do wonders!

Not only can IVGI add warmth, but it can also be used tocompletely distort tracks, and it also lets you alter the frequency dependencyof the saturation with the RESPONSE control.

You can download it here.

Ferric TDS By Variety of Sounds

Ferric is a tape dynamic simulator which was inspired by thedynamic shaping capabilities of some high-end reel-to-reel tape recorders.

It simulates three of the most distinctive sonic effects ofthese devices:

  • Dynamics: gently shaping the overalldynamic response.
  • Saturation: adding extra harmonic-relatedcontent.
  • Limiting: controlling peak performance.

Since most people don’t have access to vintage tapemachines, they would need some sort of plugin to achieve the same effect…

And this is where Ferric TDS comes in!

It simulates dynamics for shaping the overall dynamicresponse, adds extra harmonics and saturation effects, and controls outgoingpeaks.

You can download it here.

Looking for free Distortion VSTs? Here’s a post I wrote about the best ones.

A1Stereo Control by Alex Hilton

Often times you’d want to give your mixes a wider andexpansive sound…

This is where A1Stereo Control comes in.

One issue can arise which is “widening the bass end”, sincethe bass should always be in the center.

This plugin comes with the “Safe Bass” algorithm whichcenters everything below a user-configurable value.

This gives your tracks the solidity and definition you want whilepreserving maximum transparency and sharpness.

Simply turn on “Safe Bass” and adjust thefrequency if needed and that’s it… It’s really that simple.

You can download it here.

Baxter EQ by Variety of Sounds

Like I mentioned earlier, EQ is an absolutely critical elementof the mastering process…

And it is used for very gentle accentuation of specificfrequencies which affect the whole mix.

BaxterEQ was designed to be used for this specific purposewhich is why is has a full dual channel layout as well as mid/side encodingsupport, and per-channel level for easy A/B matching.

Features

  • lowripple and distortion filter implementations
  • 64bitfloating point internal processing
  • oversampledfor superior impulse response
  • naturaland accurate bass response
  • authenticanalog style HF curve rendering
  • smoothestshelving operation

You can download it here.

ClipShifter 2 by LVC Audio

ClipShifter is a wave-shaping audio plugin that functionslike a clipping-style limiter.

It provides enough user controls to be useful in all mixingstages: from distorting basses and drums, to maximizing mix buses andwarming-up overall mixes.

The distortion can be altered from a hard, brickwall-styleclipping, to softer saturation with compression.

ClipShifter can be used in static or dynamic mode.

Also, there is an independent left/right or mid/sidecontrol.

Most of the features of this plugin are free, but if youwant to access all of them, you’ll need to purchase the premium one…

Or you can purchase Clipped-Max which is an updated version of the software, plus it includes a key for ClipShifter as well.

Features

  • Clipping style limiter
  • Controls for Clip Shape (hard to soft) andharmonics
  • Low CPU usage
  • Standard LVC-Audio metering, including VU-style,PPM-style, and loudness meters to easily monitor input and output levels
  • Scalable waveform history view

You can download it here.

Looking for free Drum VST plugins? Here are the best ones.

Bitter Sweet V3 by Flux

Flux is a well-known and respected company that createdhigh-quality plugins…

Bitter Sweet is basically their free version of a sweeteningplugin.

At its core, this is a tone and transient shaper pluginwhich with just one turn of a knob can reduce/magnify the transients, makingthe sound sweet or bitter.

By turning the knob to the sweet side, you get a very smoottransient which brings a silky tonal character with it.

On the other hand, turning it to Bitter, you get a much moreaccentuated and aggressive tonal characteristic.

Since this plugin is so easy to use, I’d say that evensomeone who is a complete beginner should download it!

Features

  • Upto 8 channels Input/Output
  • OutputGain
  • Controlsthe Output Gain at the end of the processing (-/+ 12 dB).
  • Linkto Output Gain – Compensates the Output Gain depending on the Transient Amountin order to achieve unity gain.

You can download it here.

Stereo Buss by Minimal System Group

Mastering

This is a free compression plugin specifically designed specifically for Master Bus compression.

Compression helps glue all the tracks together to createthat sense of congruency in the mix, and while this is certainly doable withmost compression plugins…

Stereo Buss does it better!

Basically, if you’re looking to add some finishing touches toyour mixes, then Stereo Buss might be the compression plugin you need!

Tip: Try introducing the Stereo Buss Compressor earlyin the mixing process.

This all depends on how you like to mix, but it often timeshelps with gluing the tracks together faster…

And this means faster mixes!

Features

  • AnalogueModelled Buss Compressor.
  • TheXStudioToolz stereo Buss Compressor can be used on the Master Buss and also onsub-groups (Drum Groups etc).
  • Greatvisual feedback.
  • Greatsound.
  • Presets.
  • ProfessionalGUI Design.
  • Verylow CPU usage.

You can download it here.

