5 Best Metering Plugins for Loudness (LUFS, RMS, True Peak)
We reviewed five of the best metering and analyzing plugins for loudness, four excellent free ones and a few bonuses for good measure.
In the present world of streaming and online broadcasting, mixing and mastering your audio to the standard maintained by specific platforms is essential for quality assurance. Metering plugins are the tools that help you ensure the specs of your music match the specified criteria.
What Do A Metering Plugins Do?
A metering plugin analyzes any audio you feed into it and provides various kinds of information about it. Streaming platforms use this information to assure consistency of their content. So, with a metering plugin, we can make sure our masters are compliant with our intended platform’s standard.
Let us have a look at some of the information provided by such plugins:
- True Peak
True Peak is the highest point an audio signal reaches on an analog system. In contrast, the regular peak meters we see in our DAWs calculate the same thing on a digital system. This is important because if your True Peak is higher than 0dB, it could cause clipping on analog amplifiers/players.
- RMS (Root Mean Square) Level
RMS is the average amplitude level over a certain period of time. Generally, this period of time is 300 milliseconds. However, some plugins let you adjust the time window as well.
- LUFS (Loudness Units Full Scale)
LUFS is the same as RMS, except this unit considers human ear perception. To simplify, our ears do not hear all the frequencies at the same level. So, for example, if you listened to a 60Hz sinewave and an 800Hz at 30dB amplitude, you would perceive the 60Hz sinewave as quieter than the 800Hz.
- Stereo Width
This analysis shows how wide the stereo field of your audio is. For example, audio with a thin line at the middle of such an analyzer is mono audio, whereas a moving, spaghetti-like visualization signifies stereo.
- Ranges
There are two kinds of ranges: Dynamic Range and Loudness Range. Both measure the range between the loudest and the quietest parts of your audio. However, Dynamic Range does so using peak metering (fast), while Loudness Range uses Loudness Unit (slow).
Thus, dynamic Range is useful for measuring how compressed elements such as drums, vocals, etc., are in your song. And Loudness Range shows, as an example, how different the loudness of your verse and chorus section is.
- Frequency Spectrum
A frequency spectrum displays how loud each frequency is in your audio in real-time. You can analyze a reference song using a spectrum analyzer and EQ your song’s master until it somewhat matches your reference spectrum to get a similar sound. Another similar kind of analyzer is a sonograph/spectrograph.
There are many kinds of metering plugins available nowadays — some focus on being easy to use, while others focus on being comprehensive enough to satisfy even the most seasoned experts.
SSL Meter
SSL Meter plugin offers a suite of metering tools with the capabilities to measure True peak and RMS levels, dbFS, phase coherence, stereo balance, and perform frequency analysis.
Key Features:
- Wide range of metering options
The plugin lets you select anything from various scaling systems—including Linear, Linear 2x, Non-Linear, Non-Linear 2x, and K-system (K-20, K-14, K-12) options. It also incorporates analog-style VU and PPM (Peak Programme Meter) meters.
- Phase and Stereo Evaluation
The plugin includes a Lissajous phase scope and phase correlation meter, allowing you to easily identify any phase discrepancies within your stereo mixes. The Lissajous phase scope provides a visual representation of the stereo field, enabling you to see how sound waves interact.
- Real-Time Frequency Analysis
Equipped with a 31-band Real-Time Analyzer (RTA), the SSL Meter visualizes the frequency spectrum of your mix, helping you identify potential problem areas. When you select a particular band, you can get the current (momentary) and maximum dBFS for that particular frequency range.
- GUI Convenience
The SSL Meter plugin allows for comprehensive rescaling, accommodating various screen sizes and layouts. Whether you require a larger view at 200% on a secondary monitor or a compact size at 50%, the flexible scaling ensures comfortable visibility and usability. Additionally, you get a pop-up of built-in help when you hover over any parameter that tells you what the parameter does.
