1. Youlean Loudness Meter

by: Youlean

Youlean Loudness Meter

Youlean Loudness Meter Free Version has everything you need to measure the true perceived loudness of your audio. Tested and calibrated, this plugin guarantees the great accuracy of the measurements. Loudness graphs come with the ability to go through history and this will help you to pinpoint the problems in your measurements. You will achieve a better mixdown with more control and the better understanding of the loudness.

You can use it on mono, stereo or 5.1 audio content.  It comes with a mini view, resizing and scaling GUI which makes it suitable for every screen you work on, high DPI or not.

Easy to use, no spam, just free.

2. 2BusControl

by: MAAT


Free comprehensive stereo master monitoring & metering plug-in!

A free universal L/R plus MONO/DIFF monitor control and Balance/Correlation metering plug-in for stereo bus masters.


Available for all major plug-in formats, including VST/VST3 and AAX for macOS and Windows plus Audio Units for Mac OS, 2BusControl offers five essential options for specialized monitoring modes plus highly responsive and user- friendly metering for left/right balance and correlation. Solo is available post-metering with a single button push. Traditional left/right soloing (as phantom centre) can be chosen, or the equally useful MONO/DIFF(erence) or M/S (Mid/Side) rendering of the soloed signal. In addition, the stereo perspective can be swapped or flipped with the left and right channels changing places. Each solo control is a single button, allowing you to check placement and amplitude easily for all aspects of your mix.

Usable metering is another essential for any engineer, and options are equally practical, with stereo balance and inter-channel correlation occupying the upper half of the user interface. Unlike prior products that provide similar metering functions, 2BusControl´s measurement and display algorithms adhere to our guiding philosophy of enhancing your workflow and improving ergonomics through careful attention to the way you actually work. Ballistics are meticulously tuned to achieve the best match between the aural impression you hear, and the optical rendering by the meters.

All of 2BusControl´s functionality is wrapped in an information-rich yet visually unobtrusive user interface that occupies only a small slice of screen real estate. Likewise, the plug-in is “lightweight” demanding a minimum of CPU resources so it won´t slow down your host. As an introduction to everyone in the audio community, we’re giving you this free and rather useful plug-in. Thanks for visiting, and we hope to be working with you more in the future!

  • Essential – 2BusControl delivers indispensable monitoring controls, plus visually expressive metering.
  • Light Weight – 2BusControl is economical of both screen real estate and host computer resources.

3. Voxengo Correlometer

by: Voxengo

Voxengo Correlometer

Correlometer is a free analogue-style stereo multi-band correlation meter AudioUnit, AAX and VST plugin for professional sound and music production applications. It is based on a correlation meter found in the PHA-979 phase-alignment plugin.

The multi-band correlation meter is an advanced way to check for the presence of out-of-phase elements in the mix. Broadband correlation metering reports overall phase issues and may misrepresent problems present in select spectral bands, while multi-band correlation meter easily highlights problems present in mid to high frequencies that are not easily heard by the ear, but may still reduce the clarity of the mix.  Another application of multi-band correlation metering is phase-and time-aligning of channels and tracks, especially bass and bass-drum pairs, guitar mic and D.I. source pairs, two-microphone stereo recordings, etc.

Correlometer can display 4 to 64 individual spectral bands, with an adjustable band quality factor that controls the degree of the band’s selectivity. Averaging time of correlation estimator can be adjusted. Correlometer supports side-chain inputs for easy correlation estimation between separate audio tracks.


  • Multi-band correlation metering
  • Phase issues detector
  • Cross-track phase coherency estimation
  • Mono-compatibility checker


  • 4 to 64 band correlation meter
  • Adjustable band quality factor
  • Adjustable averaging time
  • Side-chain input
  • Resizable user interface
  • All sample rates support

System Requirements

  • This audio plugin can be loaded into any audio host application that conforms to the AudioUnit or VST plugin specification. Plugins with AAX version available can be loaded in ProTools 12+.
  • This plugin is compatible with Windows (32- and 64-bit Windows XP, Vista, 7, 8, 10 and later versions) and macOS (10.11 and later versions, 64-bit Intel processor-based) computers (2.5 GHz dual-core or faster processor with at least 4 GB of system RAM, SSE4.2 instructions support required, e.g. any Intel Core i-, AMD Bulldozer- or Zen-based processor). A separate binary distribution file is available for each target computer platform and audio plugin specification.  If supported on a specific processor, the plugin may internally utilize AVX2-optimized code.
  • Apple M1 native and Big Sur are supported.
  • Compatible Windows and macOS plugin software: Cubase, Logic Pro, ProTools, Ableton Live, Reaper, Presonus Studio One, FL Studio, Cakewalk, Nuendo, WaveLab, GarageBand, Vegas, SoundForge, Audition, Samplitude, Digital Performer, Mixcraft, Bitwig Studio, Edius, others.

4. Evouyn

by: Noisebud


Evouyn is an attempt to make decisions about the low end in both mix and home mastering situations easier. It measure the correlation between frequencies in the spectrum and warn you if the amount of low end exceed what’s known to sound good. This is not a exact knowledge and the situations where Evouyn will give you a warning  even though the amount of low end is perfectly fine are many. Even so, in most music produced today the correlation between parts of the spectrum can be predicted and with the help of little math you can calculate the approximate percentage that most probably sound good.

Evouyn are developed in collaboration between Noisebud and Saintpid Mastering. The idea sprung from the fact that many mixes sent for mastering either lack or have a crazy amount of low end, in most cases because of poor monitoring and/or the lack of proper acoustic treatment (egg boxes will not do). When you try to master something where you have to cut or lower the low end by sometimes up to 7-9dB (the energy doubles every 3dB) you will change the whole feeling of the track and the mastering engineer pretty much have to guess what you’re after. With a balanced mix you’re in for less of a surprise when the track return from the mastering house.

System Requirements

  • Windows XP or higher
  • 32bit plugins, work in 64bit hosts with a bridge (either built in or external such as jBridge) 
  • The VST folder need to have User permission set to read and modify
