Youlean Loudness Meter
Loudness Meter 2
The Benchmark for Accurate Loudness & True Peak Metering
In today’s streaming-first world, loudness is no longer subjective. Platforms like Spotify, Apple Music, YouTube, and Netflix normalize audio automatically, meaning poorly measured masters are either turned down, distorted, or dynamically flattened.
Youlean Loudness Meter has become one of the most trusted solutions for precise LUFS measurement, offering broadcast-grade accuracy in a free, accessible plugin.
Used by independent producers, mastering engineers, post-production studios, and content creators worldwide, Youlean provides transparent, standards-compliant loudness and true peak analysis without adding complexity to your workflow.
Whether you’re preparing a track for Spotify or delivering dialogue for broadcast, it ensures your audio translates exactly as intended.
System Requirements:
- 32 bit
- 64 bit
- VST / AU / AAX
- Windows
- macOs
Precision Loudness Measurement Without the Guesswork
Traditional peak meters only tell part of the story. A mix can peak at -0.1 dB and still feel quiet, or worse, be aggressively reduced by streaming normalization. Loudness Meter 2 focuses on LUFS (Loudness Units Full Scale) — the global standard for perceived loudness measurement.
By monitoring:
- Integrated LUFS (I) for full-track loudness
- Short-Term LUFS (S) for dynamic section analysis
- Loudness Range (LRA) for macro dynamics
- True Peak (TP) for inter-sample peak protection
you gain a complete understanding of how your mix will behave across platforms.
This allows you to avoid the common trap of over-limiting for loudness, preserving punch and clarity while still meeting streaming and broadcast targets.
Broadcast & Streaming Compliance Made Practical
Film, television, and streaming platforms all enforce strict loudness standards. Instead of manually calculating targets or referencing external documentation, Youlean includes built-in presets aligned with major international standards.
The Free version supports essential broadcast compliance formats including:
- ITU-R BS.1770-4
- EBU R128
- EBU R128 S1
- ATSC A/85
- OP-59
- ARIB TR-B32
- AGCOM 219/09/CSP
- ASWG-R001 HOME & PORTABLE
This ensures compatibility for TV, film, gaming, and online distribution without additional tools.
For streaming creators, LUFS measurement ensures your content avoids aggressive gain reduction on platforms that normalize playback volume.
Visual Analysis That Speeds Up Decision-Making
Youlean Loudness Meter isn’t just accurate, it’s visually informative.
The plugin provides:
- Real-time loudness graphs
- True peak histograms
- Loudness distribution analysis
- Scrollable history timeline
This allows you to pinpoint exactly where dynamics spike, where limiting is excessive, or where dialogue consistency drops. The interface is fully resizable and scalable, with a compact Mini View available for clean master bus monitoring.
All metering is calibrated and tested against official ITU reference materials, ensuring professional-grade reliability.

FAQ
RMS and Peak meters do not reflect how humans perceive loudness. LUFS applies frequency weighting based on psychoacoustic models, which is the standard used by streaming services and broadcasters. If you don’t measure LUFS, your mix may be normalized unpredictably.
- Integrated LUFS (LUFS-I) measures loudness across the entire track.
- Short-Term LUFS analyzes 3-second windows, useful for chorus or dialogue consistency.
- Momentary LUFS reflects near-instant loudness changes.
Integrated LUFS is typically the target measurement for streaming and broadcast compliance.
True Peak accounts for inter-sample peaks that occur during digital-to-analog conversion or codec compression (MP3/AAC). A mix that peaks at -0.1 dB on a standard meter can still clip after encoding. True Peak metering prevents hidden distortion.
Yes. The Free version includes essential international loudness presets such as ITU-R BS.1770-4 and EBU R128, making it suitable for TV and film compliance.
Yes. The Free version supports Mono, Stereo, and 5.1 channel configurations.
No. The plugin is optimized for low CPU usage and can run transparently on the master bus without disrupting workflow