Compatibility:
VST2, VST3, AU, and AAX for Windows and macOS.
Summary:
SSL Meter is a strong all-rounder for anyone who wants both classic analog-style VU/PPM meters and modern K-system scaling in one plugin — the 31-band RTA gives it real depth beyond basic level monitoring.
Process Audio Decibel
More Info & Price (Trial Available)
The flexible tool Process Audio Decibel, which also functions on your phone or tablet, provides you with a very effective metering system.
Decibel is a versatile measuring platform used as a plugin or independent program. Additionally, it has a unique audio driver that enables you to pass any program’s audio to the standalone application, guaranteeing almost complete compatibility with all production tools.
Markings on the semicircle indicate goal and peak levels, while quantitative monitoring systems in the screen’s center give integrated current, TrueDyn, and real max levels. Decibel would be considered a very good metering system if it were the only thing it could handle.
But Decibel has something much wiser up its sleeve: the meter panels you design with Decibel can be transferred to a mobile device for display, whether a phone or tablet running iOS or Android. This frees up your computer’s screen so you can focus on recording and editing.
Key Features:
- Multiple Meters
The plugin offers a variety of views and may hold numerous counters in a single instance. Most of them are aesthetically pleasing but typical examples of their kind, such as authentic frequency analyzers, VU meters, and max level meters in the bar and point styles.
- Super Meter
The Super Meter is, without a doubt, the most remarkable and inventive of Decibel’s indicators. A single, bold, semi-circular readout visualizes several LUFS volume readings. The semicircle’s bands display the combined and quick LUFS readings.
- User Interface
Decibel alone determines which meters show and how they appear. However, even after closing and restarting the plugin and the app, You will have no trouble initiating the connection between Decibel and Decibel Display. Layout creation can be a little challenging, but it’s not hard, and once you’ve achieved the desired appearance, you can store it as a preset.
Compatibility:
Standalone, VST2, VST3, AU, and AAX for macOS and Windows, plus iOS and Android companion app support.
Summary:
Decibel’s real standout is the ability to move your metering display to a phone or tablet, freeing up your main screen — a genuinely practical workflow advantage most metering plugins don’t offer.
Nugen Audio VisLM
More Info & Price (Trial Available)
VisLM has long been an industry standard for broadcast loudness compliance, and it’s the natural successor to fill the gap left by FENNEK’s discontinuation — covering the same core need with even broader standards support.
The plugin combines an instant loudness overview with detailed historical analysis, letting you hit compliance targets on the first pass rather than guessing and re-measuring. It’s compliant with an extensive range of international standards — ITU-R BS.1770 (revisions 1 through 4), EBU R128, the US CALM Act, ARIB TR-B32, Netflix’s own loudness spec, and several regional broadcast standards. The higher-tier VisLM-H edition adds up to 24 hours of loudness history logging, timecode-locked tracking, and exportable compliance reports — useful if you need to prove compliance after delivery, not just hit it during mixing.
Key Features:
- Extensive Standards Compliance — ITU-R BS.1770, EBU R128, CALM Act, Netflix, and numerous regional broadcast specs
- ReMEM Loudness Overdub — recalculates loudness instantly after any edit, without needing to re-measure the whole session
- True Peak Metering with inter-sample peak detection and timecode-logged violation history
- Up to 22.2 Channel Support, including stem monitoring and per-deliverable loudness measurement (added in recent updates)
- VisLM-H Edition adds up to 24-hour loudness history logging and exportable compliance reports
Compatibility:
AAX, AU, VST3, and AudioSuite for Windows and macOS (10.9.5 or higher), plus standalone. Avid HDX DSP version also available.
Summary:
VisLM is priced higher than FENNEK (discontinued) was ($299 for VisLM-C, $449 for VisLM-H) and leans more toward professional broadcast/post-production use than everyday music mixing — but for exactly the niche FENNEK covered, it’s arguably the more established, actively-developed option. If you just need straightforward music-mastering loudness checks rather than full broadcast compliance, Insight 2 or WLM Plus (both already on this list) may suit casual use better.
iZotope Insight 2
More Info & Price (Trial Available)
Insight 2 provides complete audio analysis, flexible GUI, and more.
