11 Best Loudness Metering Plugins (LUFS, RMS, True Peak)

Here I listed some of the best loudness metering plugins that you could find in 2025. Whether you’re mixing for Spotify, mastering for film, or just trying to keep your track from falling apart at -14 LUFS, these tools help you stay accurate without losing the creative flow.

From Goodhertz’s ultra-clean Loudness to SSL’s pro-grade Meter Pro and modern options like Decibel or Metric AB, each plugin here serves a purpose – helping you mix confidently and hit the right levels every time.

1. Goodhertz Loudness (FREE)

Starting with a perfectly relevant freebie from Goodhertz, Loudness is a simple but well-made volume control plugin that focuses on accuracy and clean signal handling. It avoids the small clicks or pops that can happen when automating volume in some DAWs, which keeps fades and transitions smooth.

The metering covers LUFS, RMS, and peak levels, giving a clear picture of how loud or balanced a track really is. It also includes a feature that automatically adjusts to a target loudness level, which helps when matching references or preparing mixes for mastering.

• Keeps volume automation perfectly clean, so no unwanted clicks or digital pops sneak into the mix
• Gives you real-time LUFS, RMS, and peak readings that make it easier to control overall loudness while staying consistent across different tracks or sessions
• The auto target feature instantly matches your mix to a chosen loudness level, saving time when preparing for mastering or streaming standards without needing a calculator or external meter.
• Simple fine trim control for those last balance tweaks.

2. zplane FENNEK

FENNEK by zplane is a reliable loudness metering plugin designed for modern broadcast and streaming standards.

It keeps your levels in check across all the major platforms like YouTube, Spotify, and Apple Music, making sure mixes meet their targets without any surprises. It’s been useful during mix checks before delivery, helping catch small level inconsistencies that might otherwise slip through.

The loudness history view is especially useful for spotting small dips or jumps over time, and it handles surround formats up to 7.1 without a hiccup.

• Includes official loudness presets for streaming and broadcast platforms like Spotify, Apple Music, and EBU R128, keeping your work compliant.
• The history view shows loudness trends across time, which really helps when reviewing long sessions or film mixes
• Works seamlessly in stereo, 5.1, and 7.1, so you’re covered for any project format
• Lets you customize the layout to hide meters you don’t need, keeping focus on the data that matters most.

3. ADPTR AUDIO Metric AB

I like keeping a few reference tracks nearby when mixing, and this plugin makes that process way easier.

It lets me flip between my mix and commercial tracks without touching the mouse or guessing volume levels. Metric AB by ADPTR Audio handles loudness matching automatically, so I can actually compare tone, space, and balance instead of being distracted by level differences. The meters are clear, the playback stays in sync with my DAW, and the whole thing just works without getting in the way.

• 16 reference tracks. Simple drag, done
• Four loudness match modes that instantly even out playback levels so you can make honest comparisons between your mix and commercial tracks without distraction or bias creeping in
• Detailed meters show spectrum, LUFS, stereo width, and dynamics – everything you need to spot what’s missing or overdone in your mix.
• Cue sync. No scrolling

4. Youlean Loudness Meter Pro

Loudness metering isn’t exactly exciting, but it’s one of those things you can’t skip if you care about consistency. That’s where Youlean Loudness Meter Pro really earns its place. It gives clear LUFS and peak readings without slowing down your session or eating CPU, which makes it easy to keep things in spec for Spotify, YouTube, or TV work.

I like that it can show dynamics visually too, so it’s quick to spot when something’s been pushed too hard. Simple, reliable, and does what’s needed without unnecessary fluff.

• Reads LUFS and peaks accurately, staying true to broadcast and streaming standards.
• Has instant drag-and-drop analysis that loads your track and spits out a full loudness report in seconds
• Includes dynamic range monitoring so you can see when compression is killing punch or balance
• Resizable view
• Exports graphs and data for reference or sharing, straight from the plugin.

5. SSL Meter Pro

Metering is one of those areas that separates a clean mix from a messy one, and SSL Meter Pro makes that job a lot easier. It combines all the essential tools – loudness, true peak, VU, PPM, spectrum, and phase – in one flexible window that feels familiar if you’ve used SSL gear before.

I quite like how it supports immersive formats up to 7.1.4 without getting bloated or confusing, which makes it useful for both stereo mixes and Atmos sessions. The real-time analyzer is solid too, giving a quick visual read on frequency balance when something feels off!

Here are some of the main features:

• Full loudness suite with momentary, short-term, and integrated views so you always know where your levels sit.
• Handles multichannel formats up to 7.1.4, great for anyone mixing immersive or film content.
• Includes classic VU and PPM meters that feel like old-school hardware but behave with modern precision.
• The Lissajous phase scope
• 31-band RTA gives a clean real-time frequency view for identifying build-ups or missing energy.

