What Is the Best Plugin for LUFS Metering? (Here’s Why It’s L4 Now)
If you release music on Spotify, Apple Music, or YouTube, you’ve probably heard of LUFS—but most producers still don’t know how to measure it properly or what plugin to use.
LUFS (Loudness Units relative to Full Scale) is the standard streaming platforms use to normalize the volume of your music. Go too loud, and your track gets turned down. Too quiet, and you risk sounding weak next to everything else.
That’s why I’ve started using the Waves L4 Ultramaximizer — and if you want one plugin that gives you loudness control + accurate LUFS metering all in one place, this is it.
Why LUFS Metering Matters in 2025
Streaming platforms don’t care about your peak level or your RMS. They look at integrated LUFS to determine how loud your song should play back.
- 🎧 Spotify normalizes to around -14 LUFS
- 📺 YouTube aims for -13 to -14 LUFS
- 🍎 Apple Music also uses LUFS and turns down anything too hot
If your mix is sitting at -7 LUFS, it will likely be turned down—but if you used upward compression to get a denser sound without raising the peaks, you might beat the penalty.
Why Waves L4 Is the Best Plugin for LUFS Right Now
Here’s why I’ve made L4 my go-to loudness plugin for LUFS metering and streaming prep:
- 📉 Built-in LUFS Display – No need for third-party meters
- 📈 Upward Compression – Raise quiet sections to make your track feel louder without tripping normalization
- 🔊 True Peak Limiting – Prevent intersample clipping post-conversion
- 🎛️ Gain Match – Accurately A/B your sound before and after limiting
It’s not just a limiter — it’s a full loudness mastering tool.

How to Use L4 for LUFS
Here’s the quick workflow I use before uploading any track:
- Set the Output Ceiling around -1 dBTP (true peak)
- Dial in your limiter mode (Modern or Safe for most use cases)
- Use upward compression to bring life into the quiet sections
- Watch the LUFS meter to land between -14 and -9 depending on genre and platform
- Use Gain Match to check if it sounds good at normalized volume
This keeps your song streaming-ready without sounding weak or overcompressed.
Why You Might Be Getting Turned Down on Spotify
If you’re only looking at peak levels and not LUFS, your song might be getting automatically reduced in volume by 3–6 dB. That kills the vibe—especially when you switch to the next track and it suddenly feels louder.
L4 gives you the tools to avoid that and control your loudness with more precision than most other limiter plugins.