Wider by Polyverse Music

This is a simple free plugin that widens your stereo signal…

The added benefit of Wider is that it does this withoutcausing phase issues when you listen to the mix in mono because any widenedsignal will always remain in phase.

It’s extremely easy to use because you can only control oneparameter; the width.

And that’s it!

It creates a much wider stereo feel and it doesn’t mess withthe phase at all!

Excellent plugin that I absolutely recommend!

You can download it here.

Conclusion

I hope I was able to provide the information you neededhere.

I believe that all of the plugins on this list areabsolutely amazing considering that they are free!

Wider is fantastic, and I also love Youlean Loudness Meterand mvMeter 2.

Give them a try and see how you like them!

Have a great day!

  • Best Auto-Tune VST Plugins; Free and Paid! - July 7, 2020

This post is for the Mac users.
When it comes to Mac OS X, the number of freeware plugins is very low, compared to the Windows world.
The popular “Save as VST” softwares (Synthedit and Synthmaker) are Windows only.
The “upgrade” politic of Apple is a sort of nightmare for developers (and sometimes users!), so many old free plugins don’t work anymore…

I have searched for free MAC plugins over the web and then tested !
– only free synth (not effects), in VST and or AudioUnit (AU) format
– the OS used is Mac OS X 10.8 (Mountain Lion)
– i tested the plugins in Ableton Live 9 / Renoise / some free VST & AudioUnit host softwares (Pedalboard, the JUCE open source plugin host, VSTLord, AULab, Ugly VSTi Interface…)

It’s a selection with free virtual analog synths, organ emulations, epiano emulations, drum synth, bass synth, FM synth, emulation of Oberheim / NordLead / DX 7 synth, chip synth, guitar emulation…

and here a list of 25 free synth plugins for Mac OS X :

1. Synth1 AU/ VST

The must-have free synth plugin is available for Mac since one or two years, it is in beta state, it still have some minor bugs with the UI, but it’s usable and you can benefit from the incredible amount of presets created for Synth1, including these 😀

U-He loves the Mac, don’t hesitate to have a look at the other freeware on the Website, all are working without problems in VST or AudioUnit format. I have also selected Triple Cheeze and Zebralette from the same developer. These plugins are good and full featured.

TyrellN6 plugin comes with a big amount of presets, and a deep variety of sounds. It’s powerful and easy to program. It’s rock solid stable and have a nice UI too!

6. TAL NoiseMaker AU / VST

TAL Noisemaker

Like U-He, TAL has many freebees for Mac OS X.
I have selected Noize M4k3r and Elek7tro but you also have other interesting plugins.
The “Noise Maker” plugin has two osc + sub, a good filter and the famous Chorus “a la Roland”, so you have all you need for your fat bass/lead. Certainly more agressive than Crystal, it completes well the sonic arsenal.

7. Dexed FM VST

The famous free Yamaha DX7 emulation ! It’s VST only (no AU for the moment).
Use the cart / load / save button to browse or import presets.
It can read / write sysex files for and from the DX7.

8. MiniSpillage AU (Drum Synth)

MiniSpillage AU

Now that we have the FM synth, the Pad synth, the Bass synth and Lead capable synths, we need a DRUM synth. The Minispillage plugin has three dedicated algo for bass drum, wood drum and hihat.
I tend to prefer “Drumatic” but Drumatic is Windows only.

After all these synths, we now need an emulation of our prefered organ : the Farfisa combo organ!
ComboF gives you the sound of the Italian electric organ we all love. Available for Mac and windows, in AudioUnit and VST!

MrTramp2

After the organ emulation, we need the electric piano! MrTramp 2 is the best (free or not) emulation of the Wurlitzer electric piano. It’s raining again ! Now you can sound like Supertramp ! Breakfast in America !! There are not so much controls but you don’t need more, and the sound is excellent.

11. Cheeze Machine AU

A dedicated string synth plugin for Mac ! The Cheeze machine from Big Tick is a kind of Arp Solina emulation. It has this phaser / chorus creamy sound.
it’s AU only and should work with your favorite Mac host software.

TripleCheeze plugin

Cheese again !
The U-He contribution to the first KVR Developer Challenge. It’s an original synth with unusual sound generation. Nice for plucked sounds. Works well on my Mac OS X Mountain Lion. Thanks to the comb filter, you can generate very original sounds.

VB1 bass

Another prehistoric virtual synth from Steinberg, this virtual bass plugin is free and available with Model E in the same package (see link above). Very simple sound, can be useful.

19. MDA Piano ePiano DX10 & JX10 VST

NO GUI

These free VST work for Mac OS X, they don’t have UI, you’ll have to use the default interface supplied by your host.
– Piano & ePiano are sample based synth, the ePiano is very good, it’s a kind of Rhodes emulation.
– DX10 is a FM Synth, it has only two operators, but you can still get nice bell sounds out of it.