6. TC Electronic Loudness Meter

Loudness metering can feel dry until you’ve got something like LM6 by TC Electronic sitting on your master bus. It takes a different approach with its radar-style display, giving a visual sense of dynamics over time instead of just throwing numbers at you.

That view makes it easy to catch gradual level drifts or over-compression that standard bar meters might miss. I’ve seen it hold up well on both stereo and surround mixes, and the true-peak readings stay reliable even when pushing heavy masters close to the limit. It feels more like watching how your mix breathes rather than just monitoring stats.

• Radar-style display shows loudness movement over time, not just static values.
• True-peak detection
• Offline measuring in Pro Tools analyzes audio faster than real time – a serious time saver.
• Fully compliant with global loudness standards, keeping mixes ready for broadcast or streaming

7. Mastering The Mix LEVELS

Mixing can get messy fast when you’re juggling loudness, dynamics, and stereo width all at once. That’s why I like tools that keep things simple and show only what really matters. LEVELS by Mastering The Mix does exactly that. It gives clear visual feedback for loudness, phase, dynamics, and bass balance without drowning you in data.

I usually keep it on my master bus while working – it’s like having a quiet assistant that points out problems before they turn into real mix issues. Nothing flashy, just genuinely helpful info that keeps your track sounding clean and balanced.

• Clear metering for loudness, phase, and dynamics so you can catch problems before export
• The Bass Space tool checks low-end buildup and shows if anything’s hogging space below 300Hz.
• Dynamic Range and Loudness Range meters help prevent over-compression while keeping the track punchy
• Stereo field display visualizes width and correlation, perfect for spotting phase issues early.
• Comes with presets for CD, streaming, club, and YouTube, making it easy to stay within proper loudness limits.

8. PROCESS.AUDIO Decibel

Some plugins try to do too much, but this one finds a clever middle ground between practicality and flexibility. It’s not just another on-screen meter – it actually lets you use phones or tablets as real-time meters around your studio, which is genuinely useful when keeping an eye on levels while mixing.

Decibel by Process Audio feels more like a flexible metering hub than a single plugin. It’s quick to set up, visually clean, and its “Super Meter” module gives a solid overview of loudness, dynamics, and peaks in one glance. The mobile connection setup can be a bit finicky the first time, and the interface sometimes feels dense if you load too many modules, but once it’s configured, it’s a solid companion for anyone who wants visual metering without cluttering their main screen.

• Mobile meters anywhere. Instantly turn your phone or tablet into a live display for your session.
• The Super Meter gives a detailed visual of LUFS, TrueDyn, and True Peak all at once, wrapping everything into one clean graphic that reacts smoothly to your mix in real time
• Drag, drop, done. Quick offline analysis when you need loudness numbers fast.
• Works easily with Logic, Pro Tools, Studio One, and Premiere, no complex routing needed.

The setup can feel a little crowded if you load too many modules, but once it’s dialed in, it runs steady.

9. Youlean Loudness Meter FREE

Getting loudness right is more about precision than volume. This plugin keeps things simple by showing LUFS, true peak, and dynamics clearly, so you always know where your mix stands. Youlean Loudness Meter Free makes it easy to meet TV and streaming specs without crushing your sound.

It’s accurate, light on CPU, and the visual layout makes sense even when you’re deep in a mastering session.

• Accurate LUFS and true peak readings for mixing and mastering reference
• The dynamic range display shows when compression starts stealing your punch, helping keep mixes open and natural
• Preset modes for film and streaming, so you don’t have to guess which level standard to follow

10. TBProAudio dpMeter5

This one’s a no-nonsense metering tool that just focuses on accuracy and flexibility. dpMeter5 reads RMS, LUFS (EBU R128), dialog-gated, and TruePeak levels across multiple channels, making it reliable for both stereo and surround work. It’s light, stable, and the resizable interface is a nice touch for small or large screen setups.

• Multi-channel loudness and TruePeak metering, up to 5.1, for consistent monitoring in any mix format
• GUI scaling and preset management, so you can save your workflow and keep things organized.

11. PA bx_meter

Sometimes dynamics get lost after hours of tweaking, and that’s where a proper visual check makes a difference. Seeing how your mix moves between loud and quiet moments can reveal things your ears start to ignore after a while. bx_meter by Brainworx gives that visual feedback clearly, showing peak and RMS levels, plus the dynamic balance between them.

The Mid/Side view is especially useful for spotting when the stereo field starts collapsing or pushing too wide. It’s not a flashy plugin, but it’s one that helps keep perspective when fatigue kicks in.

• Peak and RMS metering with centered dynamic LEDs for quick level reference.
• Mid/ide and stereo modes
• Includes weighting filters (A, C, K) for realistic loudness perception, matching what your ears actually hear