Whether you are a music producer mastering a new song for Spotify or an engineer working on a blockbuster film, Insight 2 has you covered. Its interface has “modules,” each with a specific kind of metering.

Mastering The Mix LEVELS
More Info & Price (Trial Available)
Levels manages to become a welcome choice for both beginners and professionals alike.
The philosophy of Mastering The Mix Levels is simplicity. Instead of showing you everything it can on one page, it offers a certain kind of visualization per page. So, the information provided becomes easy to digest.
It has all the tools you could need to ensure your track fits the criteria of various music platforms such as Spotify, YouTube, or Apple Music. As we can see in the picture below, there are six kinds of meters in this plugin.
A few of the pages have filters inside them to help you dissect your audio material even further. We also liked the main input filter at the top of the plugin. It can turn the sound mono or playback only the Mid/Side or just the Left/Right channel.
This feature is beneficial for ensuring your track doesn’t have any phasing issues.
More experienced producers will be happy to know that the settings page lets you adjust the meter warning thresholds and the activation status of True Peak metering. Similarly, Mastering The Mix has provided various presets for beginners that help master your song to a specific platform’s standard.
Next, let’s have a look at each of the pages in the plugin:
“Peak” – Standard Peak Meter:
The Peak page shows the True Peak by default. You can also deactivate it by toggling it off on the settings page.
“LUFS” – LUFS Metering:
This page shows the LUFS short-term and the LUFS integrated. Clicking on the numeral values initiates them. We would have loved to see an optional LUFS momentary as well. However, it isn’t available.
“Bass Space” – Low-End Analyzer:
The Bass Space page is interesting. You can analyze the bass content of your track using this metering. It asks you to mute the bass drum and the bass to see how bassy the rest of the instruments are together. This implies you should use Levels on the master channel of your mixing project. Theoretically, it should help you keep the bass tight and clash-free.
“Dynamic Range” – Oscilloscope:
This page shows the relation between the loudest part of your music and the quietest. The lesser the number, the more your music sounds squashed and compressed. So, you can set a certain threshold (manually or with a preset) to warn you when the range goes lower than the set value.
“Stereo Field” – Width Visualizer:
This page shows how wide or mono your music is. An optional filter lets you analyze only a specific range of frequencies.
“LRA” – Loudness Range:
Sometimes confused with dynamic range, the loudness range also analyzes the relation between the loudest and the quietest parts of your song. However, this is done over a longer time scale using the Loudness Unit (LU). As with dynamic range, a higher value is desirable.
Key Features:
- Comprehensive Metering
With six kinds of metering, Levels is comprehensive for most use cases. However, it does lack a few basic features like a frequency spectrum or a LUFS-M meter. Despite the shortcomings, however, the straightforward nature of the plugin is a significant factor to consider for people who prefer simplistic workflow.
- Easy-to-use GUI
For the most part, Levels has almost no learning curve. Each plugin page is quite self-explanatory, and it also has an optional tooltip feature that gives you some helpful information for the first few times of using the plugin. However, on the side now, You cannot resize the GUI of this plugin.
- Helpful Presets
The presets available in the plugin are intended for commercial release. So, if you are looking to get your next song ready for Spotify, then this plugin is useful.
Compatibility:
VST2, VST3, AU, and AAX for Windows and macOS.
Summary:
LEVELS’ page-by-page approach makes it the most approachable metering plugin on this list for beginners — the Bass Space analyzer in particular is a genuinely useful, less common feature for checking low-end clarity.

This is brilliant for checking if certain instruments are clashing with others. Similarly, you could also use it for surround sound channels in a single track.
