Getting your loudness right is one of the most important parts of mixing and mastering. Too quiet, and your track might sound weak compared to others on playlists. Too loud, and streaming platforms like Spotify or Apple Music will turn it down — and worse, it might distort or lose dynamics. That’s where loudness meters come in.
A loudness meter helps you measure LUFS (Loudness Units Full Scale), true peak, and dynamic range so you can confidently deliver release-ready music. In 2025, there are more options than ever — from free meters to professional plugins trusted in world-class studios.
Let’s break down the best loudness meters you can use right now.
1. iZotope Insight 2
One of the most complete metering suites available. It covers LUFS, RMS, dynamic range, true peak, and even a spectrogram view. Insight 2 integrates beautifully into professional mastering workflows.
2. Waves WLM Plus
Waves’ WLM Plus loudness meter is widely used in broadcast and music. It’s affordable, easy to read, and gives precise LUFS and peak monitoring. Great for anyone working across both streaming and broadcast standards.
3. Youlean Loudness Meter 2 (Free + Pro)
This is a favorite among independent musicians because the free version is powerful enough for mastering. It includes LUFS, true peak, and exportable reports. The Pro version unlocks more customization and detailed analysis.

4. NUGEN VisLM 2
Trusted in both music and post-production, NUGEN’s VisLM 2 is the gold standard for broadcast compliance. It’s pricier but incredibly detailed, with historical loudness analysis and presets for every major platform.
5. FabFilter Pro-L 2 (Built-In Metering)
While Pro-L 2 is technically a limiter, its built-in loudness metering is excellent. Many mastering engineers rely on it to monitor LUFS and true peak while applying final limiting.
Why Loudness Meters Matter in Mastering
Streaming platforms normalize music to around -14 LUFS integrated (Spotify) or -16 LUFS (Apple Music), but true peak compliance is equally important. A good loudness meter helps you:
-
Avoid distortion and clipping
-
Maintain dynamics without being overly squashed
-
Deliver tracks that translate consistently across platforms
