This LUFS guide exists because loudness is one of the most misunderstood parts of finishing a record — and getting it wrong costs you. Not in a catastrophic way, but in that quiet, frustrating way where your track sounds slightly off on Spotify compared to everything else in the playlist, and you can't quite figure out why. LUFS stands for Loudness Units relative to Full Scale, and it's the measurement standard every major streaming platform uses to normalise the volume of every song on their service. Once you understand it, a lot of things click into place. Use the interactive tool below to check your master against all the major platforms in real time.

Values based on publicly available platform documentation. Always verify with your distributor before final delivery. LUFS = Loudness Units relative to Full Scale (EBU R128 standard).
What LUFS Actually Means (Without the Jargon)
Let's keep this simple. LUFS is a unit of measurement for perceived loudness — not just peak level. It takes into account how human ears actually hear volume, which is why it's more useful than older measurements like dB peak or RMS. You could have two tracks with identical peak levels and one sounds significantly louder than the other. LUFS captures that difference. The "Integrated" LUFS measurement is the one that matters most for streaming — it averages the loudness of the entire track from start to finish.
The standard was developed by the European Broadcasting Union (EBU) as part of a specification called R128. Broadcasters adopted it first. Streaming platforms followed. Now it's the lingua franca of loudness across the entire music distribution chain. If you're sending music to any platform, you're dealing with LUFS whether you know it or not. Better to know it.
Why Streaming Platforms Normalise Loudness
Picture this: you're listening on Spotify. Song one is a quiet acoustic folk track mastered at -18 LUFS. Song two is a hyper-compressed EDM banger sitting at -6 LUFS. Without normalisation, the second track would blow your head off the second the playlist moved on. Nobody wants that — not the listener, not the platform.
So Spotify, Apple Music, YouTube, and every other platform measures the integrated loudness of each track in their system and applies a volume adjustment at playback. Your track doesn't change. The playback volume does. That's the key distinction. The audio file stays exactly as you delivered it — the platform just turns it up or down when it plays.
Here's what that means for you in practice. If you master your track to -8 LUFS thinking it'll sound louder than everything else, Spotify turns it down to match their -14 LUFS target. All that extra compression you used to squeeze the loudness up? It's now playing at the same level as everything else — except your track sounds more squashed and less dynamic. You traded sonic quality for loudness you never actually got. Painful, right?
The Loudness War Is Over — and Streaming Won
For about three decades, the music industry waged a war on dynamic range. Labels and engineers pushed masters louder and louder, chasing the psychological edge of sounding bigger than the competition on the radio. Transient detail got crushed. Dynamic range got squeezed. By the late 2000s, some commercial masters had almost no dynamic range left at all — just a solid wall of compressed, limited sound.
Streaming normalization ended all of that. Overnight, there was no competitive advantage to being louder. A track at -8 LUFS gets turned down. A track at -14 LUFS plays as-is. And the -14 LUFS track, mixed with care and dynamic range intact, almost always sounds better. If you want to go deeper on what happens to audio at the mastering stage — and why dynamics matter so much — our guide to what audio mastering is covers it in full.
Integrated LUFS vs. Short-Term vs. Momentary: Know the Difference
Your loudness meter shows more than one number. Here's a quick breakdown of what each one means, because mixing them up leads to bad decisions fast.
Integrated LUFS is the average loudness across the entire track. This is what streaming platforms use. This is what you target. Short-term LUFS measures a three-second rolling window — useful for checking how loud a chorus or verse is relative to the rest of the song. Momentary LUFS covers a 400ms window — useful for catching loud transients in real time. And then there's LU Range (LRA), which measures the variation between the quietest and loudest sections. A high LRA means a dynamic mix. A low LRA means something heavily compressed.
Focus on integrated LUFS for streaming delivery. Use short-term and momentary as reference tools while you mix. Check our full audio recording glossary if you need plain-English definitions for any of the technical terms that come up in loudness metering — it's a genuinely useful reference to have bookmarked.
How to Measure LUFS in Your DAW
Most modern DAWs include a loudness meter as part of their metering suite. Logic Pro has a built-in loudness meter. Pro Tools has one. Ableton includes a loudness meter in the mastering chain. If yours doesn't, Youlean Loudness Meter is a free plugin that sits on your master bus and gives you integrated LUFS, LU Range, and true peak all in one clean interface. It takes about 30 seconds to set up. No excuses for not measuring.
The workflow is simple. Drop the loudness meter on your master bus. Hit play on the full track from the very beginning. Let it run all the way to the end. At the end, your integrated LUFS reading shows you exactly where you sit. If you're at -9, you've got some decisions to make — either adjust your limiter settings to reduce the gain reduction, ease back on compression earlier in the chain, or simply accept that the platform will turn you down and focus on making the track sound great at that level rather than loud.

True Peak: The Other Number That Matters
Integrated LUFS isn't the only delivery spec you need to hit. True peak matters too. A lot.
When streaming platforms transcode your audio file into compressed formats like MP3, AAC, or Ogg Vorbis, the encoding process can actually cause inter-sample peaks — tiny moments of digital distortion — to appear even if your original file had no clipping at all. True peak metering accounts for this. It measures what happens between digital samples, not just at them. Keep your true peak at -1 dBTP or lower before you deliver. Some engineers go to -0.5 dBTP. It costs you almost nothing in loudness but protects you from codec distortion on every platform that re-encodes your file.
This is also why getting your mix sounding right before you hit the limiter makes such a difference. Read our walkthrough on how to prepare a mix for mastering to make sure the session you hand off to the mastering stage — or take into your own mastering chain — is set up correctly from the start.
Genre and the Case for Going Quieter
Not every genre should be targeting -14 LUFS. That's a streaming-average recommendation, not a universal law. The right target depends entirely on the music itself.
Classical, jazz, and acoustic music often sound best around -18 to -23 LUFS integrated. These genres live and die by their dynamic range. A piano concerto with a -23 LUFS integrated level will still play at full volume on any streaming platform — the platform won't turn it down — and it'll sound stunning because the dynamics are fully preserved. EDM, hip-hop, and heavily produced pop typically land between -9 and -14 LUFS. That's not because they're trying to "win" the loudness war — it's because those genres have less natural dynamic variation, and a -14 LUFS target feels appropriately full and dense for the material.
The important thing to understand is that going louder than your genre norm gains you absolutely nothing on a normalised platform, and costs you dynamics. Go quieter than your genre norm if the music demands it. Your listeners will thank you. Getting the balance right is where mixing and mastering diverge in purpose — mix for clarity, master for level and consistency.
What to Do If Your Mix Isn't Hitting the Target
Let's say you run the integrated measurement and you're sitting at -8 LUFS. Here's how to address that without wrecking the track.
First, ease back on your brickwall limiter. The limiter is almost always the last plugin in the mastering chain, and it's the main tool pushing integrated loudness up. Reduce the input gain or ceiling until your integrated LUFS drops to around -14. Listen carefully. Does it still sound full? Does it have more punch and clarity now that you've taken the foot off the limiter? In most cases, yes. Dramatically yes. If the track still sounds thin or lacks presence at -14, the problem is likely in the mix — check your vocal mix levels, look at how much compression you've stacked across the full mix bus, and verify your low end isn't eating all the perceived loudness. And if you're looking for free mastering tools to help get there without spending anything, our best free VST plugins guide has solid options for limiters and metering.
Monitoring Accurately Matters More Than You Think
You can know every LUFS target by heart and still deliver a bad master if your monitoring environment lies to you. Coloured headphones that boost bass make you pull low end out of the mix that should stay. Consumer speakers that flatter the mid-range make vocals sit wrong on a flat system. The tools you use to listen while you mix and master have a direct impact on what you deliver.
Invest in flat, accurate monitoring — either a quality pair of closed-back or open-back studio headphones, or a pair of nearfield monitors placed correctly in a treated room. Our roundups of the best studio headphones and best studio monitors cover every budget tier. Getting your monitoring right is one of those investments that pays off on every single session you do — not just mastering sessions.
A Final Word on Delivery
Always deliver a 24-bit WAV or AIFF file at 44.1kHz or higher to your distributor. Never deliver an MP3 for mastering or distribution upload — you're starting from a compressed file that's already lost information, and then the platform compresses it again. Deliver lossless. Let the platform handle the transcoding. Keep your gain staging healthy, your limiter set conservatively, your true peak below -1 dBTP, and your integrated LUFS within the target range shown in the tool above. That combination gets your music sounding its absolute best on every platform — not just one of them.
Loudness is one of the last things most producers learn to get right, and one of the first things listeners feel — even if they couldn't tell you why. Use this LUFS guide and the interactive tool above every time you finish a master, and you'll never send a track to a streaming platform without knowing exactly what's going to happen to it.