- Mid/Side Analysis
You can have the spectrum only to analyze the mid or side channel. This is handy for analyzing which frequencies of your audio could use a boost in stereo width and vice versa.
Compatibility:
VST2, VST3, AU, and AAX for Windows and macOS.
Summary:
One of the most widely used free spectrum analyzers for good reason — the multi-channel support and Mid/Side analysis mode give it genuine depth beyond a basic frequency display.
TBProAudio dpMeter5
The dpMeter 5 is an astonishingly capable loudness metering tool, particularly geared towards film/game audio.
What keeps dpMeter 5 different from the rest of the flock is its fully customizable RMS analyzer, LUFS-I/M/S, and Dolby Dialog Gated LUFS measurement. Dialog Gating uses code from Dolby itself to only analyze the loudness of the audio when dialogs are present. This ensures the consistency of volume based on dialog levels.
For music producers, dpMeter 5 also offers excellent features. No other loudness measurement plugin provides as comprehensive an RMS reading as this one does. So, if you are used to the classic, you needn’t give it up.
Another thing worth considering is that it has an input gain. So, you could adjust the gain until it matches your reference level without ever leaving the plugin.

- Presets
The plugin has several presets for various streaming platforms and broadcast standards. And with its built-in gain, you could easily match your audio to the reference.
Compatibility:
VST2, VST3, AU, and AAX for Windows and macOS.
Summary:
dpMeter5’s Dolby Dialog Gated LUFS measurement is a standout feature for film and game audio specifically — a rare capability to find in a free metering tool.
iZotope Imager 2
One of the most sought-after free plugins on the internet, iZotope Imager 2, is both a stereo width analyzer and a stereo enhancement plugin.
The analyzer section of this plugin is essentially the Sound Field module of the iZotope Insight 2 plugin. There are three kinds of analyzing views.
The two faders on the right side are the enhancers. The Width fader controls how wide your audio is, where 50% is the dry input. And similarly, the Stereoize fader controls how deep your enhancement effect is by introducing latency between your audio’s left and right channels.
Key Features:
- Simple GUI
The user interface of this plugin is fully resizable. And the multiple modes for imaging analysis make it handy regardless of which kind of imaging you’re used to previously.
- Stereo Enhancement
There are two stereo enhancement modes in this plugin. Stereorize I adds a phasing effect to your audio, whereas Stereorize II mode adds only subtle enhancements. They help make a mono sound seem wider and fatter.
Compatibility:
VST2, VST3, AU, and AAX for Windows and macOS.
Summary:
A genuinely useful two-in-one tool — the stereo analysis alone would be worth it, but the built-in Stereoize enhancement modes make it a practical width-shaping tool too, not just a meter.
Bonuses:
Waves WLM Plus Loudness Meter
More Info & Price (Trial Available)
WLM Plus has all three kinds of LUFS, True Peak, and Loudness Range metering.
What it does differently is that along with the True Peak readouts, it also has a True Peak limiter built into the plugin. So, matching your master’s loudness to a standard won’t even require you to switch between two plugins.
There is both gain and input trim to help you with the mastering process.
We also liked its warning and logging system, which records any clippings or under-threshold readings in your audio. However, since it doesn’t have a graphical view, there is no way to tell where the issue occurred.

There is an input low-pass and a high-pass filter for analyzing a set range of frequencies. Similarly, you can also choose to measure a specific channel of your audio.
- Limiter
Waves offer an in-built true peak limiter to help you with your mastering process. However, this may or may not be valuable as you could already have a favorite limiter for mastering. However, for mixing dialogs and so on, where you don’t typically introduce a huge amount of limiting, this may come in handy.
- Presets
The plugin has many presets for platforms like YouTube, Spotify, etc. The warning feature works great for making sure your audio is proper.
- Surround Support
The WLM Plus supports mono, stereo, 5.0, and 5.1 surround sound. So if you often find yourself working on low-budget indie projects, this could be of use.
Compatibility:
